For those riding front fairing bikes, you can plug your GPS into an unused 12v. source and ground behind or near the headlight. Remove the front fairing and look in that area and you'll see two wires, one with black end and one with red end. My 550 Garmin plugged right into those wires on both my 2008 UG and now my 2012 Limited. Then it has power depending on position of the ignition switch. Used the same method on friend's bike too so check it out.
