I have two GPS units. I'm trying to decide which one I want to put into my new truck. I've been driving with the Garmin Nuvi 2557 in my personal truck and the TomTom Start 720 in my work truck. Since my work truck is going away in the next week. I'm trying to decide which of the two I should use in my new truck.

Just would like to hear what everyone else's opinions are between the two.
