Inventory Pass/Fail

 

On my 855, when I view the undocumented Inventory page of the diagnostics, it lists all of the software and versions on the machine, as well as status (Erased, Pass, Fail, or a Number).

For both of my maps, it always shows Fail, despite the fact the maps are freshly downloaded from Garmin support. They work fine.

Does anyone know the significance of the "Fail" indication?
