Summary: I really love the 720. I have tried the Garmin Nuvi and just didn't like the software nearly as much as the TomTom. Entering addresses is really fast and you only see towns in the state you are looking in. This means no more having to scroll through 30 different Springfields to get to the one you are searching for.
Summary: This thing is so cool, it's far beyond what I imagined. It has voice recognition that I didn't expect. It has mp3 player that can play through the speaker or the FM radio in the car. If you intentionally or make a wrong turn, it will tell you where to turn to get back on your planned route. The only thing bad, is when you drive a route that has been changed, it will steer you wrong, unless you get updated maps. TomTom wants $60/year for updated maps.
Summary: This GPS appears to be well built. Fit and finish is great. It looks and feels like a well built device. It's pretty easy to use even without ready the instructions. I would definitely buy it again.
Summary: Have another brand GPS for the car but needed one for the truck. Love the convenience of speaking the address/POI, etc. Easier to see easier to work and I find myself arguing less with this one than my other. (:>) I definitely recommend the unit!
