Have you played around a bit with the arguments for the commands:

SET PROFILE AVRCP TARGET 7
SET BT CLASS 280428

I suspect you need to enable a bit in the second one. Maybe just try setting all the bits? The car audio system will/should probably only look for ones it cares about.

You've selected "Car Audio" but that's not what *your* device is so sounds a bit strange but I'm not an expert.
