Ok - tried to wire it in today - found the plug cable tied to the frame tube behind the Aux socket, pulled off the dummy plug end to expose a two pin female oval plug - this is not the same as the Garmin GPS plug I had on my 1200 GSA which is a three pin ( BMW) part, white with three wires, one of which is redundant - i have DIN plug from my 1150 so I wired that to the lead, but the GPS will not take power from that source - the cradle and lead are ok, as tested on a non canbus bike.
Assume the Aux socket does not like Zumo's
Nippy Normans website states that the RNT does not have the canbus socket... So what is the one I've found...And anybody know what plug it takes??
