I have a Garmin nuvi250 and love it! I paid a little extra and bought the beanbag style mount where you just set it on the dashboard (it doesn't move at all either) instead of using the suction cup on the windshield. My son borrowed it for their trip back to NC when they came for Thanksgiving and will give it to my daughter for their trip to FL when they come for Christmas.
, my kids still just love borrowing MY toys.......
