I downloaded all of my Nav data to the SD card on my unit and then organized and renamed all of my waypoints. When I uploaded to the CD card I chose replace. When I inserted the card after unit startup, I got the unit to accept the new data. My problem is that in the birds eye navigation view the new waypoint names appear. In the 2D view the old names (just numbers) appear. How can I fix that? I'm using a transformer to power my unit.
