Here is my project taking shape after working on it for quite sometime. I kept the original radio but built a hinge over it to hold the display and fold up to access the radio buttons.

PI 3B+
7 Inch HDMI display
USB Hub
External Bluetooth Dongle
External USB Sound Card for audio output to car and Mic input
12V relay for display power control
12V Timer relay for delayed PI shutdown  (Basically what happen here is : when power to ACC is lost meaning when key is turned off, the 12V relay will trigger GPIO signal and PI will cut the HDMI signal to the display, this will make the display to go to sleep( built in function of the display), but the PI remain powered for about 30min... if power get restored before the 30 min the 12V relay will send the signal and PI will restore the HDMI signal and things are back to normal... but if ACC power is not restored, PI will shutdown after 30min and 2 min later the timer relay will cut all power to the PI).

Reverse camera is still a work in progress...

Want to say thank you to BWS for the software job and everyone on this forum for your input and inspiration..

Nice! I'm a VW guy myself! Looks good.

I assume your radio is functional? So you have an Aux input on it or something to play from the Pi? Is the screen easily removeable? Any concern for theft?

Looking slick though!

Thanks...... Yes the radio still works, i am using a CD changer port to AUX port convertor (Blitzsafe) to connect the PI audio. the screen can be removed fairly easily.., theft wise not too concerned as it doesn't standout too much when looked from outside

Hi Cantonebiat,

I would like to ask You, what screen did you use exactly? Do you have some link, where it can be bought?
