Hi everyone. I purchased the SD Card for Backroads Mapbooks to load onto my Garmin Overlander. I cant tell you how long I have spent trying to do this without any luck. I loaded Basecamp on my computer and finally I think loaded BRMB. Although I don's see any difference in the map showing on Basecamp. I'm trying to load the BRMP on the Overlander and I cant figure out for the life of me how to do this. I find the whole process exhausting. Please help. Thanks
