I used my free map update to download the 2010.40 map update when I first purchased my Garmin. However, lane assist does not work and the 3d maps do not work. I checked "maps" and saw that both the 3d and other 2010.40 is checked as well as having the view in 3 dimensional. For some reason when I go to mapsource to retrieve the maps or when I go to mapinstall it says that their are no maps on the device. Doesn't make sense to me and I've been at it for hours. Any help would be appreciated thanks.
