using GPS in a 1955 Packard

I like so many others have become dependent on using GPS to get to a location. The problem is with the negative ground in the 55 Packard electrical system the GPS will only stay on for about 2 hrs then die-is there any way to rewire the lighter to have it + instead of - or does someone else have a solution?
