Good morning everybody.
First of all, i'm new and Norwegian, so you will probably notice some bad english from me..

I have an Audi A4 B8 8K Avant 2009.
I love te car, but there is a few downsides!

-Bluetooth not enabled

I want colored screen(s) and enabled bluetooth function.
Can this be done without any huge costs? if yes, how?

Any help is appreciated
