Just installed a Joying:
. SKU: JY-UL124 . Quad Core Android 5.1.1 Lollipop OS Capacitive 7" High Definition for Universal Double Din . CPU: RK3188 1.6GHz Cortex A9 Quad Core, Resolution 1024*600. RAM：DDR3 1G, 16 GB memory
To my 2014 Australian Hyundai Elantra.
I waited to get the latest HU from Joying that has an unrated mother board and USB/ Comms board. With Lollipop 5.1.1. the unit performs very well with none of the problem previously mentioned on these pages. The internal and external mics are clear and the Bluetooth systems are perfect. Unit has been rooted and I don't seem to need for apps so I won't changed the software.
The dimming for the button and the screen to follow the vehicles rheostat was fixed by making a circuit to invert and amplify the rheostat output to the HU ill line. Work's well, Kudos to the guys at the Subaru forums.
I had one bug fixed by Joying when the GPS nav was muted whenever I plugged in the DVR front camera. Joying quickly sent me a link to re flash my firmware and the problem was fixed. I have them currently looking into a bug when I view the DVR input shown on the HU I get lots of flashing to the screen in all pixel settings. I have been told this will be fixed in the next firmware update soon.
One problem that I can't solve is when I try to use my vehicles Multimedia Jack located in my center console. There is a Aux and USB jack there. All wiring from console to HU is complete. If I connect a USB stick to the Jack in the console then then HU struggles to connect and gives up. If I interrupt the USB plug and socket behind the HU then I am able to use the USB correctly. Looking at the car wiring diagrams there is a amplifier cct behind the Multimedia Jack supposedly to amp up the USB to HU. Doesn't seem to work?
Any ideas appreciated.

If anyone has any ideas on
i have nothing to add, other than interested to see what the result is. Are you saying that your car comes with a built in hub in the console, and you are trying to make that USB port in the console work to the Joying head unit? my vehicle is similar, and I would like that to work as well
Update
Yes I have a console hub I guess.
The book calls it a multimedia center. Just an Aux port and a USB port or Jack in the tidy bin in the center console. If I by pass the Jacks and directly put the USB stick into the USB tail from the radio then it works fine. When I plug into the console port it tries to read it and fails. The HU then reports a read fail, have tried other known working USB sticks.
I have inspected behind the console jacks and found a cct board attached to the Jacks and then to the car wiring. From looking at the diagrams of the car previous to mine I see a cct board containing what looks like an amplifier. Tracing the car wiring to the radio input connectors seems to be OK and the wiring correct. Voltages at the radio connector are right in that there is 5v +ve, negative - earth and the center pins are data as they should be.
The console Jacks

The wiring for same (mine is same but more complex)
w.hemanual.org/multimedia_jack_schematic_diagrams-2036.html
Really bugs me not to be able to access that USB input Jack esp as the radio is a great unit.
You need to post this question in the MTCD (Lollipop) hardware thread. This thread is for MTCB (KitKat) units. The hardware in the MTCD headunits are very different than the MTCB headunits.

Yes, the MTCD thread is for the headunits with 5.1.1. The hardware changes and software are different. Send one of the admin a message and tell the why you need to get the permissions to post. I had to do that some time ago. Just make sure you follow the rules when post or you can have you account suspended or whatever the moderators deem necessary.

Ok thanks for that. I don't seem to be able to find how to "Send one of the admin a message" Can you help?
Just for info, there are both MTCB/C and MTCD/E Lollipop units.
hello
a friend of mine have mtcb KLD6 head unit
he ordered USB camera from ebay:
http://www.ebay.com/itm/262717408162?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT
the head unit a lot of times cant initialize the camera and a reboot is needed.
when the camera does initializing, the picture is mirrored right to left and left is right
is there a function to fix this ?
Even, I am getting mirror image for front camera.
I have MTCB kld6 and camera is connected to AV IN.
Earlier it was working fine, but rat bit my camera wire and I had to replace front camera.
Any solutions please
The Dasaita V600 does not switch on the rear view camera until the multimedia is turned on. the front parking camera displays immediately. the rear parking camera motor does not work until the dasaita v600 main screen is turned on What could be the reason? this is very bad. the car is running, the rear camera does not display images for 35 to 40 seconds until multimedia is turned on. the front parking camera gives the image immediately without waiting. There is no such problem for the multimedia of other brands. I thought of it as a software
Help Me
does every user have the same problem? the park camera will not work to start the car and move back and forth immediately. Wait for 40 seconds to turn on and then move on. this is ridiculous.

Faced this issue on my Dasaita HA2021-V600 but in my case a little work on canbus wires solved the problem.
Looking at connection diagram on top of your head unit you need to search a wire named "Reverse", in my case the wire the nr. 2 in orange color.
This wire in directly connected to canbus box; cut that wire and connect it from head unit side to +12V from reverse lamp.
After that you will see immediatly camera images when you put your car in reverse gear.
Now my turn for a question: what type of front camera are you using and how you have connected it to head unit and which harness you have used?
Hope my suggestion can help you
P.S.: Make that at your risk, im not responsible for whatever damage on your unit with my "mod".

Hello. To attach the front camera to the car, first go to the factory settings. Activate the camera in the last section there. how many secs you want to see. then buy and install any front rear camera.
Place the cable in the D. aux in glass on the device. now the front camera will help you when you leave the back cabin during each parking.
Thanks for your reply, but i dont understand what you said in:

Hi,
I am having quite the same probem with my dasaita.
when I switch to reverse I can only see a black screen with the green guides and a sort of yellow alert.
Can you tell me the color of the +12V reverse lamp wire? did you find it behind the unit or you cought that +12v from the reverse bulb behind the car?
thank you
Mirko

If you are facing that issue you simply need connect the yellow RCA cable from you rear camera to the right RCA connector in your head unit, you dont need perform any modification on HU wires; that RCA wire is usually labeled CAM-IN or Rear-IN. Check you connection
Also if you connection are OK the camera is not supplied with +12V and you need use the wire that come from the reverse lamp

I tried that already. I think it's a problem with the cables. I contacted the Dasaita Support and suggested to work on 2 pins of the canbus.

Not a probl with canbus. The only problem that canbus can do is "not switching on reverse gear". When you see the yellow "!" mark on screen mean that unit is not receiving video signal from camera.
Try this for checking the camera: connect the yellow RCA cable from reverse camera to AUX-Video IN harness and use AVIN app if you see images the camera is OK if not you need to check camera connections.
Cable 2 from canbus trigger only the "rear view" if the unit is not switch to reverse input.
What are the canbus setting on you factory setting menu? you car is an E46? what type of main connector are you using 17 or 40 pins?

ok will try.
I don't know my car type..it's a Nissan Qashqai
problem solved
problem solved. the original camera was removed and replaced with another camera. electric power was taken as 12v from parking light. As the original camera was 6v and powered from the unit, the rear camera was not working until multimedia was turned on. everything works fine now
Max 6 wrx rear camera
I am having the same issue on my 2018 wrx limited. When I put it in reverse I get the yellow ! Or see a black screen with the guides. If I go to the AV in , I am able to see the reverse camera image. I have the Dasaita Max 6 (px6). Any assistance would be amazing!

I tried that and tried every combination that I could think of with the Various RCA cables - just the yellows, all the rca connections, the different yellows. I think it may in an issue with whatever wire from the car that triggers the camera when it is put in to reverse.... I read somewhere that the harness provided from Dasaita may have an empty pin hole where that wire should be. I am not savvy enough to know. Thanks for taking time to try and assist. Any other tips to try? could this be a voltage issue?

I dont understand this. I also have android PX3, Back camera works as I put in reverse. Connected front camera tu AVIN, settings set to "enable front camera for 15sec after reverse". But I only see black screen.
When Manually open AVIN I see front camera, how do I enable this?
Thanks
Hello,
ich had also problems with the rear cam and that's what solved the problem in my case!

Hi there everybody,
I recently noticed my PX6 unit doesn't see any of the front / rear cameras. With all wires connected the f-cam app shows the orange triangle (no signal) for both front and back cameras. The same happens if I give a 12v signal to the reverse (pink) wire.
I never got to install the backup camera in my car but I did bench tests with a power source and had the cameras working when I first got the unit. Now, a few months later, the cameras simply don't work
I tested with 2 different cameras and also with a DVD player and none worked.
I even opened the unit and checked the motherboard to see if there is a fried circuit or IC...and saw nothing. The video inputs lead to a IC labeled "FMS6502" and the signal gets to it through a 75ohm resistor and a capacitor which both look okay.
What can it be?
Please give me your opinions on this as it drives me crazy !
Thank you!
I would guess your headunit is not providing the 12 volts to both cameras
Hi , I remember your Fcam app requires you to connect your front view camera to your f cam video input and provides thru another lead a 12 volt output in which you can conect the power for both your front and rear camera. If both cameras dont work most possible the radio is not providing the 12 volt output .

What. You've just said, connect the front and rear camera and the +12v feed. The headunit doesn't provide a 12v output for the cameras.
Not surprised at the guess, these topics generally are guessing games.
I'd suggest finding a skilled car audio tech or auto electrician. That's not meant to be an oxymoron, seriously
Hello
Today I installed my back up camera to my PX5 6.0 Android unit with the Rockford fosgate system. The Android unit says it's MTCE_HA_V2.85_1 and I wired the wires to my reverse light power and ground and plugged in the RCA cables but I didn't do anything with the wires attached to the RCAs. When I put my car in reverse the reverse mechanism triggers but instead of the video from the camera it's just a black screen and the parking lines. Any help would be greatly appreciated.
Check the power supply of the back up camera and the yellow RCA connector. Connect the RCA connector that labeled CAM VIN but not AUX VIN.
Hi All
I bought a Kunfine head Unit and a aftermarket reverse camera. I hooked up the reverse camera to the reverse light and ran the cable to my Kunfine android 10 head-unit. My Head-unit does not have a dedicated reverse camera Socket for my RCA cable coming from the reverse camera. So I plugged it in to the CCVB and i got an Image, but i have to select AUX on my head unit to see the image from my reverse camera. The unit also dont have a dedicated wire to fit to the reverse trigger wire. Can anyone tell me what i must do in order for the reverse image to come up on my android unit as soon as i put my car into reverse. There are no "back" or "reverse" wires on my head-unit canbus... Please help. I will really appreciate it.
Thanks
