I recently bought Pumpkin head unit to my Audi A3. HU itself is quite nice, fits like original, and software is surprisingly good and stable (I had some doubts but decided to buy it anyway). Problem is that there is no ACC wired in car's connectors, instead original unit is powered off via CAN. Now, when I turn off the engine, HU powers off too, while it should stay on, and power off when I pull the key from ignition switch. This means, I can't listen music without having all ignition powers turned on. I earlier had an Alpine HU, and it worked perfectly, eg. powered off when I pulled key from ignition switch.
Is there any way to tweak this behaviour in android side? Or is this CAN decoder's job? Other than powering off, CAN controls seems to work ok (multifunction wheel, dimming, etc).
Details from my unit are: RK3188, KLD6, 800x480. CAN-bus decoder doesn't have much info, just KLD(AUDI-SS-01), SS-AD011030158-0.

Mine came with a harness that tied into my canbus, I'm sure your unit has the capability you probably just need the decoder that is specific to your vehicle. On a side note I to have a RK3188 800x480 and am looking for someone to pull the stock recovery. If you're willing let me know it won't harm your unit.

Don't know about the decoder, it should be ok, at least there's "For: AUDI A3/A4" in it. Tried to google it, I can find lot's of same looking decoders, but not much helpful info about it.
I can pull the stock firmware, just need to learn how to do it. I've been doing electronics and linux stuff for ages, but Android world is still bit new to me.

Ok, I will give it a try tomorrow.
Interested in the unit you bought.
I'm interested in your unit. Where did you buy it, could you please send me the unit's link?

Since I still have so low post count, I can't post links. Google "11-C1217-UK-A" and you will find correct HU from Pumpkin's website.
I sent question to Pumpkin too, and an answer from them: "it's normal when you turn the ignition key to off position the unit will switch off, cause the unit switching off is controlled by your car canbus system, and it sync with your car instrument panel".
Still, I don't consider this as a normal, since Audi OE head unit, and also earlier Alpine head unit didn't power off until I actually took the key off from the ignition switch. All Audi's I have and have had behaves like this, from the oldest Audi 80 (1994) to the newest.
So, is there any ways to analyze CAN data, and tweak the unit so that it would power off when key is taken away from ignition switch?
Dave, sorry I still don't have the recovery image, so busy days, and I'm missing USB cable to connect to the unit. But ADB is installed etc, so it will come eventually

No rush whenever you have time my unit is working just no recovery.
I think I remember reading in the HU Q&A thread a way to change canbus options I'll try to find it.

Hi sohlo....
I haven't answer for your prob, but i just want to say that my Greenyi HU run exactly like you suggest.......if i turn off, the HU still ON, and switch off only if i keep the keys out from the ignition.
So, it's possible.....but don't know how...sorry.....

Hi there, ive recently installed the same on my A3 (well an android head) can you tell me the age of yours and what loom connector you bought? some of them mix the live and ignition live up and they just need swopping over.
PS are your rear speakers working? took me ages to fix mine

My A3 is 2005. I have ISO connectors (non-BOSE), since originally my A3 is single din and I converted it to double din. I have checked wires again and again, they seem to be fine. Permanent live goes where it should, and ACC hasn't been wired at all in car side, because of CAN power off. You have same Pumpkin HU?
My rears are working OK, I just have to set fader quite heavily to back, like 70-80%. I had the same problem with earlier Alpine unit, had to set fader way back.

It seems that your unit is KGL/HuiFei (mine's KLD/Klyde), so there's propably some differences. Also CAN adapter might be different. Can you confirm this?
I was finally able to extract the stock recovery from the Update.img https://www.dropbox.com/s/9b3azwgmqm...overy.img?dl=0
This is from RK3188 800x480 KitKat 4.4.2 KLD6 2.81

Good to hear. I still haven't been able to get adb detect my unit, actually when I connect usb, even lsusb doesn't show anything. I have tried to turn on adb in the unit (adbon), but still no luck. Well, will continue to try

I think the only way is to use adb over WiFi.
If you need to root your HU this is the method I used
Flashing a pre-rooted rom doesn't seem to be the only way any more. If you go to Settings->Factory Settings, and enter**#hct#root#* as the password, it enables root on the device.
This appears to be a permanent root which persists after reboots.

So it seems, at least usb was all dead for adb. Need to study more, first time ever trying to debug Android.
Actually, seller agreed to accept return and refund the unit, so I might switch to HuiFei/KGL unit if I just get a confirmation that it works better. Now I just would like to know if this CAN issue is because of the CAN bus decoder, or because of unit configuration. It was mentioned earlier that GreenYi unit works, and it seems to be KGL, but then again, I don't know is it decoder or unit which makes the decision of power off.

One thing to check, go to factory settings enter 126 as password and verify your canbus is setup for Audi.

Strange thing is that canbus is set to none. And if I set it to Audi (or anything else), steering wheel controls etc doesn't work at all.

That is strange, with it set to Audi does it stay on until you pull the key out? There's also a steering wheel mapping utility in factory setting I believe have you tried changing that with Audi selected? Make sure you take a screen shot of your original settings.

Hello, i am new on this forum and i can see that there are a lot of expert with really precised answers.
I am french and i bought one head unit on aliexpress.
I am on android 8.1 SP9853i and MCU version in attached.
I am facing some sound issue... everythings works great (option camera etc ) but i have some intermittent sound cut like if the system try to load something. This issue is for the global sound (bluetooth, radio, internet ) it' cut for around 2 or 3 seconds everytime and sometime the lighting button on left swith off quickly.
i tried with canbus disconnected and all other wires but still occurs.
If somebody can help me..

Like all chinese sh...t, you need to open the HU and check all the flat cable.
Unplug and plug very gentle on motherboard and videooard (behind display).
Thanks a lot for your reply !
I already did that for flat cables byt it's not better. I will do that again to be sure.
It's really like the system search something. I changed the car model in MCU, i tried to unplug all option cable behide but nothing better. Do you think that could be a problem of MCU version?
And another thanks to take time to help me !!

Maybe you have problems on tension plugs(12 volts).
Try to understand if the issue come only on bad streets when the car is shaking.
Hey guys!
I'm hoping you can help me out with some issues I've got with my Android head-unit.
The model is a NAVD-MT049 for an Audi A3.
It's got the reverse cam installed, and for a while now I've been having issues with the video feed.
I've noticed that sometimes when I switch in reverse the camera first displays No Signal, and then after a minute or so it starts working. This happens almost everytime now.
Any tips on what could be the issue?
The wiring is done as it should be, and I've been using it for 3 months now.
Do I need yo get an MCU update?
I've read that on some models this can solve the issue, but I haven't found a website where I have the compatible version for this unit.
Any feedback is welcome!

No, you're right it's not an MTCB, it's a chinese head unit and the MCU is TS907.
Maybe the moderators cand move this post to the correct thread?
