I have a Z2 and pretty much all fast food chains, gas stations, and lots of other things are WAY OFF. Even addresses that I try to navigate to are either way before or way after where the navigation unit says they are. Will the CNDV-800HD or any upgrade pioneer offers fix this? I mean it's almost to the point where using the navigation to get to a specific location is pointless because all it's good for is getting you to a general location, and i can do that without any navigation unit. Really all i can use it for now is to take shortcuts to local places just because i have an aerial view of all the roads around.

Thanks.
