I want to sync my Android Bluetooth to my 2008 A6 that I just bought used. The guy I bought it from was not one to use all the technology, but it looks like it has a lot of bells and whistles, but I don't think it has Bluetooth. To confirm, I switched the ignition on, and turned on my android and scanned. Nothing was found. I assume that means I don't have Bluetooth? What options do I have?
