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.

I am thinking of buying new HU becouse my existing Hu from Hizpo PX3 7.1.2 is kinda wired, mostly because none of beetter DVR cams do not work.
So I am thinking of this one
https://www.aliexpress.com/item/32934575168.html?spm=a2g0o.cart.0.0.78b03c00oKlwsb
anyone have experience with Eunavi HU?
It's similar to the one I have, it has a few problems with my Skoda Octavia.
It boots up every time it powers up taking about 20seconds.
The canbus doesn't work with all the steering wheel buttons.
The default apps are rubbish
The theme is shocking and you can't read the text properly.
Short of the power on issue, it's not too bad.
i see.. original rom I had on hizpo px3 had similar issues, like power up it was even longer.. but with hal9k rom or "malsik" that changed.
I'm still waiting on eunavi sending me the firmware so I can have a look at fixing the problems.
It's not a problem with it booting up each time, trust me.
I have a dash which goes into standby mode and it drains the battery in about 3-5 days of not using the car for a decent drive. I'm forever having to use jumper cables on the battery. I've since installed a switch, although you can use a relay - to make it boot up every time.
I've just bought this unit btw. I'll let you know how it goes in a month. Hopefully it can be modded.
Hi, how is the unit? Have you had any chance to use rca pre outs? I want to buy an android unit but the only thing stopping me is that Subwoofer preout are either of low voltage or doesn't work at all.
The seller claims its a 5v rca pre out for the sub.. Can you confirm this?

same issue here
So I have the same unit and the same power-problem, takes long to startup every time.
Tried swapping +BATT and ACC but that didn't help the drainage.
Also, mine doesn't hold the radio presets and USB2 doesn't work.
Left a message with Ali-E. to help me with this problem.
My car is a 2011 Dacia Sandero Stepway, which is Renault, basically.
**** solved ******
wire was crossed in the pigtail - radio preset hold, eq.settings hold and lots of other stuff fixed by installing Malays full ROM for PX6/STM32
have autI have autoradio android vw Eunavi I need the secret numbers to open the settings and the habit of adjusting the factory.
Hello. I have an Isudar H53 with an Intel SC9853i processor. The manufacturer writes directly and I am in contact with him that the unit can not sleep! I saw Joying units with Intel. So they sleep. I find that my unit probably also allows sleep mode, but there is a mistake that after about 30s the unit turns off completely. but for 30s after turning the key turns on almost immediately
I will send the video to you in a private message upon request. I can't post links here.
I beg you for some ideas how to solve this mistake to keep the unit sleeping. Thank you
Is it compatible with joying firmware?

I do not know. how can you find out? can the canbus unit also influence this?

Normally the can bus should not have that influence..
If you know how to use the terminal on android then please do a "getprop | grep -i fyt".
If your unit is a FYT unit, like the Joyings, the above command will show some FYT identifiers.
If it is not a FYT unit, it might be a STT (QD) or MTCD/E unit. If it is an MTCD/E unit it should/might have "deep sleep / quick start" options as well. If it is an STT (QD) unit, probably not.
You also sent me a PM with a picture: https://ibb.co/WcjTy06
It doesn't mean anything to me and does not look like a FYT unit (that's why I asked you to make a post in the forum instead of a PM), but maybe someone else knows.
thanks to try the terminal. otherwise my knowledge is still such. I measured different power at the unit. the canbus goes to 12V constant voltage. when the ignition key is removed, the voltage from the canbus is immediately switched off to the main unit. I do not get into my head as it is possible for about 31s the unit is off, but by then normally normally turns on about 1-2 seconds. how can this condition work when no power is applied to the unit?

Hello
I have also ISUDAR H53 unit. I measured the current consumption, it is ~0,5-0,8A after power off, 3-4min later it fall down almost 0A. I think it is perfect sleep mode. The starting keeps ~3s after power on. If you totally disconnect the power socket the starting keeps much more longer (starting android...).
