Prevent autostart of last app? - MTCB Android Head Units Q&A

Hi guys,
I am using a Joying unit with @Malaysk ROM and

The best way I know of is to quit your current app before you shutdown. It's a pain and a hassle, I know, but that tends to do the trick sometimes.

Thanks
Yes I know, this works sometimes.
But it is not a real solution
In the head units seems to be something different than in our phones.

Actually the head units never shuts down completely as a smartphone, because there is always some power supplied to it from the car battery, and therefore some dedicated memory can maintain the last active selections (radio station, apps, music, etc.).
To reset that memory, the power should be completely removed from the unit when turning ignition off.
If you wish to permanently disable the auto resuming, this can be accomplished disconnecting the relative wire in the harness.

Android Eonon GA2114 - unable to shutdown fully? / also 'preparing SD' for USB stick

Hi,
I have just bought and fitted a Eonon GA2114 Android unit
I have one or two issues please, and would really appreciate some help
1. When I hold the power button to shut the unit down, it says 'shutdown' for a second and the screen goes dark. When I power it on again it comes on immediately as if the stereo is switched on all along, just with the screen dimmed. (It does not boot up Android) - I should mention it is fitted into a campervan running off a leisure battery. Shouldn't make any difference I'd have thought but it is a permanent battery connection (No ignition on/off) is this a clue? I wondered if it was to do with the ACC wire if so?
2. When I do 'wake up' the Car Unit it seems to take quite a few seconds or so to 'prepare the SD card' - this can only refer to my permanently connected USB drive full of music (Via the rear of the unit) - surely this should be ready to use immediately the car stereo is on? It means I can't just switch on, and play music. Any ideas please as it is very annoying?
3. A brief one, what is the best locally stored Android music player to use please? for car use that is?
Many thanks for your hep
I must admit I am a little surprised to have no replies so far? Anyone pls?
Hi, is there anyone that can help me with this please. many thanks?

Does the unit come with root, if it doe you could download a reboot app, most require root to function.
I don't believe these units actually shutdown, just go into standby mode, you cab check with the ENON techs.
No root as far as I am aware, a good idea otherwise thank you. I am still unable to fully power off (Or reboot) the unit. It seems to draw a lot of power and will drain the Leisure Battery for sure. I have emailed Eonon a few days ago, but not heard anything back. Not sure if they are active in any of the forums for a quicker response?
As for the USB Memory Stick with music on, I am still having the problem of 'unexpectedly removed' and 'preparing SD card' each and every time the unit is first used / turned on. Any ideas please as it's driving me bananas! thank you
I have the same unit and yeah it says powering off and it isn't powering off at all, it is even still connected to my phone via bluetooth when it has supposedly powered off!

Thanks for your reply, that is interesting. I have had two replies from Eonon so far. As I thought the ACC cable may be the culprit.
1. Unit can not shutting down completely
Please check whether you have connect the ACC wire always on BATT? If yes, this unit cannot turn off completely.
Please find the ACC control wire on the Fuse box location, then connect the ACC wire to the ACC control wire, the unit can turn on and off via key.
2. If you use the USB Memory Stick to play music? If so does yours have the delay issue as well? )Answer from Eonon copied below so far:
Yes, it will show message when you plug in or plug out SD/USB, this can not change.
But if it shows some error message that make the SD/USB would not work, would you please take a picture to show us?

I have the ACC wire connected correctly as when I turn the ignition off the stereo acknowledges this and turns off/powers down but that function is hard wired supposed to turning the unit off at the on/off/volume knob (while the ignition is on). Their answer is just avoiding the issue as the unit turns off fine with the ignition, it doesn't power down like it says it is when the ignition is on. I just turned my 'off' with the ignition on and could still connect to it via bluetooth....
I can't comment on point 2 as i've yet to rig my amps up and play any music!

Mmmmmm, thats not quite so good then. I was thinking that it might be the ACC as mine is running from a permanently 'on' Leisure Battery. I will probably pop the stereo out and have a look in the next week or so as I can't really change the battery situation (The idea is so that I don't run the starter battery down as it is a CamperVan)
I must say though that I am impressed with the sound (I have been testing PowerAmp, and PlayerPro and they both look and sound STUNNING, the standard player kept skipping for me at least)
I'm still looking into the other thing (Memory Stick) it works, but it's annoying really
I just got my unit yesterday and installed, so far very good device.
I noticed there is a setting in setup to delay shutdown for 30 seconds, and up... Maybe you are not waiting long enough for complete shutdown.
If you had the ACC wired to Battery, the unit screen would not shut off (i think).
ACC being connected to a permanent live compounds the problem as whenever ACC is live i.e ignition turned on, you can't power the unit down at all even though holding down the power button it clearly states "shutting down" when in reality it merely turns the screen off.
Thank you tiff_lee, I think that is exactly what happens in my case (Just the screen goes off)
It is draining my 12v battery rather quickly! If I was to disconnect the ACC cable will I still be able to power it on and use normally? (In my case the car stereo works from a campervan leisure battery. The idea being that you can have the radio on at any time without the ignition having to be on. Also it doesn't drain your starter battery at all)
Many thanks
ACC is accessory power. Accessory power is only powered when a key is on. If you don't have it wired to a ACC source then it won't properly shut off. Wire the ACC with the power wires and put a toggle switch between the battery and the power wires. I would think that would solve the problem.

If I understand your first post correctly you have the ACC connected all the time so yes the unit would effectively be on all the time hence the power drain. Leave the main power connected at all times as this also powers your memory, connect the ACC wire to a 12V+ supply via a toggle/selector switch and just turn it on (via toggle switch) when you want the unit on.
That aside though it doesn't change the fact that the unit does not power off when it says it is.
Hi
Been following this thread and having same issues I only have mine connected by the iso adapters and the unit doesn't seem to shut down fully,have had 1 flat battery so far after not using the van for several days on recharging battery and turning on it showed full start up screens.
Other issues are not being able to turn off the radio once turned on apart from in settings "force stop app"
No voice guidance in the Sygic GPS app.
Someone asked for a good music app,try N7 player,also Smart launcher is very good ,have it on all our Android stuff.

I have bought a Pumpkin KD-C0224 Android car unit and it's working great.
1. Have met the battery drained issue before and the Pumpkin seller suggested me exchange the "ACC" and the "B+" of the iso adapter.
They explained that the “ACC” and the “B+” of my car is opposite to the iso adapter, so I tried and it worked.
2. Maybe your USB Memory Stick is beyond the unit can support, or you can try other USB device with less than 32GB to check.
3. I have Spotify on my unit and its great, I think.
Hello,
someone did you solve this problem? I use the same multimedia Eonon GA2114 and have the same problem .In the moment extinguish my car out inscription 'unexpectedly removed SD card' Just to give contact and back contact without starting the engine again my written 'unexpectedly removed SD card'.
After starting my written 'preparing SD card' and starts from the first song. I'm tired just listening to the same song Please if anyone can help.
I have a very similar problem which has only started to happen recently on my Eonon head unit.
The problem is when you turn the unit off it shows a message saying "storage unexpectedly removed". When you turn on the head unit again it has to remount the USB drive and it starts playing music again from the beginning of the MP3. It never remembers the last play position of the MP3. This happens on various makes of freshly formatted USB sticks. Its very annoying....
I have done a full factory reset, disconnected the power and also re-connected all the cables from the back of the unit - but this did not resolve the problem.
Not really sure what to try next...any suggestions would be very much appreciated!

Wifi Not Enabled after Reboot - 12 Hour Time setting Resets After Reboot

Ok, I installed the new Joying 10.1" VW head unit in my car the other day, and it's working pretty good, however I'm having a couple of issues. I installed Malaysk's ROM onto it and still working through setting everything up the way I want it, but I'm having 2 issues I can't figure out, and they are driving me nuts.
Wifi: Whenever the unit reboots, the WiFi is disabled. I have to manually re-enable it every time.
12-Hour Time: Every time the unit reboots, the time reverts back to 24-hour time.
Anyone know what I can do to fix these issues? Getting rather annoying having to switch them every time the unit boots up.
Thanks

Sounds like the 12+ and ACC connections are swapped.
Thanks for the reply, but the unit is switched on Via Can-Bus. There is no ACC wire. It powers on and off just fine when I start and shut off the car.

Then your 12+ is not constant.
Yep it is, verified with a volt meter, 12volt constant stays hot, even went out and checked after my car had been off for over an hour just to make sure... I shouldn't have said there is no ACC wire, ACC is supplied by the Can-Bus adapter.
As far as the wiring goes, I'm confident all of that is wired correctly. I used to install car stereos as a job for 5 years, and this is the 3rd head unit in this vehicle. I'm an Android enthusiast, and definitely know my way around the system, even though this is my 1st Android head unit I've dealt with.
The 12-Hour time issue was happening before I installed the ROM on it, but the WiFi issue didn't start until after I installed the ROM.
Ok, thats a puzzler then. My observations have been that wi-fi will turn off and 24 hour set every time power is lost on the 12+ line. It seems independent of rom used, would happen on the stock rom and on a older version of Malaysk's I'm currently using.
Well, for whatever reason today the settings never reverted back. I don't remember changing anything, but I did go through every single menu and sub menu in the settings section. Oh well, fingers crossed everything stays set, because this head unit is perfect for me now!
I have the same issue + no bluetooth. I have a YINUO 1024x600 Quad-Core RK3188 and it's doing the WIFI OFF, 24 HR, NO BT.

Problem with Radio stock app that doesn't keep channels and other little issues

Hello all!
I recently bought a android head unit that runs android 5.1.1. (MCU: MTCD_MX_V1.73_1, Kernel 3.0.101+) I have several little problems, one of them is that the radio app that is provided doesn't store any channel that I save after a turn off turn on. Is it something that can be solved or the best is to use another radio app? Maybe you have good examples?
More generally it seems that every-time I turn OFF, it loses the time (it goes back to some random date in 2012 at 00h00).
The GPS also seems to loose the ephemeris and needs to download them every-time, I get a fix after 10 to 15 minutes after turn on is it something normal?
Any help would be much appreciated!
thank you!
What kind of vehicle did you install it in..?
You probably need a canbus harness for your car or run a accessory power from your cigarette lighter + wire..

HU doesn't wake up ramdom

Hi,
I installed this HU in my car a month ago and I still have not gotten it to work properly. My main problem is that the unit reboots randomly and does not turn on again.
I have tested the reset button and checked all the wiring. I have connected the 12V direct battery and the adapter for the steering wheel gives me the 12V ACC.
It seems that the radio goes into some form of protection until it suddenly decides to restart.
I really do not know what else to check. If I modify some parameter in the factory settings, it asks to restart, it only shuts down but does not turn on.
Yesterday afternoon it worked correctly but this morning it has not started.
any ideas?
These are my specs:
Car: Alfa Romeo 159 (2012 year)
HU: Xtrons TE706PL
MCU: MTCE_GS_V2.88_3
steering controls: Connects2 CTSAR002.2 + CTMULTILEAD.2 Patch Lead
I'm experiencing the same issues with my PX5 / CSN2 headunit from Klyde. Sometimes the HU won't come out of standby, the screen remaining black and buttons not reacting at all (but with LED backlight). If I had FM radio before turning off, it will start playing audio only in the background. Turning off the car engine triggers a restart, as if it entered some unrecoverable state.

First...update the rom and mcu to the latest available
Try
Second...disconnect the connects2 and use the unit without that canbus to ensure there is incompatibility issues. Try

Well, in my case the unit doens't start, nothing, no led, no sound... I think the problem is that the unit is not able to make a cold start after going into deep sleep

I can't update the frimware if the device doesn't start...
I'll try, but it is not easy because my car doesn't have 12V ACC so I need the connects interface to get the power.

To test, I would do this.. Connect the acc direct to battery.... The deck should turn on.. Reboot the deck while it's on. If it boots back up... Then the above poster is probably correct. Your module is not working correctly and not giving a proper acc signal.
The unit was connected with ACC wire connected to the Connects2 adapter. But yesterday I connected the unit directly to the car only the wires; ground, 12V battery and 12V ACC. The device started and worked fine. Turn off the car and five hours later the device didn't started. Today 20 hours later the device doesn't start either I tried to disconnected everything and connect again but the problem continue.
I think the problem is, the device is not able to do a cold boot after to turn off the radio. How to do a factory default reset? maybe this fix the problem.
I connected the device to direct battery and the first time worked but now it isn't able to start....

my SWM8802 radio stopped turning off when I remove the vehicle switch

Regards,
I tell you what happened, about two years ago I bought this unit and everything worked fine, in fact, quite satisfied with the cost / performance ratio, unhappy with certain details that I have read in other threads for not being able to connect my ELM 327 to the radio bluetoh, annoying noise of the internal processes of the radio, among others.
Three days ago, my wife connected a damaged cable to the usb port of the radio to charge her phone, at that moment the radio went blank, as in short, when I realized I disconnected the cable, the radio restarted and everything seemed to be Well, when I got home and turned off the car, the radio as usual also turned off, but with the difference that the LEDs on the buttons were still on and the annoying noise from the internal processes of the radio was heard (it was not turned off totally). Another problem is that the physical buttons were deactivated when turning on the radio again, for them to work I have to reset the radio, but when turning off the swich and turning it on again the buttons are deactivated again.
To rule out that it was a software problem, I tried to do a factory reset, I installed several updates that I found in this forum and in a Russian one, in principle the updates complicated my radio more, leaving the mirror mode, etc. I insisted and got a proper firmware and it was her again, but with the same problem I had been telling them.
I decided to open the radio and found this:
It consists of two board, one where the tablet is concentrated and another where the amplifier, outputs, etc.
As for the amplifiers and the output, etc. I saw that there is a big stain, at first glance it seems that it was the filter that spilled, in my opinion (I don't know much about electronics) it looks like Flux or a glue that was left at the time of its assembly.
On the tablet board there is another smaller spot, it seems burned, but it is the same substance as the other board.
My questions,
Will the problem be physical, the filter exploded? (does not look bloated or anything)
It will be software, should I reinstall the software through the computer and not through a ZIP file update?
What part of the engineering menu could modify the parameters to try to solve?
I await your diagnoses and possible solutions, thank you very much.
Sorry if reading this thread is confusing, but I use a translator, English is not my language.
