I have tried to delete everything on the unit, hold top left corner and clear on boot. It has a formatted sd card with nothing on it but a garmin/gpx directory.
I add a single waypoint on the unit and connect to BaseCamp 3.2.2. I see the new waypoint along with the 3 default Garmin location waypoints.
However, if I select the new one and edit I can't change anything. i.e. If I wanted to change the symbol I can't select a new one since the arrow for the dropdown list is grayed out. Same with delete or any other edits.
I can copy them all to My Collection and edit there and then copy back and it works but I have read the Oregon allows edit directly on the unit. Firmware is latest for the 400t 4.20.
Does anyone have any idea why the unit seems to behave in "read only" mode?
Thanks
