Ok can someone confirm which reference lead I need , I want to fit bluetooth into my car and it seems with the Bose fully amplified system without paying a fortune for oem parts an aftermarket double din with built in Bluetooth seems the way forward.

my car has the sat nav audi flip screen with the quad lock rear connectors, one large block on the top which I think is power etc, and two smaller white blocks below, hope this helps.

thanks in advance.
