Summary: I would not recommend the Nuvi 250W. I purchased two of these from Amazon and I have been disappointed. They take a long time to acquire a satellite signal. When I was in San Jose it took 5-10 minutes to acquire a signal. I was already to my destination by the time I got a signal. I then took it to Chicago and waited 10 minutes for the signal.
Summary: I bought this when I moved to San Francisco 3 weeks ago, and at least for SF the Garmin is more than a little buggy. Since SF has several overpasses and freeways over streets, the Garmin has trouble when I go up an on-ramp and often glitches, suddenly thinking I'm on the road below. Once when crossing the Bay Bridge it suddenly thought I'd leapt off the road and headed over water, spinning in slow circles ... a situation it didn't correct until I was well into Oakland.
Slow acquiring saatellite signal & clumsy User Interface
21 September 2007
Summary: Takes up to 3 minutes to acquire a signal even under clear sky. Sometimes navigation locks up for no reason. I do not like the user interface because once you are deep in the menu you have to back out one step at a time. The "STOP" button is at the exact position of the "BACK" button so I sometimes end up stopping the navigation when I just hit "BACK" once too many. No alternative way to sort POI's and Favorites.
Conclusion: Ayant effectué un tesr sur un trajet de 15km j ai vite été trés trés déçu du gps!! temps fou pour le recalacul, en ville ne me dit dit pas d aller à gauche où à droite et etc!!! j ai donc renvoyé le tout a pixmania! je le déconseille!!
Pros: ECRAN LARGE
Cons: Pas preci, temps monstre pour le recalacul !
