Weird issue here and I need help! And I think I may have somehow did this with settings but I've been through all the settings and can't find anything. Thinking of doing a reset tomorrow, but im scared to do that. If it doesn't fix the issue I may lose my mind.
Background:
I have had my OL-6666F about a week. After wiring it up in the car (a 2012 Sonata) the first few days were great everything was perfect. I didn't have a lot of time to mess with it beyond soldering everything up with a wiring harness. Thurs/Fri I had more time and played around with adding more apps, playing around with settings, and setting up the steering wheel controls. This is when the problem started.
Issue:
Any time my car is at a FULL stop the headunit screen goes blank. It's not off, it is on as I can see light but the screen is blank, all keys on the HU stop working, as well as the steering wheel controls. However, if I had the radio or iheartradio, or nav going... the sound will reduce but continue to play. I can't control the volume at all. The very second the car begins to move forward or backwards, the screen pops back to where ever it was. I even tried it with youtube today. Youtube would pause the video/sound instead of continue playing like the other apps. Soon as the app came back, I pressed play and it resumed like nothing happened. I've tried creeping forward, I've tried using neutral, and I've tried reverse. I've tried sitting with my foot off the brake and the car in neutral. Nothing happens until the car begins to move then bang its perfect again. Also today I turned the screen off by pressing the display knob which clearly turns the screen completely off. When I stopped the screen changed to the blank but on screen. When I began moving the screen went back to where it was before I turned off the display.
WTH could cause this? I cant think of any settings I changed which have anything to do with being stopped. How does it even know I am stopped!? GPS? I did not connect the "brake" wire to anything. It is covered in electrical tape.
I can take a video of this if needed. It happens every time I stop without fail.
Do you have a canbus harness adapter? Did you accidentally connect the reverse input on the radio to a parking brake/zero speed wire of the canbus adapter?
I do not have a canbus harness. I used a Scosche Radio Wiring Harness (021HY12B).
After yanking it back out a few minutes ago this is exactly what I did. I mapped the pink reverse wire from radio to the also pink "speed signal from vehicle" in the Scosche harness. WOW. I'm glad you replied cause it made me question myself. Works perfect now.
I'm going to be shaking my head at myself for a while.
I have one of the latest Joying 2GB Sofia headunits, don't think it really matters which one.
What I do not have is a reversing camera and as I am not driving a bus or heavy goods vehicle I don't intend to get one.
So my questions are
1. Can change or tweak something so when I put the car in reverse the screen doesn't change (I know I could cut the reverse wire to the headunit but I like the feature which reduces the volume when reversing)
2. If the above is not possible is there a way to remove the reversing lines which show on the black screen when I am reversing? I am aware that there is an option for this but if I disable the revering lines in the settings I get a black screen with green text saying "no signal" when reversing.
Thanks
Test the wire, maybe is defective
FOr me works perfectly with Opel Joying 2gb
I have encountered the same issue. I do realize that if I leave the car in reverse long enough eventually there will be signal. The weathet has became cold I am not sure if there's anything to do with it

I purchased a Joying single-DIN 6.2" head unit from aliexpress and am having two issues. When I first turned it on the display was completely scrambled. I let it boot & sit for a while, but eventually ended up hitting the reset button. I did that three total times, each time the display became (oddly) less scrambled. After the third, it booted up completely normally and I got to work finishing the install.
Once finished, I found the power antenna trigger was not working. No 12v from the stereo. I checked the fuse, then checked for power directly at the stereo connector. Nothing. I temporarily switched the amp-cont with the ant-cont wires, and the antenna worked but the amp did not. So, I'm 100% confident the issue is the stereo - not my wiring or anything else. The car happens to use ISO connectors, so there wasn't much wiring to do.
I dug around in the "developer" menu of Car Settings and found an entry I believe says "Antenna always on" or something like that. I tried enabling it, but the setting wouldn't "stick." Leaving the menu and coming back, the option would be off again. I unplugged the stereo entirely from the car, I hit the reset button a couple more times - got nowhere. I think I made a mistake when I eventually used the Android "reset to defaults" option. The display scrambled itself again. Here's the weird thing: While resetting, the car's antenna moved - I didn't see it, but I heard the motor run in each direction, up and down, in quick succession. Guess it may have moved an inch. After a few resets & key cycles the display came back up, but I was missing a few things - the "live" wallpaper and Torque, for example. I found the apks in the file system and reinstalled without incident. However, *still* no antenna, the antenna developer option still doesn't stick, and the display periodically scrambles itself. Much fun. Do like.
I contacted Joying, who politely offered to send a new display cable but informed me it was National Day in China and would be off for a week. So, maybe National Week? They asked if that was okay, and I let them know it is - I'm not pressed for time, it's no problem.
In the interim, thought I'd ask the brain trust here for opinions. It seems totally logical antenna control is just a software setting, so perhaps there's a fix. The display is more troubling, but perhaps a new cable will indeed fix it. Anybody have any opinions? Is it feasible to download a full Android 6 ROM (?) package and install it, see if a full rewrite fixes things? Something else?
Thought I should be polite and post the answer...
My display issue was a small internal cable connecting the mainboard to the display daughterboard. It was physically damaged, probably upon assembly.
The antenna issue was a VR on the mainboard was not outputting any voltage. Joying pointed it out to me and I verified with a multimeter. Probably a defective part.
I returned the defective head unit (was $$$ - price of buying from China, I suppose) and they promptly sent a replacement. The replacement did everything correctly, has been installed for a week now.
There are definitely some built-in quirks with these things which probably don't need to be reiterated here. Hopefully with some software tweaks I can manage most of them. This is all expected - the hardware works, and in my head that's all I was paying for anyway.
Now, to go find a better music player, launcher, and hopefully a simple way to actually shut the head unit down rather than sleeping it... this car tends to sit for a week or two at a time and the small (~.010a) draw puts the battery at risk over such long intervals.
Just out of curiosity, how much was shipping to return it back to them?
Did they offer to cover any of that?
Guys! Is there a way to control the antenna only when the "Radio" is switched on ? in my case the power antenna is extracted and retracted when I start or switch off the car. Not when using the "Radio". In my previous Kenwood unit (Non Android) power antenna was operated only when the Radio was used. Yes I know the Android radio is a software compared to the Kenwood unit. But there should be a way to operate the antenna on demand doesn't it ?

No, that is not possible. In these kind of android units the radio is always (!) switched on. The radio app determines whether you hear it or not.

I know this is an older post, but I am troubleshooting this same issue now. I believe this is (or at least should be) possible. Here are my findings from 3x different Joying models that I have tested.
UL135N2: Android 5.1? (This is the best/desired functionality)
* Power antenna extends when power on to the HU only if the radio app/tuner is active. (Turn vehicle on)
* Power antenna will extend when power on from pushing the volume knob (vehicle running with radio app active). Antenna also extends when opening radio app. Antenna stays extended when using home button instead of back button to switch to another non-audio player app. Radio app keeps running and antenna stays extended when switching to nav app.
* Power antenna will retract when power off from pushing the volume knob (vehicle running with radio app active). Antenna also retracts when closing radio app via back button or switching to another audio app (ie..BT radio, aux, etc.) after using home button while radio app is running.
* Power antenna retracts almost immediately when power off to the HU (Turn vehicle off)
UO135P4V: Android 8.0 (This is OK because the volume knob power at least controls the antenna)
* Power antenna extends when power is applied to the HU whether radio app is active or inactive (Turn vehicle on)
* Power antenna will extend when power on from pushing the volume knob (with radio app active or inactive)
* Power antenna will retract when power off from pushing the volume knob (with radio app active or inactive)
* Power antenna retracts almost immediately when power off to the HU (Turn vehicle off)
UO135N4G: Android 8.1 (This is worst functionality of all units so far)
* Power antenna extends when power is applied to the HU
* Power antenna will NOT retract when power off from pushing the volume knob (vehicle running with radio app active or inactive)
* Power antenna retracts after several minutes when power off to the HU (Turn vehicle off)

I am currently using a Toyota harness supplied by Joying. I plan to swap the amp.cont & ant.cont wires per some other posts to see if that might work. I found that the Metra 70-1761 harness seems to jump the amp & ant wires in the harness.
On another note, there are a couple settings (Antenna always on & Amp ON/Off) in the HU that seem to have no affect on functionality. I have reported this to Joying, but they "do not support this feature".
Hi all,
I believe that I am seeing the same issue in my Joying JY-UO138P4 radio as the antenna control lead never goes to 12v. Being that my car does not have a retractable antenna and only requires the power lead for the aftermarket adapter (amplifier); would there be any adverse effects to connecting the antenna control wire to the head units amp control wire and have it on whenever the head unit is on?
thanks,
dave

I don't believe that you'd need 12v on the ANT-CONT wire if you don't have a power antenna. Just connect the AMP-CONT to your amplifier and you should be good to go.

Sorry to bring this back
i dug into my car setting developer mode, where do you find the "antenna always on" option from?
I am afraid I have no recollection, but I might be able to poke around this weekend & let you know.
(As a side note, in case I didn't post it at the time - the problem with the antenna turned out to be the mainboard... I traced the circuit and found no output from the stereo under any conditions. It was eventually replaced.)
Last night I installed an Autosion Px3 Android head unit. The install was relatively easy considering a total lack of directions. After all is said and done I notice that my interior lights won't come on when the doors are opened. I checked my actual dash switch and it's in the correct position to allow the lights to turn on. My radio acknowledges when the doors are opened as well (little car with door opened shows up on screen) so I'm guessing it's some kind of function integration failure? I parsed the settings and couldn't find anything except swap functions in the CANBUS settings. Does anyone have any experience or other insight on a solution for this? Thanks! Vehicle is a 2013 GMC Sierra 2500HD.
I did it again....
Since last weekend I have the new Pumpkin here and test it extensively at my test place before I install it in the car.

Data
Scope of delivery:
2 DIN Unit
10.1 inch glossy screen, with metal frame
Cable set with 2 USB ports
User manual English/German
PX5
64-bit 8-Core Cortex-A53 1.5GHz
Android 9, build number 201907251651
MCU: CSN2_06252ß19_163051 (Despite this MCU the device is obviously a KLYDE device)
Here again an information to the MCU:
It is a PX5, but with a newer mainboard. The CSN2 devices are not firmware-compatible to the known PX5 boards, so there are no custom-roms at the moment.
First impression:
I must say, the first impression is very good.
The first startup was done after about 20 seconds.
The original launcher is as usual from Punpkin, as well as the apps included.
What's new:
Additional USB on the front panel
2 micro SD trays on the front panel
Volume control knob (illuminated)
Knob for App switching (illuminated)
App called "Tachograph," a new app for the Pumpkin USB-Dashcam.
Caravan, an app that supports rear view camera and front camera and you can switch between both cams. (did not try it...)
Sync (I don't know what it's for yet)
CD player for external CD players
An app called "Joykey Study" for certain OEM-Key-Pads, I have to do some research myself...
VoiceControl App Looks like an app for Apple's friends. The app doesn't work for Android phones (at least for mine).
The Settings menu was cleaned up, also the menu for the "factory settings". Here you don't find the strange menu anymore, but it's neatly clean arranged. Unfortunately not in German, but I think you can live with that.
Display of the battery voltage in the status bar is now possible in the "Personal settings".
Also the settings of the phone can be displayed now. Here you can see the field strength and the battery status at the top of the status bar.
The radio runs very smoothly and I was able to install all the apps I needed without any problems. Root was possible with the well-known ADB method without any problems.
The screen is connected to the radio with a flat cable plug, just slide it on and click into place.
You can turn the screen with a little effort in all directions and the holder makes a very stable impression.
First Tests:
The working temperature is important for me. With active route guidance, DAB+ active in the background, Blitzer.de active, the temperature stays ~60°C... and that without any optimization.
Yesterday I installed the radio. The first thing I noticed was, that Pumpkin is finally keeping the usual EUR installation dimensions for this radio. My previous radios always needed a reworked installation frame. A new frame is therefore due because the existing frame was reworked to fit my other units....
Potential for improvement:
Developer menu is password protected. The PW is even not known at Pumpkin. It's marked as secret... But i´m on it.
I got the information from Pumpkin that the new Android 9 design from Pumpkin is still in work. I'm curious when that will come. So I'll show you some pictures as soon I will get it from them.
On my car the phone keys don't work right now, they are not recognized by the app. So I had to change my voice key so that I can answer a call via the steering wheel and hang up (double assignment of the actions goes via long click).
Recommendation:
For me its´s a clear YES, because I don´t need any custom rom. I just use another launcher.
Please comment on the 10-inchness implementation
Did you have to cut into your car plastics? Or does it stick out an leave a gap? Was there a snug adapter with no gaps and no cutting?
Does it tilt/rotate? If it does, does it stay in place when you are operating it or wiggle under your fingers? Does it stay still on bumpy roads? Etc.

The unit is exactly 2-DIN large so there is no gap and nothing has to be cut from cockpit plastic at all.
The screen stays completely in place even when placing the hand on the top and using the thumb for a screen touch on bumpy roads.
... and yes, it stays still on bumpy roads.
For my car (Mitsubishi ASX) I need a car specific adapter, because the OEM unit is 2-DIN high but about 6cm wider than 2-DIN but with just a 6" screen and lousy firmware/UI and OS. The adapter I buyed needed to get cut, because nearly all 2-DIN chinese units are not really 2-DIN, they are a bit larger. To get the chinese units in my car, I had to cut the hole larger.
With the new unit I would be able to use the original size... so I have to buy a new one.... unfortunately...
You can tilt and rotate the screen to get rid of any glare and you can move the screen up and down, to get the right position at your dashboard.
Until now I don´t see any bad behavior.
