Query: awesome GPS, I did my research, it paid off. The Garmin NUVI is top class

This GPS is the best. Spend a little extra $$ to buy a good gps and you won't be dissapointed. If I had one "bad" thing to say, it would be that the voice can sometimes be a LITTLE hard to understand, but think of all those crazy words and road names she had to know! Everyone talks differently, so it would be nice to be able to select different voices (like you can on an apple computer). But overall, it is insignifigant compared to this awesome GPS. I'll never have to carry a map again- even if I go past my turn the thing can get me back to where I need to go. City or rural, you name it. I don't know why I didn't buy this a long time ago.
