Re: Wiring a GPS on a 2009 RT
Yes the connector will have a cap in it and it is tied to one of the front support bars generally a little to the right and forward of the steering head area. This is a three wire connector. #1 is ground, #2 is signal from bike computer with information for the NAV computers (digital) #3 is 12 volts +. You can buy for 15 or 20$ a BMW plug that goes into this connector and gives you three wires about a foot long each to work with and now you have a clean way to hook up your power supply. This goes on with the key and goes off 60 seconds after you turn the key off. The PN is 8330 041 3585. You may need to hook up a converter that may come with your gps for 12 volt power supply. Most GPS units work on 5 volts.
