Nothing is 100%.

Whats is your choice and why?

Can a destination be reviewed on screen with any detail before getting there? Are surrounding streets visable?

I currently use Goggle Maps on my PC prior to driving in but its not real convenient once your moving meaning i,ve put it away.

Im thinking about the Garmin Nuvie 360.

Is there software out there yet thats commercial oriented?

Sure would appreciate hearing your experiences with your GPS.
