Hi
I have downloaded the garmin discoverer maps and put them on a SD card and it works great on my Dakota 20
My friend has just got a new one so we did the same for him, put it on a SD card same way as I did mine with SD card serial number etc well it justcomes up saying card locked, and will not work but the strange thing is it will work in my Dakota and but not his
they have both been updated to the latest software but the maps will not work in his but do work fine in mine
has anyone an idea why we can not get it to work on his?
is my dakota unlocked somehow if so how do we do the same to his?
hope someone can help please
