I am hoping I can find some help in here with a couple problems I am running into on this system that would make it so much better to me.
The system is basically an Android box utilizing the touch screen and monitor of my Uconnect 8.4 head unit. The naming in the settings is rk3188 and is running on KitKat 4.4.4, so it is some variant of the Android TV boxes. If there are other specs or info that are needed to help in possibly fixing my issues please let me know.
Issue 1: although not major, there is no option to have OK Google from any screen. Having this option for a car system is obviously something helpful. In the settings of the Google App trying to access the menu for OK Google detection doesn't work, so I can't even get to the screen where that option lives. I have the most up to date version of Google App and Google Play Services. I have Google searched on ways to fix this but nothing has brought that ability up. I know Android version 4.4.4 was capable of this. There was another app that utilized Googles voice engine and allowed this function but Google made him stop using their servers and killed that as an option.
Issue 2: this is the biggest bother to me and I could not find anything even related to what's happening in my searches. The system comes loaded with some apps and using Launcher3 for its front end, it has big buttons but offers almost no ability to customize it. The bottom row has apps that you cannot switch out to anything else, and 3 of them I will never be using. The system works but is not as nice as it could look or function. The obvious answer is to use a different launcher which is where the problem arises. I have tried to use Nova and Apex so far with the same very frustrating outcome. After the install everything is great, I can set the screen up to look amazing and add icons and functionality that really make it a great experience. So everything is working lovely then I shut my truck off and go do whatever. The next time I come back I start the truck up everything loads fine, the new launcher and everything I did to it is working just as expected until about 5 minutes in the screen goes black for a second and then the system goes through a factory reset. Really? Are you kidding me? The first couple times I thought maybe I hit something because I hadn't fully put my truck back together but after playing with it more and having the system factory reset 5 other times I have concluded it is related to changing the launcher. I tried Nova first, then I tried Apex with the same outcome and same sequence of events. Obviously it's annoying everytime testing this because updating and reentering my info everytime just to try the launcher again is time consuming. The last test the only thing I did was a different launcher so that has to be it, but why and how can I fix it?
If anyone has any clue how using a different launcher would cause a factory reset to happen please help me out. Or if there is anything I can do to this system to prevent that. My last resort thought would be to root it but I read someone else who has this system that rooting it caused screen layout issues and made things go 90 degrees off? The loaded apps in the system have touch screen calibration and screen resizing which might be necessary for this to function with the monitor.
Thanks for any help.
I spoke with someone else that has the system and they are not having any issues with running a different launcher so something happen to my particular device. I contacted the company and they will be getting me the firmware to refresh it and hopefully that fixes the resetting issue.
i am looking to get this also. I am very curious how you like the device - it looks great though a bit out of date. Waze & email should work well. How much storage does it have? Can you add a sd card or something?

I'm getting a new unit sent out, it seems there are 2 versions and for whatever reason mine wouldn't let me customize the launcher.
But even though it's outdated, every app I tried worked just fine, they still install the latest versions. The system has 8gb of on board storage and a microSD card slot that is mainly for loading maps for offline navigation. I think you can still access it for other uses, but they have a better option for that. There is a USB input for flash drives or external drives. I tried my 2TB external drive on it and it accessed my movies fine from it.
How did you get it installed? Who?
got any pics?
Actually I would be interested in this too, I have an Alfa Romeo and the Uconnect 6.5 (european version) which isn't that great, it would be nice to attach a sort of box with ARM hardware running on Android and using the display and touch of the existing Uconnect. The question is, how this can be done?

I would check out this thread. It has two videos that walk you through the entire process - great info!
I also bought this latest Android system V4 2 weeks ago. Auto launcher pro app is very good working. At the moment there is a issue with the system time, which is not correctly synchronized with gps time. Carperformance Team is working on a fix for that. How can I get root Access for this Android 7 System?

glad to hear i'm not going crazy with the clock but there is an issue.
I just bought and installed a V4 a couple weeks back too.
i must have left a loose connection cause i keep having to recall the touchscreen for android. I half-arsed the install cause we were leaving for a 2k mile roadtrip the next day- need to take it apart and do it right. Luckily you can connect a usb mouse in to trigger the calibration app.
id also love root- at the moment im trying to figure out if the one usb port is safe to connect an A to A usb cable into to get ADB. apparently on some versions of nvida sheild, you can. If they provide a firmware update for the clock fix then maybe that gets us an image to futz with for root.
a keyboard also works in teh usb port and i've tried a handful of key combos during boot to get to recovery but haven't stumbled on it yet.
I'll post back if i find anything

Hi @michaelk
Good to hear that I am not alone here with this special system V4. Except for the issue with the system time and no root access, I am fully satisfied so far. I hope to fix it soon. If we had root access then we could solve this issue with the system time with some time apps ourselves.
Thank you for your experiences.

wiring harness investigation
so played around some today.
I've got an issue where I need to recalibrate the screen almost every time I boot. it seems the box (or card added to the radio?) forgets things and only works the bottom right corner and also seems to rotate 90 degrees at boot. The end result is unusable screen. I think carperformance is just a reseller because of their response. They're friendly and reply quickly but are really unable to help. The first answer was just randomly fiddle with screen and try to find calibrate setting and reboot- that proved impossible and on my own I discovered a 6 dollar USB mouse from the Walmart could be used to navigate to the calibrate app. When I inquired again when it got more frequent they basically said it's not normal and offered no help except to adjust a personalization setting to run calibrate on boot- that only works once that I can figure (might be related to weird time bug)- so I settled on having tasker run calibrate on each boot. I wonder if there is a battery in the box that needs changing but the warranty sticker keeps me out for not- might add an external battery to keep it alive for a longer time to minimize the rebooting
Anyway took everything apart today to double-check and can't find any connection issues. I traced the harness a bit to try and understand a little and basically, the skinny cables run the daughterboard to snag the screen output and the touchscreen input. But i wanted to figure out what is tapped from the radio harness to the large white plug on the box and see if anything going on their .
DISCLAIMER- I NEED TO CONFIRM (it was hot - laughing) but basically seems what is tapped in radio harness is:
1) power and ground also
2) L&R aux audio signal- interesting here is they tapped a single ground (physically next to the right signal) for common. Earlier i had the RAX hack and their harness used a ground for each L&R and their aux input worked all the time without the little plugin shunt thing to trick aux input. When i dug some more and found a pin diagram from mopar I found that the 'left' ground is actually labeled "aux audio device detect signal" I need to play some more to see what happens but my guess is if we put a switch on that to short it to ground then the aux would just work to avoid the hokey plug.
3) Here's the fun- holding the screen to flip inputs could be the daughterboard running things. BUT since it also reacts to the left steering wheel button pack and switches inputs itself when you need the reverse cam- i figured it reads the can bus. and sure enough, it looks like it taps CAN IHS (+) and CAN IHS (-). Very cool that it would get into the whole bus and read anything- BUT since there are other FCA vehicles that don't auto-switch inputs on revers and they have alternate connections it seems the real dev is not involved to update things to sniff for other reverse signals. Reading around here- seems that there is probably a custom serial port someplace in the box that reads this and there's probably no documentation for us to do anything ourselves. But one can hope...

So the spec for the chipset for the V4 says it can handle an OTG port and a couple (maybe 3?) other USB ports. Obviously, the box only has the one USB A port visible on the pigtail. I wish we could get in the box and look for a header for the OTG port to help rooting but.... the darn warranty sticker.
on the FCA/Dodge side of things- I have a Durango with a USB port and SD card reader in the dash (USB Media "Hub" Apparently, FCA uses USB Mini B connectors to interconnect all the ports and the radio. They use latching connectors that are keyed but if you undo them there's a standard USB mini B in there. They do some odd male/female things so you have to pay attention to where you undo cables, but bottom line you can undo the connector on the back of the dash's USB port and stuff a USB mini B female on it and connect it to whatever host device you want.
I first tried an old laptop in case there's anything weird going on. My Dash "Hub" actually has 2 mini-B connectors and a multipin auto harness. Without the harness when you connect it to windows it sees a USB Hub, but the USB port was still dead. So I assumed it needs power from the harness on the back of the dash hub and connected that. UP popped up a USB mass storage device which I believe is the SD card reader- didn't get around to confirming and then the USB port also comes to life. Knowing that it was safe at that point I connected it to the USB A Host port on the box and presto chango now I have the in-dash port connected to the android tv box without any exposed wiring.
Connected the "android auto dongle" through the cars USB port and that works perfectly. I ordered a used 2 USB dash hub from eBay (later model years have 2 and will see what that does. The pictures of that also show the 2 mini B ports- I'll play some more when I get that. I'm not sure what is in those dongles but from the other folks hacking android auto into older models (by using newer radios) apparently, one port works for android auto and the other doesn't. The scuttle is its a body module programming thing but I wonder if maybe there's something physical in there and so the dongle won't be necessary any longer with the new hub? My other thought is if the two USB min B jacks allow you to connect to 2 different hosts- I would try one on the original Uconnect (in case I ever need to update the software) and the other for the android TV box.
So apparently the android tv box handles hubs just fine. As I mentioned earlier it handles a mouse or USB keyboard fine. Also, I played around and connected my hotspot by USB instead of wifi so the device sees it as a modem and that works just fine- so I assume a USB modem works out of the box too. (again odd if that works that carperformance sells a hotspot and not USB modem- like they don't know what the box can do)
I disassembled my display 2 times until it worked. After the first start, I had a black screen. I thought that was it... After 3 times it finally worked. I also had a cable on the plug which has easily resolved. I think you will also have a loose contact somewhere. One time I also had the display calibration gone. Then I connected my old usb keyboard and could then start the display calibration. I reset the system before. So far, the system works without problems. I also have a passive 4-way usb hub to connect.
I have already connected cables for the frontcam but have not yet moved into the engine compartment.
In the video tutorial of Carperformance, you can see when you switch to drive, the display then changes to the frontcam or signal from the cam, but the display does not change to the Frontcam signal with me.
Do you have with you the signal on the display of the camera when switching to drive?
Adw2 = bad mix
Went back and forth many times in email and turns out my calibration issue was probably all ADW2 launcher, guess it conflicts with whatever app they use to communicate with the display.
in the process of troubleshooting I got the update zip for the current version but I don't think those have recovery partition in there and so can't help root? I need to read some more.
I've ripped everything apart like 12 times with the screen, so that my front cam is not connected right now. For the brief time I had it, it was connected to one of the smaller video in pin connectors and don't think it worked in drive by itself, but can't really say for certain. I think certain models can't get the canbus command to see reverse and if I understand they connect in to the video in on the main connector and then use a point on the car that is energized to trigger the switch on that connection. If your adventurous they seem to have to flip a dip also. I think it's the Cherokees or maybe grand Cherokee so maybe Google their thread's? This site gives connector pin outs
http://connectors.dcctools.com/home.htm
There might be a lead for the drive on your shifter if lucky. I think I read the reverse shoulder comes from a body control box in the passenger wheel well?
Also they're super friendly and never wrong when you email but they can be brief. So you could ask if there's a dipswitch to flip to enable auto switching one of the inputs. Hec maybe we should just ask for a table of where the dips do...
(Sorry for any typos... Will try to edit later)
Supposedly it is enough to connect the extra input cable for DVD or CMMB. That answered me Carperformance. Before, I had no external input cable connected. That's why no signal came. The OEM rearcam works flawlessly.
Also, I forgot, they have a workaround for the clock bug
For the clock there is a fix

It's a cheaper fix but so no solution. Carperformance should offer a software update with root access. Then we would be satisfied. We should expect it for the money.
My frontcam is working now good.
You already tried Android auto? Which USB dongle do you use? Do you need a special app for this?
My China usb dongle does not want to connect properly with my oneplus 6T.
Edit:
Android auto is working with Pumpkin USB dongle and autoplaybox app. The noname China scrap goes back to shop.
The time fix is working until now also. Thanks for this info. The carperformance, they wrote or informed the affected people who ordered it. I did not get any info.

besides powering your camera and connecting the yellow RCA video signal did you have to do anything else?
something with the red signal wire maybe?
I cant consistently get a signal on my front cam and not sure if the camera is bad or my setup

few other notes for others-
FCA "aux audio device detect signal" harness line is actually normally closed (I think shorted to ground)- if you break the connection the oew radio flips right to aux in. make the connection again and it flips back to previous input.
the in dash usb port is infact a powered hub. I originally had a usb + SD card combo and replaced it with 2 usb port and works fine. FCA uses mini b connections to it- just use a usb a to mini b cable to connect it to the android auto box and your indash usb port(s) will work on android auto (And provide more watts to charge your stuff). oddly either dahs hub has a second usb mini b connector that i played around with a little but never could figure out what it does
more can bus fun! - i updated the dongle firmware on the android auto dongle sold direct from carperforance and now it has a beta feature to map buttons. somehow it seems to be sniffing the canbus through the android tv box. it has arrow keys, numbers, enter, etc and you use the app to select the input to assign then you press the same button on the car twice- it sniffs the signal and assignes it. I My durango has the button packs on the steering wheel and i was able to assign up, down, left, right and get it to have the android auto respond. Need to play more but i think it actually goes android wide. For example i think the down button on my steering wheel was sending page down to the chrome browser i had open on the box. Pretty cool stuff if they expand that.
Hi all!
Recently I had a few problems with my MTCB-MD, but I managed to install new Android OS via PC and RK Batch tool. I still have a problem with a POWER BUTTON (and all buttons on the right side). Definitely the problem is MCU version. Stock was MTCB-MD-1.83V but since I updated it with MD-2.67 there is a problem with buttons, POWER BUTTON acts like HOME button and buttons on the right side (EJECT, MENU and BACK) are not working at all. I have tried to change a keymap in factory settings but buttons are still not working.
Question is: Does anyone know where to find MCU version MD-1.83V (MD-2.08V is oldest I could find) and is there any way to flash it from PC ( since POWER BUTTON is not working therefore I cannot make any selection in Recovery menu)???
THANKS IN ADVANCE!!!
Is it possible to flash MCU MD-2.08v with ADB, or maybe simulate power button key with adb or some other software?

No - the MCU has nothing to do with Android, but you can connect a mouse to your unit and do it that way.
Thanks @typos1! I figured out, but forgot to post
Last year my GF bought me Corto WKB-01 for controling PC when watching movies etc...I tried it on headunit and it works. In recovery i was using arrows to navigate and OK/ENTER key instead of POWER and managed to install MCU version MD-2.08V but POWER button is still not working. Definitely if I don´t find factory MCU 1.83V I am going to install in my car wipp switch on ACC line to keep HU off when I need only engine running or steering wheel unlocked....

It is strange it does not work, have you tried contacting your seller and asking for the MCU ? Have you tried different key maps with v2.08 ?

To be honest I didn´t tried other key maps, I´ll try it today. POWER button now on home screen acts as MENU button, and in the apps as HOME button (Previously it acted as HOME button on short key press, and on long it was opening navi app).
Unit was bought used (I broke my rule about not buying used electronics) for a more than a fair price (about 110-120$, unit was old about a year and dude I bought it from was 10km far from me). I´ve tried on net to find manufacturer but for MD someone say it´s Rhythm Audio (no info about that manufacturer on the internet) and someone say it´s unknown. Only sure thing is that it´s from China and it´s not any of the other well known unit manufacturers (JY, KLD...)... Anyway, my mistake paysback, I didn´t run backup of original Android and MCU before update But definitely if i don´t fix it I will install a separate switch.
I had a problem few months ago while servicing my car suspension, I had to unlock steering wheel and HU was running on all time.
The other reason I need power switch is that HU draws a lot of power from the battery. Since I have TDI it draws aditional power from battery for heater plugs (especially in cold days). In a combination with HU automatic power on via key, I am afraid that I will soon kill the battery.

No, you didnt make any mistake, its a good unit for a good price, I have heard of people with similar a problem who bought their unit new.
The problem is that we do not have many MCUs for this type.
It is impossible to back up the MCU so you made no mistake there either.
And also, most modern electronics are from China, whatever badge they have on the front (the iphone is made in China for instance).
An extra power switch is a good idea anyway, but you could also try remapping the buttons using an Xposed module, you could also try another ROM that may make your buttons come back.
Another thing you could try is upgrading back to v2.83, somehow this make make the buttons work correctly, I have heard this working before. And have you tried the "touchmap" option in factory settings ?

No, I didn´t tried touchmap because, but will. Also, I will update agaon MCU to v2.83 because it makes HU with latest Malaysk ROM work more stable. Swich will be installed soon, along with switches for aftermarket seat heaters, just to find the right place on dash. Thanks man for your time and patience, hope it will be ok.
No, I didn´t tried touchmap because I was not sure that it is related with hard keys , but will do.

Good luck, if going back to v2.83 doesnt restore your buttons, hopefully remapping them will
I just bought a PX5 unit, which seemed to be working perfectly until I finished installing it into my car and now it has become unresponsive with a black screen and a yellow rhombus with an exclamation point in the middle (unable to upload image as new user).
If I turn off the ignition, it will turn the stereo off and the android screen briefly shows before going into sleep. None of the buttons are allowing me to get past the screen and in to android. The reset button seems to do nothing, android is definitely running in the background, just unsure as to why this screen will not close. Any ideas?
Hi, I think I saw a yellow rhombus with an exclamation point when I was installing my radio and rear view camera was not connected to the radio. I think that it is a warning about missing video signal when radio is displaying live feed from a rear view camera.
So, one explanation for your issue could be that the radio thinks you are reversing, and the rear view camera is not connected to the radio. If I understand it right, radio can switch to rear view camera display mode based on two conditions 1) canbus information 2) +12v trigger signal.
For the condition 2), you could check that nothing is unintentional connected to reverse detect wire. If that does not help, then you could perhaps try to disable reverse view feature in the configuration menu before installing the radio to the car and/or find a working canbus configuration settings.
Please notice that I'm a beginner with Android head units and your problem might well be something totally different!!
Thanks for your reply. Some of your post seems to relate to my issue definitely, I think it is linked to the rear view camera which is currently disconnected. However I am unable to get into any configuration options. None of the buttons/resets I try get me past the exclamation screen, I can only see android once I turn off my ignition when it tells me it is closing down. None of the various reset button combinations seem to do anything with my head unit either, can't seem to reset it properly. Its strange, I will reattach the camera tomorrow and see if that brings any joy. I don't know anything about this stuff myself but I am wondering if I did something to the head unit to brick the non-android side somehow.
Edit: Unfortunately reattaching the camera did not change anything.
Update. I have managed to find a way in to the Android side if I connect my phone via bluetooth to the stereo, it then lets me use the split screen function via the top bar menu to put the warning screen other screen to the side, however whenever I touch the screen or attempt to use the android interface, my stereo goes back to the warning screen, none of my inputs via the stereo buttons or the touch screen seem to be registering with the Android side? Very confused. I have also tried as many button combination resets I can find and I have not been able to successfully get into the recovery menu, or any change except rebooting.
Was your unit professionally installed?
Also, what did the re-seller suggest when you contacted them for support?
No the unit was not professionally installed. I am not sure how I've become stuck with the problem. I made some minor changes in factory settings but nothing I thought would of caused this. The seller is yet to respond and its been a couple of days, but I have requested the hardware reset methods for this unit or any other solutions.

Check the reverse wire on the back of the unit...if necessary disconnect it to ensure no reverse signal is received.
If your unit can boot into android normally then you will have to figure out why the reverse wire is receiving signal .
Check your connectors to avoid any of them to be loose.

Everything has been disconnected from the unit except the power cable to car and and canbus, from what I can tell nothing is loose. Unit will not boot without the canbus box whatsoever, not sure if that is meant to happen.

Yes, canbus decoder need to be connected for power up the HU. If you dont need the decoder box you need rewire the harness.
I think I am going to have to request a refund and return it. Still no reply from the reseller and I am not sure what else I can try, everything that is not needed to power it has now been removed. I can't send links or else I would update the thread with a video of the touch/physical buttons being completely unresponsive even when I manage to get to Android. The unit has definitely developed a fault and I am unable to reset it. Admittedly it could be my fault somehow as it was working for the first few boots, but unless they give me something to try I am just going to have to send it back.
Quick bump. Has anyone got any further ideas? I bought off Aliexpress so contact with the seller is slow and painful, they do not seem to understand the issue and just keep telling me to disconnect all wires and reconnect. Which has been done many times. If anyone wants to post a link to the video for me I would be happy to send them it privately.

I would start a dispute with them. I had a device that they sent with similar problems and plenty of issues, which they would not help with or would not understand. Best option is to dispute to get a new device or a full refund. Could you send the video?

Yeh I have a dispute open currently, just was hoping it would inspire the seller to actually offer up a working way of resetting the device. Had to add link below seperately as needed to be ten or most posts.

The stereo defaults as the warning image black screen and I can only get android up using the multiwindow button with a long press. Then the android side will not register any input and will keep trying to put the black screen to the front.
Update: I have been told by Aliexpress I can have a partial refund and keep the unit, or a full refund if I return to China. Anyone have any ideas how I would go about resetting the unit if I took the partial refund? To be honest I think my only option is to return it and get the full amount back but any ideas would be welcome! Shipping to China and awaiting a refund is going to take weeks, would rather just get it working if possible.
deano35: any progres? I have the same problem as you. This is my post from PX5 MTCD/E Head Unit Discussion Thread
" Hi , I have https://s.click.aliexpress.com/e/DtwdJIt its px5, Mtce_gs_v2.90c. Now I have a little problem with rear camera. I bought reverse camera and tried to connect it into front camera input(I was curious how it would look like) and since then its stuck on camera view. Even after disconnecting camera. Only solution was disable "prohibit reverse" in factory settings menu, but with "prohibit reverse" disabled is obviously not showing reverse camera when I gear the reverse down. Everything is shown in this video. https://photos.app.goo.gl/XbYUHApzT8qTezkq6 Thanks for any advice. "
Take a look on the video, its similar as yours.
Hi guys,
I just bought a car unit android 8, but the screen sometimes (90% of times) looks flipped left-to-right. Sometimes is also flipped upsdide-down+left-to-right.
And sometimes I get the screen working as it should be, flawlessly, until I do not restart the car.
The defect appears from the beginning, right from the initial logo, and it remains also if I try to reset the unit. Also when I get the "boot" text menu, it appears flipped as everything. (edit - in addition, the touch layer still working in the right way, so I cannot easily understand what I'm touching on the screen, and this makes everything more complicate)
The unit is a px5, 4GB RAM, 8-core, the MCU is MTCE_XRC_V2.93_1.
I didn't already tried to overwrite the android files, because I'm trying to get some assistance from the producer. Anyway the product is coming from China, so I guess I will have to do it by myself. Until now, I rebooted, reset, cleaned, changed startup settings, and spent a lot of time in doing and re-doing all these tasks, but the unit still like at the beginning.
My question for you: do you think is it hardware problem, or can be fixed with a firmware update?
Do you have any suggestion, setting or trick in order to solve the problem?
Thank you in advance for your help.
Kind regards
It looks like a hardware problem indeed. The touchscreen 'digitizer' is apart from the display in the front. You could try if the ribbon cable inside the radio is firmly connected to the mainboard i guess. Otherwise i think a new screen..?
I will have the same issue with this same units. I write to selller , he send me a new spare part responsible for displaying the image.
I have the same problem. What is the spare part that solve this probem? Thank you in advance.
Got my Fold 3 a few days ago. Got is setup and plugged it into my truc,k and my Android Auto unit reads "No Device'". My Note 10 works fine but not my new phone. My headunit is a Jensen (like I said, worked fined with my Note 10). The Fold3 works find in my Nissan (Pioneer head unit) and my Edge (factory Ford Sync).

I am no expert here, but when I had a similar issue. I believe it is because I transferred everything from my prior phone to the new one. I got the same error when trying to pair my phone with wireless Android Auto in my Kia K5. My solution was to goto Google Play Services and clear the cache there. For some reason that allowed my phone to be found by my reciever. and worked. I didn't experince this with my new ZF3 but I did when I got my Note 20 Ultra last year. So try clearing the cache in Google Play Services.
Hey so try clearing the cache in the Google Play Services app. This worked for me when I had a similar issue with my Kia K5 going from Note 9 to Note 20 Ultra. I got the same error no device. This was going to a wireless head unit for AA. I finally figureout how to clear the cache in the Google Play Services app. Then went back to connect and it worked. Try this. It may work for the ZF3. Thankfully I did not have the same issue going from the Note 20 Ultra to ZF3. But this is what I would have done.
Thanks, man. I did that and to no avail. My phone is still not being recognized by my truck. When I press "Android Auto" on my head unit, I still get the message "No Device"
I'd flip cables for sure. Then I'd go to your setting when plugged in and make sure it's not set to charge only on the phone. Should be adjustable from the notification on charging.
I've having some weird issues with android auto and my fold 3. I've noticed when connected to android auto I often loose cellular data and it switches from 5g/lte/edge and no service. If I disable android auto the phone operates normally. Anyone else seeing anything similar.
Just a thought for OP. Did you happen to try opening Android Auto app in phone and checking to see if truck is an added vehicle and add if not?
The cable seems the most viable option. There is no option to select or deselect charging only, and Android Auto is no longer separate app. It is built into the OS and automatically opens when the phone is plugged into a headunit and there are no options to manipulate. The pain is that the dash has be pulled out to change the cable so I'll have to research a certified cable.
Did you buy chance to to settings > advance settings > then use Android auto there? Not sure if a setting in that will help. When I open it it wantsto attempt to connect to vehicle

When I go there, I get the button to connect to a car, but when I plug the cable in, nothing happens and the head unti still displays no device. I'm thinking that I'm going to have to remove the dash and change the cable.

Ah well unfortunately don't no more than that, just knew I saw an android auto option in there. My car doesn't support wireless and haven't tried the wired part yet to see
Well, removed the dash and head unit and changed the cable. I tried a Belkin USB-C certifed cable and even the known working cable from my other truck, and got the same thing.
On the phone I get the notification to stop my truck and apply the parking brake to continue and on the head unit I still get the notice of "no device" when I press the screen for Android Auto. At this point, I'm hoping I don't have to change my head unit to get this setup to work.
Weird mine worked just fine.
Did you make sure everything was updated
Yeah. I called Jensen they say it's a phone problem, Samsung says it's a Jensen problem
Got an email from Jensen customer service. My HU uses a bypass to allow certain functions while my truck is moving. I installed the HU myself and also installed the bypass. Jensen engineers found that I need to disconnect the parking brake wire from the bypass and connect it to chassis ground. I did that and was able to connect. I'm so happy to be able to use my phone in my truck.
