i hard wired a cell ph charger into my dash of my car , I used a cheap cigarette plug charger, can be mounted / hidden anywhere, use some tape & hot glue to water proof and have fun !

Did your GPS unit have some sort of power cable or USB cable to run off of the cigarette lighter for external power? If you only have a wallwart plug in charger, you may want to get an inverter that plugs into the cigarette lighter and gives you the standard wall outlet to plug into.

It is actually going on a dirtbike if i can get it to work so I don't have alot of room and I just want to hardwire it in the GPS cause I have a new one and I'm just trying to mess around to see if i can do it
still strap on an inverter, maybe http://www.harborfreight.com/automotive-motorcycle/power-inverters/200-watt-continuous-power-inverter-66967.html
