i just found out last night there is a bug with the initial release of the download of CN 2011.10. Google or visit Garmin's support website so you can download the updated 3D map file which will resolve this issue. This affected anyone who downloaded CN 2011.10. Friday and before. Mine wasnt affected. Still, another reason to wait for the most current release of maps (usually a few days after the download is first made available from Garmin)
