This was installed in our SMB when we bought it. The maps were a bit out of date, and the cost to update the maps was almost as much as a new system so we went that route instead. We only had the Western states DVD (map), and there should be at least one more DVD of maps. SMBw removed this system and installed our new one, so I can't even say if that DVD is in the player anymore. This might be a good parts system to someone who already has the same system installed.
SMB-less as of 02/04/2012. Our savings account is richer, but our adventures are poorer.
