OK so I want to hook up either a Bluetooth receiver or a 3.5mm jack to my stock concert 2 radio. All the videos say I should have an mmi thing in my glovebox but theres nothing in there. Is there anyway I can do this or do I have to get an after market radio? Or is there and stock single din audi radio that has the front aux hook up that I can put in my a3?
