Hi

Got rnse installed in to my a4 b7
Originally had concert double din

Cant connect to radio or navigation via vcds

Did have some other fault where it kept switching off and buttons were not illuminating but started working once pin c7 was moved to pin b5

Car has navigation
Shows up on cluster
Non bose
No cd changer
No phone
No bluetooth

Does have a parrrot kit installed

Would that affect it connecting

Or does it need coding properly?

Any help would be appreciated
