Santa brought two new GPS units to my house for Christmas, so I was thinking about recycling my old Garmin Nuvi 200 to my 01 Triumph T-bird. Ebay has several handlebar mounts for the Nuvis that look promising, so that part should be relatively easy to remedy. My main concern is rigging up a 12 power supply to the bike for the GPS unit. Are there any special considerations that I need to pay particular attention to? Should I just connect a cigarette lighter receptacle to the battery or fuse box to power the unit or dispense with the plug-end of the power cord and connect the unit directly to the battery/fuse box? For the sake of arguement, I use a full face helmet, so sound quality really isn't a huge concern but being able to see the GPS screen cleary is a necessity. finally, how do you "weather-proof" a GPS unit on a motorcycle short of taking it off when it starts to rain? Any ideas you guys have tried would be greatly appreciated.
