This unit seems to have all that I would need and is only $199. Anyone here use one on an RT? I have a 2009 R1200RT and it already has the accessory plug for a GPS already taped near the steering column under the dash. I also have purchased this plug's mating end and I think I can just cut the power supply cable that should come with the gps so that power from the bike could be obtained. What do you think?
