Some of the newer head units will retain settings for a minute or two. I was thinking a battery tender through the cigarette lighter but some advise against it. I think a 12v motorcycle battery may be your only option. I'm not sure if the risk of using jumper cables between the batteries is worth the risk of sparks flying.

There is a 12V device you can purchase that goes in the lighter slot. I think its from Radio Shack. It will hold the settings on of my friends has one. When I changed mine I did not loose anything but I did the swap in less than 4 minutes.
