When using the destination by address the system consistantly misplaces the location on the map and occasionally tells me that a known address number does not exist. I had Navigation in my 2002 STS and never had this problem. I am going to bring it to the dealers attention but wondered if anyone else was having the same problem.:hmm:

I had noticed a problem with that on a friends 05 Crew Cab Chevy. It would tell you things were there that we not. When we were driving through Memphis, they told us the exit we would need was coming up on our left. Little to say we needed to turn right. I think it is a software problem.
