TomTom GO 720

Pros: screen size, keyboard, acquisition time

Cons: SD card install to increase memory is a convuoluted process

Summary: Have now been testing this 720 against a Cadillac CTS factory installed GPS and find:
1. 720 far easier to use
2. Maps much more current with free updates vs Cadillac charge of $500.0
3. screen is just as easy to read as the CTS
4. Recalculation for route recovery fast and seamless.
5. Have a major displacement error in the 720 in that my HOME gps indicator has displaced its marker by 1 street and no amount of effort seems to correct. Will seek TomTom tech support.
Bottom line . . why pay $2000 for an in dash unit that is nowhere as efficient as the 500.0 TomTom portable 720
