I'm on my second Magellan in car. The first one still works, but it's maps were getting old and I was getting tired of driving on roads that didn't exist.
it was cheaper to buy a new one with lifetime maps than to update it.
I don't use the new one much. On long trips I'll put it up so I don't have to worry about getting on a phone call and missing a turn, and have the time remaining on screen is nice. But for my day to day, in town stuff I just use my phone.
