Fleurya's comment is the norm. You're in a world of hurt if you choose that outfit.
Odd, I haven't experienced this "world of hurt" with either of the Magellans I've purchased. Granted, I have not needed to contact their tech support since both of them worked perfectly out of the box and have continued to do so ever since.
TomTom, on the other hand, I have needed to contact. My experience was absolutely awful. After waiting 4 hours for the unit to receive satellite data (outside, in clear view of the sky), I finally broke down and called their hotline.
I sat on hold for 45 minutes, only to be abruptly cut off and told that the lines were now closed, I'd need to call another time. In my book, that is terrible customer service. If the queues are close to closing, they should stop taking calls, but finish those customers that are in queue.
When I finally did get the unit to acquire the satellite signal (after multiple reboots and fooling around with the software), it seemed to work fine for a day. The following day, this time starting up at a different geographical location 30 miles away, the unit went back to not being able to acquire a signal for hours at a time.
My Magellans were exactly the opposite. Out of the box, *and indoors*, both machines nearly instantaneously acquired the satellite signal and were basically plug-and-play.
