Hi,
I have an Oregon 450 with Backroad Mapbooks BC V3 and Garmin Western Canada Topo installed. The Topo is on the device and the Backroad is on the Card. I am running Windows 8, 64 Bit. I installed Basecamp 4.2.4.
After installing I reboot my laptop and then connected the Oregon. The problem is Basecamp is not showing either of the device maps. I can only see the Global map in Basecamp. With previous versions of Basecamp and Windows (7) I had similar issues but these were fixed through this old thread: https://forums.garmin.com/showthread.php?27291-Basecamp-not-showing-any-of-my-Oregon-s-maps
Now however nothing I seem to do works. The maps on the device work fine when using the device but they do not show up in Basecamp. When connecting, I do see a quick status bar attempting to find the device maps but it doesn't seem to finish. I've tried installing older versions of Basecamp but that doesn't help.
Any help would be much appreciated!
