I upgraded from Garmin 885 to RV 1095. After connecting the 1095 to my computer and downloading system and maps my Basecamp shows only major highways, no local or county roads or streets. I have selected Highest detail pulldown, deselected Basic Map Only under View, tried zooming in and out. The Library shows my 1095 properly. What am I missing? I'm sure there must be a simple answer as both Basecamp and my RV 1095 are useless this way.
