Magellan Maestro 3100 on a 4th Gen specific Bracketron mount that looks much like Lowpro's mount.
We use Bracketron's cupholder mount in the wife's CR-V. I don't like windshield mounts for various visibility, aesthetic, and "security" reasons. The Grab-It holder used with both mounts makes it much easier to remove the GPS temptation from prying eyes...the Magellan windshield mount puts up a struggle when releasing the 3100, but leaving the mount in place.
The Maestro stays on a closet shelf unless we're taking a road trip.
