My 4x4 is a Subaru.
my friend recently got a Magellan road GPS that does directions to locations, points of interest etc. (the kind that you use on road trips that sticks to your windshield) I really liked that for using in the car. It doesn't do the bread crumbs thing, though. Is there a good combo out there that is meant to stay in the car, that would be good for doing bread crumbs and saving the trails that you go on, or are you just better off getting a handheld for that like the eTrex or something?
