Just use Garmin Express to update map to CN 2015.30. The advance button was missing and I saw no way to install on the computer. I was think maybe you could install from the GPS but I can't find that option in BaseCamp. How do I install the updated map on the computer? Thanks
Never mind, I went back to Garmin Express and found the advance button. I got a different screen for the reinstall and found the advance. Not sure if I overlooked the advance button the first time or you have to do two installs.
