[Android Head-Units] InHuM@N:
Hello all,

I've recently boght a android multimedia system for bmw 1/2/3/4 series from 2011/2016.

Product can be checked here: https://avinusa.com/bmw-1-series-2-series-f20-f30-2012-2016-android-multimedia-navigation-system.html

Brief overview of the mount process and software (custom launcher) here: https://www.youtube.com/watch?v=eDk65xXrjxk

Main features are:

(RK3066)

Android 4.4.2

1.6 Ghz Dual Core CPU

1 GB RAM Memory

8 GB Internal Storage

8.8" Wide HD capacitive multi touchscreen

Screen Resolution 1280x480

Ambient light sensor to auto dim LCD at night.

It all seemed pretty cool at distance but taking a closer ride this is a very bad system, I will detail the main bugs & fails that i've detected so far:

True android settings are somehow hidden and blocked, event traying to force them to popup the system returns... example :

Set Date/Time and Time Zone impossible to go to settings.

Bluetooth exists but impossible to acess settings menu, it's hidden and when I use a App to force turning on bluetooth in freezes that apk.

The car Menu button should be binded to the default launcher, instead it allways launches the custom one. Impossible to disable that App.

Trying to access developer menu the system says I'm already one but I can't even go to the standard android menu... just a custom menu with a very few settings

System buggy behavior:

I have full parking sensors front and rear... the system only shows the sensors car grafic when rear gear is set... when I put a "front" gear the grafic closes but I still have the PDC ON with the PDC button... system should be binded to the PCD Button and not to the rear gear.

Imagine you're watching a movie,tv or any other open App... when PDC leaves the screen the system sends you back to menu custom launcher and stops what you were doing previously... completly absurt behaviour.

It's said the it preserves the steering wheel commands... well just the volume, skip track, telefone and voice command are unbinded to the android system.

Original car system comments:

(this is not my car, it's a 3 series 4 doors... system is the same) The right side menu with a car and 000 are the digital speed and on the car shows the open doors... issue? my car is a coupe 2 doors only so the system is expecting 4 doors... so my car has allways the to back doors open on that feature... like wings wtf :confused:

Another thing is the size that this added box fills in the screen... the idea was to not stretch the original menu that is 800x480 and the new screen works with 1280x480... but the measures and incorrect and the original system gets stretched anyway... I found that other systems like this with probably another rom have a diferent right side custom with another aproach like this one:

Has some board computer info besides the doors and it seems much more pretty display then mine :(

I will continue testing this device and update this topic with more detailed bugs and details.

I'm also trying to understand how the edit of this kind of rom works... I'm a web dev but no knowledge on android systems...

I have the update.img that it was given to me by the seller... I was able to unpack with imgRePackerRK but... thats as far as i've been... I now have an update.img.dump folder:

Extract LOG

Can some one please help me understand if this bugs / problems from 3 above lists can be changed/fixed with some development ?

- Erasing the android menus restrictions

- Enabling bluetooth managing (bluetooth works to pair phone and airplay but it's completly closed to manage the bluetooth)

- avoid the car key menu to be binded to the custom launcher, instead bind it to the home button of the system.

- avoid that the car PDC graphic to be binded to the rear gear, instead be binded to th PDC button of the car.

- avoid that system closes the current app by entering the PDC view and on "callback" it returs to the fu***ng custom menu.

- refactor the side info menu on the original bmw OS side to fill the resolution gap to something more pretty and cool like the picture shown.

Thank you all in advance,

V,
