I have a Garmin GPSmap 60CSx. When I'm navigating (with auto-zoom mode turned on), the map page correctly shows the map at an appropriate scale. (E.g., if the target is 10 miles away, the map is shown with the 8 mile scale.)
However, if I switch to another page (by pressing "page"), and then switch back to the map page (by pressing "quit"), the map is no longer drawn at the correct scale. To fix this, I need to "reevaluate" the route.
Is this a known issue? If so, how can I stop this from happening? I.e., how can I ensure that the map gets drawn at the correct scale (for navigating), each time I'm at the map page?
