Thread: Garmin GB Discoverer Great Britain National Parks 1:50K

Hmm, well I tried the number generated by the checksum and that didn't work. I think the card may have had it though as I formatted it it earlier and it is no longer showing any hidden files.

I have used the (correct) id of the garmin unit instead and it now works. Silly me thought the number inside the battery flap was the garmins id.
