I bought a TOM TOM online at amizon, which by the way I will never buy from them again. They used the bait and switch to sell me a TOM TOM that was supposed to have lifetime traffic and maps. When I received it it had neither. I called TOM TOM and after 4 calls the supv. finally agreed to update my maps from 2009 to 2011. The cust. service people were very helpful but it was sad that after updating my unit it worked worse than before. I had no problems with the unit before I updated it, it worked great, but didn't know a lot of the roads i was on. Now after updating it it shuts down unexpectedly or it doesn't know where it is. What good is a gps unit if it can't tell you where you are. I really like this unit over Garmin and the Magellan one I had before but I just wish I could get a unit that works all the time.
