i was reading a post about that 430 navigator and i agree it is not good. it doesn't show the road i live on and this road has been in NC for over 5 yrs. it also wants to route me the long way around to a destination. the next thing is they want you to pay $100 or more for an upgrade that still doesn't work. i only kept it because my wife gave it to me as an anniversary present other wise i would have returned it a week after i got it.
