5 years ago I bought what I was told one of the best GPS's on the Market at the time, was the Garmin nuvi 350, but like all electronics they become obsolete quickly and are replace with higher advance gadgets, the garmin was good for about 2 years then it always said that I need to update maps ( More money of course )and after not updating i think it purposely would pee me off by sending me in circles, or either have me pull to the side of road sit still for 5 minutes in order to receive a Sat. signal,........
so instead I now use this GPS as a MP3 player and a digital picture storage unit,

and went and got a cheaper GPS Garmin nuvi 250 and it works better then the more expensive one ever did,
Hey my same Garmin problems-- drive in circles...I too now have a Tomtom..Still use the garmin, just cannot take it serious. It has put us thru the woods too.
