Did you use and like Street Atlas - Sorry Suckers

The GPS, even the phone provided you have internet access, is fine & dandy. However it is not difficult to get out of cellphone coverage. Having a stand alone onboard program like MS S&Ts is like having case of maps at your fingertips. When it has a GPS receiver better still. The navigator zooms in or out to easily see all options & change the route on the fly, internet access completely redundant.
