Another interesting GPS application you can try is if you have a smart phone, the application called "WAZE" which is like a GPS navigation app, but its configured to use other drivers statistics on the road at the same time.. so you get real time traffic routing, police notification, red light alerts, construction and obstacles on the road... all notifying you on the screen as you drive, Ive been using this more then my Garmin lately... Its really cool how if there is an accident on your route it will re-route you automatically to get your way home the fastest route possible. Try it out, its free and its really cool. You can actually see a real time map of stats on waze.com on the live map.
