Under maps I in Basecamp I habe Global Maps checked. I am using city navigator installed on my GPS.
Without City Navigator in your BaseCamp then you cannot create routes to get turn prompts.
You may be able to get your unit to calculate the route for you while you ride. However, that is a high risk to follow a route before you check it first. I would not recommend that.
As for the routes on the left, I don't see any campgrounds with a tent icon next to it nor do I see a bicycle.
I see a small bicycle symbol next to each route name in the screen capture your provided earlier, in the bottom left. Do you not see that?
Try to load the original file that you downloaded from Adventure Cycling. That should have the waypoints for campground with a tent symbol.
How do I get City Navigator to run in Basecamp? Do I connect my GPS for that to work?
I do not know of any way to get the maps from your device to BaseCamp.
Your best bet at this point, depending on when you bought the City Navigator SD card, is to return it and buy the same product only on a DVD or download it. That way, it will be installed on your computer. From there, you can transfer the files onto your device.
