I have tried getting android working with my 4.4.4 version. Unfortunately the kernel they ship the unit with has castrated drivers. It is most likely the same for Android 7.1 unit as well, though android 7 should support USB audio in theory. You can try usb audio player it comes with custom driver, though you won't be able to route audio from other apps and will limit you to stream local music only.

I ended up modifying my unit by replacing capacitors and resistors. The bass is back. The stock choice of components is absurd. Did those guys ever read data sheet? It is possible they were hiding some problems but I didn't discover any side effects. The high frequency response is more challenging as input impedance on BMW drops significantly as you go high in frequency. I was thinking about installing headphone amp inline, or purchase a small active mixer. As an alternative I was also using 2 apps to route unit to the phone: Allstream and AiSound. All stream provides higher output (louder), neither app provides bit perfect audio though. I was receiving audio on the phone and sending it to my aftermarket BT adapter. The issue with this solution you would need to automate the whole process (which I did with tanker) but the drawback is horrible lip sync. If all you car is audio you can try chrome cast audio or apple airplay or old android phone (something I plan on trying) to route audio to.

Hi guys,

I found this thread after I search in Google for some updates.

I have a BMW e90 with CCC and bought one from AliExpress with Android 4.4 and 1 gb.

Everything worked good, but after some time the left speaker don't play sound. In the original idrive it works, and when I play sound through aux(example Waze oder Others navigations) the left speaker work, but music and videos and YouTube just plays on the right side. I tried the balance fader only the right is working.

Does anyone know how to fix this. Will an update help?
[Android Head-Units] kalinkamaen:
Is your AUX cable connected?
[Android Head-Units] Sanjka:
Yes it's connected, when I switch the red and white one, it's the same problem.

Without aux I can't hear sound from the Android, just navigation apps will give sound through can bus to the left speakers.
[Android Head-Units] Sanjka:
What I did forget so say, the problem appeared after I changed the volume over 34.

kingroot installation, No Signal...

Hi all,

Having read multiple posts in this thread also tried rooting my 1st gen with kingroot.....however this resulted in NO SIGNAL....

used kingroot 4.5, it rooted successfully.

installed supersume....it installed, but no response when opening it.

few seconds later....NO SIGNAL.

Anyone else with similar issues and know a fix?

Highly appreciate guys....

As this thread is a lot more active than the E series head unit thread, I thought I would as these questions here as the units are the same firmware (I believe)

I have a E90 Idrive android 7.1.1 32gb 2gb ram headunit and installed it last week. Overall I am pleased with the results and the newer fresher look to the car infotainment system.

I do have a couple of things I cannot seem to sort out.

Coming from a 6.5" business Idrive screen, I get a splitscreen dash in OEM mode - the right side showing fuel in tank, seatbelt and speed - the issue is that the seatbelt is set to the left (passenger seat) and I have tried to alter the factory settings and change the door to right which in previous android units has solved the issue but not this time.

The other issue is the screen shows the speed in MPH but the actual speed is KPH and I cannot see any way of altering this, either in the standard or factory settings (the settings passcode is 1314)

Only two small niggles but they are starting to wind me up. lol

Does anyone who how these issues can be resolved?

info from unit.

I have a 10.25 inch Gen 1 4.4.4 unit for my F30 (originally with 6.5 inch CIC) that I bought from one of the vendors at AliExpress. I have not updated the MCU since I installed the unit in Nov 2017. The MCU version is Aug 2017.

I realise that after I installed the new firmware, ID6 does not come up as an option probably because the MCU has not been updated. Does anyone have a newer MCU file that is suitable for this system?

Apps losing stored credentials?

Hi everyone, I've got an annoying problem on the Gen 2 running Android 4.4.4 in my F21.

I've tried a few additional apps to the default and generally there's been no issues with anything (other than the delay setting GPS & Time).

The annoying problem is that with applications that have logins (Waze, Sygic, Spotify, etc.) at random, but frequent times, after the vehicle has started and I open one of the apps, it runs as though as though it's the first time and asks for login information or shows the original startup screen for the application. Waze asks you to login with your details, Spotify asks for your email address / password, Sygic defaults ALL the settings back to defaults (MPH back to KPH for instance).

Does the Avin store this information somewhere volatile requiring it to be re-entered frequently?

It's not that it doesn't work, it's just the frustration of having to re-enter and reset everything.

update

Hi All

i have recently installed a avinusa gen2 7.1 unit in my F22. i have been noticing some issues with unit mainly in being slow and google maps not working very well.

i have been reading this thread and people have been mentioning updates released from avin, i have contacted avin and didn't get a response so i was hoping someone on here could point me in the right direction and also and advice on making the unit better.

Thanks in advance

[Android Head-Units] jeffc83:
I think I may have found the manufacturer of these units;)

I want to check the config XML Files. The files are all called "customer_***.xml". in other units and there are about a dozen of them. I think they control the GUI for the different resellers. The two "Customers" with the bigger XML-FIles are OCCAR (奥车凯) and Carcool (车酷时代). I don't know if they are manufactures or resellers, but a circuit board on a VERY similar unit is also labeled with OCCAR, so I think they are manufacturers. Might be Occar?

I unpacked the .img file last night using RockChip Factory Tool v.5 in order to dig into the ROM. Nothing evident on who the manuacter is from my quick look that i did. Looks like there is a generic user manual in Chinese and english in the root of it though, with no indication on manufacturer.
[Android Head-Units] jmoney99:
You guys have been busy. I haven't seen the reboots / slowdowns that you've had, probably because mines the X3 and the back of the screen / part of the top is covered by the dash. Antutu bench shows the CPU is mid-range (total score 19294, CPU @ 9750, ram @ 2601). The CPU score is similar to a Galaxy S4 but the ram is about half the speed. CPU on AVINs site was stated at 1.6Ghz, but CPUz shows it as 1.2 Ghz (Chinese marketing again?). Looks like they put this chip in quite a few headunits (RK3066): https://xdaforums.com/android-auto/android-head-units/rkpx3-identify-unit-options-t3585126

Think this chip has a problem with the google app (maybe app isn't optimized properly for the hardware). Right now I've forced GPU rendering in Developer options, and using 3C Toolbox to set the following: vm.swappiness =10%, cache size=4096, io scheduler=deadline (system manager), CPU governor =performance (cpu manager). 3C also has a decent task manager / startup manager to minimize apps. Using seeder 2.0 (from XDA) as well @ light setting to optimize entropy. Performance seems to be pretty good at these settings and I don't notice much lag once everything is properly loaded. I did try switching to ART a while ago, but settings didn't stick (probably got lucky since it looks like that could've crashed it).

I'm using a hack/work around right now for the 24-hour time. There is an app from the playstore called "init.d scripts support" that will allow you to run system scripts at startup. Scripts can be located in any folder (I just put it in a separate folder on the internal SD / data dir. It does require root and you could probably put the script in /etc/init.d and not use the app but I didn't want to mess with the system directory. Set to run scripts at boot / no execution delay. Use notepad++ to create a simple shell script and save it as a Unix script file.

Script name: set_time_12_hr.sh

Code:

#!/system/bin/sh
settings put system time_12_24 12

Script now executes at startup and sets the time to 12 hour. Might be a slight delay as it changes from 24 hour to 12...but works for now.

You have the benefit of not having direct sunlight heat up the little guy. I've tried various performance tweaks on it, but resorted to leaving it stock because it is very sensitive to heat. Won't have that problem long since cooler weather is coming, but its a temporary bandaid.

[Android Head-Units] wiltrup:
My factory screen, before installing tha android unit in my f10 was a 6.5"..

I have now managed to code the car via ESYS to a bigger screen and with split screen.

When in my factory screen, I can see the factory bmw system, trying to take up more space, when activating split screen, expanding the screen to the right..

But there is no setting in the android unit, that removes that right infoscreen... so the factory screen can only show me the 6"5 space...

Does that make sense ? My English isn't perfect..

Is there any way to adjust the android to thinking, that the factory screen was an 8" or bigger ? So I get the factory screen to take up more space?

Almost correct. This touchpad does fit cic controllers for F series ONLY. It does not fit cic controllers for E series. So I had to improvise.

SO i found out something kind of interesting. I was messing with my setup which is currently a Tune2air and the CarPlay adapter which kind of sucks cause you have to change the audio source back and forth every time you get into the car plus siri and navigation don't output any sound. Well i left the tune2air plugged into the usb and plugged the aux from that into a splitter along with the aux cable from the head unit. To my surprise the audio is near perfect quality from the head unit. When i remove the tune2air from the usb and aux and run just the aux from the head unit it sounds like garbage. The only remaining issue is the output is kind of quiet. It doesn't make sense why its working with perfect audio and everything working but I'm not going to complain. Just thought i would share.

Does anyone have an archive of older firmware versions? I installed newer firmware on my Gen2 7.1 system and I really think that the older version worked better for my purposes. Newest versions don't work well with GPS, and slightly older versions seem to be somewhat slower. I'd like to do some comparisons. The older version I have access to is from June of 2018 from an archive posted to the bimmerpost thread. I'm looking for anything that might run on my system and be older than that.

This sounds like what was happening to my unit when I first installed it in my F30. I had a USB-powered Bluetooth receiver in my arm-rest. Powered off of the USB in the arm-rest with its audio out going into the AUX port in the arm-rest. At the time, the audio from my AVIN unit was total garbage, ie. very quiet, static-y, and under-water sounding. I figured I need to wire the AVIN Aux out to my arm-rest port, but immediately when I unplugged the Bluetooth receiver from the Aux input, the sound from the AVIN became streets ahead. And if you don't know what that means, you're just streets behind. ;)

Car type issue

I have just installed the Avin Gen2 7.1 unit to my 2013 F30 with entry nav and 6.5 nbt screen.

I believe it is a champ2 system.

The issue I have is that I have tried all the car types available in the factory settings but cannot get my iDrive screen to fit properly.

Either I lose about 1cm from the right if I choose the 6.5 half screen or it stretches it way out of proportion if I choose fullscreen.

Other options just show a screen with interference. The only one that is partially usable is for 7 series 8.8 10.25 option, however I then lose about 5mm from the bottom of the screen so when I go into iDrive the last option in any screen is no visible.

I have the latest update.

Is there anything that can be done regarding this?

If not I will take it out and go back the factory unit.
