Hi guys, for those of you looking for Nav options, I highly recommend the Magellan RoadMate 700. A bit pricey... Costco has them for about $1,000. It has maps of the US and major Canadian cities already loaded (no need to upload each trip) Large color screen, Voice directions (not voice commanded, it just calls out upcoming turns), and also lists points of interest. You can also bring it from car to car. Mounts to the windshield with a clamp-type suction cup with extension arm. Go to Magellan to check out the full specs.
