I recently use the device for a trip from New Jersey to West Virginia . the Garmin Nuvi 350 take I from point a to point b without a problem . it even navigate through back road to several state park located in the mountain . I be especially impress by the way it navigate through multiple highway that either converge or split into other highway . the audible navigation be clear and the system be quick to recalculate a route when need . it be understandable that not every roadway or address can be properly list . perhaps municipality and\/or county who already gather local mapping information can lend a hand by submit up to date information so consumer can have the latest datum at a reasonable price . at a cost of $ 670.00 , Garmin could have offer the consumer at least one free map update when it become available . I recommend this device to anyone who need or like to travel .
