I posted a few days ago that I tried to install the Blaupunkt London MP37 and was getting the "PHONE" error that everyone else got. According to the directions, you are supposed to cut the telephone mute wire on SOCKET A, PIN 2 of the stock wiring harness. On my harness in this location there are two yellow wires with a gray stripe going into this one pin.
When I cut both of these wires, the radio works but I no longer have working reverse lights (which is why my backup camera stopped working). It's definitely not an aftermarket wiring harness but I wonder if they changed the wiring harness colors (or am I cutting the wrong wire(s)? I have the stock headunit with NAV.
After re-connecting the wires I cut, my reverse lamps work again as does my back-up camera.
I really need some assistance before I decide to return the radio and deal with not have a source for my MP3 player.
