I need help. I recently bought a Garmin Zumo 220 for my '05 R1200GS. I was told that I can run it off the GPS battery and recharge it at home using a wall adapter or hard wire it to the bike battery by taking off the tank and running the wire from the handlebar to the battery. Yesterday, while at a BMW shop, someone in the service department told me there's no reason to run the wire(s) under the gas tank to the battery. He told me there is a plug-in right around the handlebar, which will power the GPS on/off when the key is in the ignition and turned on. Anyone agree or disagree with that statement? Any advice on how to set up my GPS to run off the bike battery? Any help would be much appreciated.
