I have a Garmin GPS that I plug into the cigarette lighter in my car that i when i travel. How can i connect this to the power system in my 2012 Honda Goldwing. It is one of those portable kinds that you stick to the window and then take off when you are done. The built in system was too expensive. Any ideas? I would think there might be some kind of after market harness kit. I dont want it permanently installed...just be able to plug it in when i need it.
