Can anyone help me. I purchased a 12.8 tesla style unit. MCUVer says RL7Ac_KLD9M_dsp-F031 -V1.01.009CYPR. Everything was working fine until one day i got in the car and nothing played from the speakers. Unit was working fine. Then The next day the screen went black. Now if the key is in Acc the unit works fine, plays music but the second i switch key to on the image on the screen gets frozen and then fades away. I conacted the company and they want me to send the unit back for repair but i checked prices and its $100-200 to ship back. thats 30 to 60% of what i paid for the unit. Should I just cut my loses and go with a different brand?

My new head unit arrived the other day. Ordered it from AliExpress and it took less than a week to get here. I sought out a replacement because my previous Android head unit (Eonon GA5153) was having issues. It performed great for just over a year without any issues. A couple weeks ago my car battery started draining and I couldn't figure out why. It wasn't until I went to grab something out of my car at night that I realized the lights around the unit were still illuminated. Not only that but the fan was still going. I searched thread after thread and I couldn't seem to find an answer other than installing a toggle switch on the accessory wire. I found the Witson 9 inch unit for $245.00 and decided to give it a shot. After unboxing and wiring everything up I realized that the radio trim wouldn't go on because the edges were somewhat squared off in the back of the unit. It clearly isn't a perfect fit for my vehicle (2008 VW R32) but I wasn't going to let a small problem like some square edges prevent me from enjoying a new head unit...that and sending it back to China. I pulled out the old Dremel and used a sanding attachment at low speed and fixed the problem in less than 5 minutes. The unit looks great. Fits just as well as the Eonon did. The only issues Ive had thus far involve the unit not remembering certain things when its shut down. The LOUD beep that occurs with every touch has to be shut off every time I start the car. The radio starts up every time the car is started as well and doesn't save any of the pre-sets. The adjustments to the equalizer wont save either. If anyone could help me out with these issues Id greatly appreciate it! Thanks!

It seems like you have swapped red and yellow cables. Yellow should be always on +12 volt. Red is controlled via ACC, i.e. on when your starter switch
is in acc or running it supplies +12 volt. The yellow, always on, keeps the memory powered. i.e. radio stations are saved and so on.
[dormancy setting] - DORMANCY IF CUT ACC --> ON If you select a hidden setting to radio sleep after cutting off ACC,do not turn off the radio will remember your settings. It will be up to speed will execute and will not beeps when touching.
So i bought an android headunit a couple weeks ago, quite pleased with it, but a couple days ago the unit just went totally unresponsive, black screen no buttons ect, looked at the crude instructions to find a reset button on the front.. pressed it and it rebooted fine but now, none of the buttons work.. i cant turn it off, so i'm currently removing my negative battery terminal to protect my battery.. can anyone help ?
sda will not let me link the unit i bought.. but its sold by hizpo on amazon..
Regards
Dave
So I bought -what I believe- is this Android Head Unit over a month back (Apparently I can't post links yet, but if you search Amazon for "Car Stereo Touch Screen Bluetooth GPS DVD Double Din In Dash Sat Navigation Vehicle Head Unit for VW Volkswagen Jetta Golf Passat Tiguan T5 VW Skoda Seat Hands Free Call Free Map Backup Camera" the result is the item that I got. ) It worked fine once I got it installed, then about a week ago it started having issues (Screen would freeze, buttons unresponsive, and would stay like this until car had been off for some time. Still switched to backup camera on reverse.) I tried to go into settings and do a factory reset to see if that would fix the issue, but now it's stuck with a black screen and the word "Erasing". It still seems to be doing something because overnight the next time I come out the screen is on and it says, "Recovery 7.1.1 :failed to mount /cache (invalid argument)" I've tried several different button pressing methods to try and get to the recovery screen, but it just keeps coming back to the "Erasing" screen regardless of whether I use the Reset button or the Power button (held). I have a couple pictures of settings from the "Droid Info" app (because I couldn't find anything helpful in the settings themselves) that I took before I started having problems with it. So I'm looking for some help regarding getting it into recovery and/or finding out what I'm doing wrong.
Brand is confusing, roundabout on Amazon I found "Malanzs", but it looks exactly like and has the same Manufacturer # as the TMOTEC brand (DS02P051S01C0) and a lot of the pictures of the Malanzs one look like they photoshopped them from the TMOTEC pictures.
One of the things I was trying to find on my pictures but I don't have is the MCU version (apparently this is important for where I will get the most help with my post)
Any help is appreciated, thanks for your time.
I can't help get it working (it sounds defective), personally I'd return it to Amazon quick !

Hi Guys!
I bought a "Unbranded" Chinese head-unit (Sofia 3GR), thing is, the screen starts off perfect, everything works and displays perfect, then after about 5 minutes, white lines start appearing from the left of the screen, later growing over the whole screen.
Everything still works perfect, except this white "overlay" on the whole screen.
After a reboot, screen is perfect again, and the issue starts again about 5 minutes later. I've monitored the temperature, and it does not seem related.
Here is a video of the unit acting up:

Seller is not very helpful, anybody know what the problem can be.
Any help will be great!!

Most likely the screen controller or dry joint? you could buy freeze spray from electronics component shop and try spraying into the suspect areas. Then you could use a microscope to inspect for dry joints and solder it? Obviously these units are too cheap to take to a repair shop as the bill could be more than buying a new unit.
If no luck, you could sell it for parts.
had my joying sofia for a couple of years now and it has started playing up in the last couple of months
first problem was the screen becoming non responsive, fixed by following the soldering video
second problem was the gps fix getting REALLY screwed up when using any sat nav app, I put it down to overheating issues so had to switch the unit off and use my phone instead. not ideal
most recent issue has started over last 10 days or so - when the car is switched off and the keys removed the unit display stays on for approx 5 - 10 mins. It has no response and cannot be used, no presses do anything and there is no sound but the display is still "live"
I must admit i'm not impressed with the joying but it seems to be the best of a bad bunch where android head units are concerned as it has the greater community support
can anybody help?
Firstly, which Intel Sofia model & software version is it ?
Have you fitted larger heatsinks & fan for the main processing module ? This is especially important where the unit is mounted directly in front of the car heater.
For the shutdown, re-check the Joying sleep mode settings.
I had a Joying Sofia unit in my car till a few days ago. It started to slowly die after doing quite fine for over 2 years. Before it really gets on my nerves, I took it out and replaced it temporarily with a Coika PX5 unit. Seems that yours also slowly wants to make itself redundant...
It is absolutely normal that the unit remains on for another 5 minutes after removing the key. Yes, there is no audio output, and the screen cannot be touched. But one can fully use the unit from remote, e.g. via TeamViewer. This is how I noticed.
What it usually does however: turn off the display so the user does not see the Android screen anymore. This is no more working with your unit.
I do not know a specific solution for your problem.
I would try reflashing the unit, both MCU and Android. You will end up with a fresh unit however, because all of the Joying sw updates always wiped away all user data.

to clarify -
my unit is the JY-UL124N, purchased from german warehouse 14/03/17
for the last 2 years my joying has "gone to sleep" on the immediate removal of the keys, not only in my current vehicle but also in my previous one so I do not believe it has anything to do with sleep settings. The same problem occurs when I choose "switch off" from the pulldown menu
I do not intend to try and fit heatsinks/fans - I am of the opinion that should this unit need them then surely joying should have fitted them in the first place?
I do not believe it is "absolutely normal" for the display to stay on for 5 - 10 minutes when the keys are removed/switch off is chosen, it has never done it in 2 years of ownership, has only started to do it within the last 10 days and does not do it every time
I have reflashed the unit several times, both MCU and android. same problem
to be quite honest, this unit has never really done it for me anyway - after having read the countless problems other users have suffered/endured over the last couple of years I suppose I should count myself lucky that my unit has been relatively trouble free and the problems have only recently started to manifest themselves. In my own personal opinion joying have foisted a substandard unit on the public and then sat back while we all became unpaid beta testers for them - look at all the hard work surfer63 and others have done? for free as well I might add. I should have kept my parrot asteroid smart as it was a superb unit but then parrot dropped support for it and its apps with no prior warning hence my move across to joying
I cannot put up with this thing anymore, I have never liked the music player and radio tuner interfaces anyway - they are far too "busy" and distracting. The FM tuner does not work properly. The sound is poor. The bluetooth handsfree is terrible in that people cannot hear me properly during a phone conversation. The unit is and always has been incredibly slow and laggy. The music player has a really irritating problem in that it will always play the next track alphabetically, NOT the next track of the album I am listening to. The music player also cuts off the first second or two of every track it plays.
Please everybody be aware that I do not intend to turn this into a thread knocking joying, I am just voicing my opinion that after 2 years of ownership I have not been impressed with this thing so to that end this afternoon I bought a new alpine iLX-702D. I have had many alpine units in the past and know them to be quality reliable units. And the FM tuner RDS/AF will work, properly
