Summary: Had to update this on the Garmin website, that took 10 hours. Then loading the maps took another four hours. But so far it seems to be working and for the price I'd say it's worth it. The mount is totally useless in my Suburban, when mounted on the windshield it is too far away to see whats on the screen. And if you want to use the vehicle charging cable the unit MUST be in the mount. The charger cable plugs into the mount, not the unit.
Summary: I like the fact that I can get around without relying on anyone to give me directions. I hate the fact that sometimes the Garmin StreetPilot C320 cannot find satelites, which makes it impossible to rely on the Garmin. Another problem, is that the window mount constantly falls off of the window.
Summary: When we got the Garmin (re-furb) it didn't work, wouldn't come on or anything even though we plugged it in to charge as outlined in the directions. we contacted the company, 2 days later we got an e-mail that says we should contact Garmin they might be able to help. we finally found directions on Garmin's web site for a different model and found out that we had to take off the front and re-boot the system.
Summary: I found one of these for $200, and based on the reviews I figured I'd be pleasantly surprised. I thought wrong. Not only are the maps highly inaccurate, but it doesn't give enough notice on when to turn, so missing turns is quite common. The routes this thing takes aren't usually the optimal choice, and it likes to avoid the highway even though it's on the default settings. So you end up taking a ton of back roads that really slow down your trip.
