Summary: This works in a pinch, but I've had some issues with it. It doesn't always give me enough time to make my turns and it sometimes tells me to turn on a street that isn't there or at a dead end. But, I am glad to have it; it does help.
Summary: i 've had three nuvi two for my cars and one for my rv. each one of them takes an exorbitant time to hook up with sattelites; that's why i just bought the low end of the alpine line. my wife's built-in alpine hooks up immediateley.
