I bought a Tom Tom because it was a good deal and had really good reviews. The Magellan I used to have was a million times better. The Tom Tom has got me lost several times already, and I have only had it a few weeks, So I bought the magellan 1440. The 1440 has been perfect so far. No complaints at all.
I sometimes drive close to 1000 miles in a week, and it is very important I get to where I am going on time and the magellan always gets me there on time.
