Relative newby here having trouble with Basecamp, and hoping someone can offer advice. The computer that I originally used to load various maps into Basecamp and my GPS has died. I installed Basecamp on my new computer and all my old maps are still on the GPS and show up in Basecamp, but I can't find any way to have those maps show up in Basecamp when the GPS is not connected. In particular, I have a unlocked .img map that I'd like to have show up in Basecamp. By Googling I've tried all manner of utility and virtual drive methods for having the maps show up in Basecamp without the GPS attached but none of them work. I have a feeling I'm missing something simple. I have the latest version of base camp installed on my PC and the GPS is a Garmin Oregon 600. Thanks for any advice.
