    There are 3 connectors in the fork area of the 2010 - 2012 R1200RTs. The BMW cables for connection to the connectors are: 1. #83300413585 - This connector is used to power the Garmin Zumo 660. It can be wired directly to the Zumo power wires (red = power, black = ground) or it can be wired to a relay that controls an auxilliary fuse panel. If direct, Zumo power is controlled by ignition key, if to relay, Zumo can remain on when ignition key is turned off. 2. #83300402344 - This connector provides audio in to the BMW audio system from the Garmin Zumo. Using it will allow the direction voice prompts from the Zumo to be heard through the BMW audio system. Radio output is muted to give Zumo audio priority. This connector requires attachment of resisters or a stereo to mono adaptor (from Monoprice) to get to the required 3.5 mm plug to supply mono input to the BMW audio system. 3. #83300413584 - This is for the R1200RT audio out. It can be used for additional amplifier and speakers or for external audio in-helmet systems.
