as a owner of a service company , we have to venture into area that be unfamiliar . laptop be cunbersome to operate in the car and that be far more than what we need and mapbook be outdate before the ink dry . the Nuvi be purchase in April 2010 and have prove itself to be a perfect choice and fit for we need . the setup be complete and good to go in 10 minute . every feature so far have prove itself just as advertise . it have be use , without error , thruout the California Central Valley town and extensively in the so . cal beachfront area of L.A. \/ Orange and San Diego Counties . I would recommend this tool and would certainly by one again . the one minor issue be that the Nuvi will not charge if leave in the direct sunlight -lrb- such as a dashboard or windshield -rrb- and plug into the power port of the vehicle . a safety feature prevent charge so that it do not overheat . we learn to work with this quickly and do not have any other issue with it .
