I have every problem mention in the other review but I want to add that the Palm V seem too slow to handle this unit . it be particularly slow when zoom in and out of map . I have a dvd base nav system install in my car which I love so I may have too high standard for this handheld unit . I believe the problem be mostly software base however . basically , this product be not ready for prime time . btw today be Oct. 2002 . I try this system out in 2000 so I do not know if there have be any improvement
