My bike is a 2011 R1200RT premium and came with no GPS. It seems that Garmin is the "go-to" GPS brand for motorcycles but I had an old TomTom system in my car and when they offered me a big discount this past Christmas, I decided to go with their new TomTom Rider 550 motorcycle GPS. Wouldn't you know, their standard mount that fits probably 90% of all other motorcycles wouldn't work for the RT's handlebars. The result was a two-fold challenge. Either buying an expensive aftermarket mount or fabricating my own.
Then, where to connect to a "switched" power source in order to have a protected power circuit that would also automatically shut off power to the unit and prevent battery drain if I accidentally forgot to manually shut the power off when parked.
Thanks to the search feature on this forum, the wiring schematic in my Haynes service manual, and my (marginal) innovative skills, I managed to accomplish the task.
I did not check to see the voltage at the unused accessory connector already built-in the wiring harness, but I am assuming it is a 12V DC circuit. I believe just about all automotive accessory devices on the market are constructed to accept a 12v power source. Those operating on less most likely have a built-in current limiter/regulator for operating on lower voltage.
Turned out that my greatest challenge was getting the correct companion connector for the wiring harness from my local BMW dealer. I'll not go into more detail (rant) except to say that the 120 miles round trip to the BMW dealer in Asheville, NC was a much better experience in customer service/attention/appreciation
than the 24 miles round trip to my local dealer!
Two challenges remain, however, becoming proficient in understanding the operation of the device, and Bluetooth pairing it to my helmet Scala radio. I also will probably need to get a sun shade for the screen but more important to use Bluetooth verbal communication in order to keep my visual attention/concentration to the road ahead.
I'm not familiar with your model bike but believe if you take the time to research the subject here, buy a service manual, and additional internet reading, you will arm yourself with enough knowledge for an acceptable solution.
