I bought a Aux vw kit for my audi a3 radio... however it only works if you have the plug for the cd changer...
My radio has the built in cd changer, bluetooth , steering wheel controls and Tape deck (yuck)
When i took the radio out i found this mystery blue wire... could i somehow tap into that?
if not what options do i have to retain blue tooth..ect
i dont want to use a tape adaptor
