If you use the regular downloader, it should give you the option to choose the SD card if the drive is full.--I'm not anti-social, I just don't like stupid people.
Thanks for the response. When I open the garmin app to download, it only gives me the choice to download to device, or my computer. I will try the computer download and then move it to the micro sd and see what happens.
You have to click the "Options" button, bottom left corner. It'll be in the first few screens.--I'm not anti-social, I just don't like stupid people.
