I have a friend who's wife is trying to help him be able to use the MP3 player on his BMW motorrad GPS with earbuds. She asked me for help since I use my 660 with earbuds. I use the aux output jack from the octopus wiring harness or the actual jack on the side of the unit. Problem with helping her is the cradle for the BMW GPS covers the jacks on the side of the unit and i have no idea what the original harness looks like since it was dealer installed. Anyone know if the wiring harness for the BMW unit has the output jack or is their another way to use earbuds with this unit without a lot of re-wiring?
