Have owned Tom Tom and Garmin, and Garmin is definitely the best. Tom Tom does have better sound but that's not really an issue anymore because you can play most of the new Garmins through your car radios speakers. Make sure you look at the Nuvi's, they are one of best Garmins out there, bar none. They use the latest satellite technology and track to within 3 feet. I just picked up a Nuvi 660 last week and it comes on Friday. I'll be writing up a full review in a full weeks after I put it through the paces, but I'm sure it will be at least as nice as the Nuvi 350/360 is so it should be a winner
