a lot of newer cars will have GPS build right into them some have already been release to the public, as will cellphones have them build right into them so the police or law enforcement can locate them faster when they are in trouble on the road or outdoors like in hunting trips.

think buying a GPS unit is a waste of money DD, but hey its your money personnaly buy something for your family would be better then a GPS unit can gave fun time out some place. rent a GPS see what it all about before buying one be better.

to rent a GPS unit check around some boat shop or boat repair location most have GPS units to rent as will selling them. some are portable units as will build into the boats
