I picked up BMW's Nav III (Garmin) for a song, don't ask- I ain't singin' it again...
And the plug I believe is set up for the R1200GS. (or is it?)

Does anyone know the wiring color code? White, black, red.
I located a plug that the Power plug goes to on my R1200 "C" but it looks as though the business end is the same as the one coming from the GPS, Male.
I may just be easier to just cut the plug and fuse/hardwire, alas I don't know what the white wire is for? Audio?
Thanks in advance...
