I can not find a good place to install the GPS (do not care for the looks or the exposed wire of the handlebar mount)and really only need it on fairly rare occasion. Does anyone know if the suction cup that comes with the unit will securely attach to the inside of the windscreen?
On a bike, I would not suggest the windshield mount used for a car.
If you do not want something permanently mounted to the bike, your options are limited. A RAM mount is probably the easiest to take on and off. A Techmount would be second easiest. With either of those, you will have a power wire showing when mounted on the bar. And if you want it to talk through the stereo, you'll have a wire running to the AUX port on the radio.
The HD handlebar mount is one of the cleaner looks on a RG, with the wires run internnally to the bars, but you will have the cradle there all the time.
