Summary: The devil is in the details. The unit works as advertised, but the "lock ups" are something I've never encountered before. I have a built-in unit in my car, and it has never locked. Mine 600T locked so severely once, I couldn't even turn it off or reset. That brings up customer service. I called twice, and my wife called twice, and neither of us could understand what the reps were trying to say.
Summary: We purchased the Magellan RoadMate 6000T for a trip cross country. We arrived with only one misdirection, which Magellan quickly recalculated and sent us in the right direction. We love this unit, but it will NOT backup our information. I tried 3 different SD cards and had Magellan Customer Service walk me through the process several times.
Summary: It does a great job of navigating, but my first unit that I received for Christmas would not allow me to save my created addresses and system preferences to a back up memory card. As a result, I had to rebuild all of my data each time the unit locked up (fairly frequently). Additionally, the "repeat last instruction" feature didn't work. Called tech support, and they couldn't help me, so I exchanged the unit.
Summary: Have had this unit for about 3 months now and have to reset it maybe once a week which is a pain and you lose your data at times when you do that. It locks up or a feature stops working like the voice commands and then you have to reset. The bluetooth is not worth the extra money since the speaker is too low at top volume. I can't see any benefit to the picture or MP3 options either, so I'd go basic if you get a Magellan RoadMate unit.
