Summary: My Maestro 3100 only lasted a few months before I started having problems with it. It stopped holding its charge, despite always being plugged into it's power source. Having sent the unit in for repair under warranty, I'm compelled to advise Amazon buyers to stay away from Magellan products.
Summary: I had purchased Tom Tom One and later picked up Magellan 3100 and compared side by side. Tom Tom one is atleast 3-4 seconds faster in response to Magellan 3100 on highways , the navigation on Tom Tom is so much better and intuitive than 3100.
Summary: Got this on Black Friday 2007 after having used Tom Tom and would have to advise against buying this. You need to download the Firmware update to get many of the earlier bugs fixed but make sure you do not attach to your PC before starting the update or you may have USB Hardware issues.
Summary: The software is still buggy. It froze up for no particular reason, in the middle of driving. In my recent 800-mile trip, it froze up once on each way. So get a paper clip handy in the car in case you need to reset it.
Summary: My wife and I bought this GPS because we wanted the ability to not use those silly printed out maps and if there was any urgency such as an ATM etc. So we tested this system vigourously for 4 weeks when we started our apartment search in San Francisco.
Summary: When it was working, the product was nice to use and fun to play with. Then, it broke. The arrow on the screen which is supposed to represent your position, stopped updating. I flew down to LA and was hoping to use it to navigate my way around town. Unfortunately, the unit didn't work there either.
