Ok so my first post an introduction and a question. I have been riding since 1970 mostly off road racing and a couple of years street riding experience. I am buying a 2013 90th Anniversary Edition Low Suspension bike with 800 miles on it. It does not have a nav unit on the bike. I have searched the forum and cannot find the answer I am looking for. Can I add a BMW Navigator 4 or 5 and have it integrated in to the controller on the left handlebar? I thought with this controller the nav unit could be controlled through it but maybe I am wrong. My guess is an off the shelf new Zumo 590lm wont integrate to the BMW system and would be touchscreen controlled. I am really new to the m/c world of navigation but well versed in the car systems. Can someone help a brother out as to my best option for my new to me bike. Oh yea, I have a Yamaha GTS1000 in the garage.
