Is anyone else experiencing problems with their NAV system? I took a trip up through Pa. last weekend and their were times that it was wanting to send me down minor two lane roads when I was wanting I-70 and the Turnpike. It couldn't even find York, and I know that's been there for a while. About a month ago I was going from Columbus Oh. the Cambridge and it wanted me to travel some road that ran parrallel to I-70, then threw a fit when I got on I-70. All the settings are correct. It seems that the problem happened after I got the update disc from Dodge and downloaded it.
