Don't buy Cobra GPS. I had nothing but trouble with it, and their tech support simply stalled me until the warrenty was out. It just kept quitting.
By contrast, Garmin GPS has worked great for almost two years now.
Kinda the way I felt about my old G3 Nextar - no problems, just no map updates. Replaced it with a 7100 Navigon and have been extremely pleased with their great product support, quarterly map updates ($55 for 3/yrs. from Amazon) and service in general not to mention their free traffic bulletins where Transguide is available. I had a problem with software and they walked me thru resolving and also had suction auto mount that went south with little use and the aired me a new one, no questions asked.
