I have a 2010 E90 320i in Japan (CIC). It only has the basics: no Bluetooth, no reverse camera, parking sensors, etc.
I'm working my way to install everything.

I found someone selling a tv module (see photo below), he says it was pulled out of a 2008 m3 e90. The part number is: 9 146 702.
Some questions:

1. Is this compatible? When googling the part number it shows this is for the E60.
2. The part number seems to be for Japan only, so I'm struggling to find information about it. Is there any equivalent p/n that I can use when searching in Google?
3. Where can I buy the cable harness or the parts to make the cable harness? What are the connectors names? Where can I find a connection diagram?
4. They sell it without mounting brackets or anything. Will I be able to install it without it? I guess could make my own out of wood.
5. If I install this module, will I still be able to set up the reverse camera?

Thanks!
