I have tried to get basecamp to read a pre installed on sd version of city navigator 2008 to use to plan routes on my Edge 800 and Gps map 60scx.
The card works fine and has been used in both devices and I know from research the latest versions of CN can be read by basecamp. The .img file is in a garmin folder and I have tried making a copy on a different sd card but this was still not showing in basecamp (although also usable in my edge 800).
I am guessing that basecamp will only recognise newer versions of City Navigator?
