I got the Garmin c550 last week after a frustrating excursion accross the state and accross Boston.
The c550 is a very good GPS. It tells you the street name and when to turn.
Like Capt Al said it wants to take you on the highway most of the time.
When I deviate from its planed route, it recalculates.
I think it will be a good time saver between service calls. As long as our dispacher can give us the correct address.
