I've been digging around online and found some scare details on anyone who has successfully added oem bluetooth to a vehicle that doesn't have it.

I have a 2007 A4 without NAV. Is this possible?

I was told it was not able to be done on my bmw and I did it rather easily. I'm hoping the "it's not possible" answers from various audi pro's is wrong.

Anyone researched this or done this already?
