Hi,
I have a subscription to Birds Eye and have several Ordnance Survey map areas on my GPSmap 62s. Yesterday I copied another map area (Ordnance Survey) from Basecamp to the 62s. The area shows properly on Basecamp view, but not on the 62s. If I zoom all the way out I can see that there is a map there, but it's too far out to be useful! As soon as I zoom in it disappears. The new area is immediately alongside an area I downloaded previously, and that previous area is visible and useable. I have used underscores instead of spaces in the map name.
Thanks.
