An update for the card image I posted earlier:

- My CLA SD card slot does not seem to work with any SD card (including this original Garmin Map Pilot) - may need to go back to the dealer

- When the SD card's Lock button is turned off, the card cannot be read or detected on the PC.
- Can only be read when the card's read-only lock button is engaged (this is how I was able to take an image) - not sure what to do with this card.
