I’m mid way through installing the Pioneer 77 DAB Head unit (on my NC2 with Bose) and a little stumped.
With limited instructions I’ve connected the connectors the fit together, routed GPS, microphone and rear view camera cables behind the unit but I feel like I am missing something.
I have 2 connectors which were plugged into the old Bose unit which I don’t fit into anything from the new unit.
Pink is for the speed pulse that drives the speedo so the head unit knows speed.
With a bose stereo - there is no speed pulse behind the stereo - you would need to pick up from behind the clocks ( white wire )
Blue/white is for a signal coming from the reverse light +ve to tell the head unit to switch over to your reverse camera.
Green is for connecting to the handbrake ( it is only needed for video watching functions so you can’t watch a video unless the handbrake is on )
