I bought a Garmin 660 earlier this year and love it. It's cool to take a shortcut, get lost and let the Garmin get you back on track. Every now and then you'll run into a situation where it's maps aren't very accurate... especially with new roads and construction. On vacation we turned onto a new overpass and the Garmin totally freaked out. The little car icon was way off the road spinning and and the Garmin was saying recalculating...recalculating...recalculating...recalculating...recalculating...
