Normally my PC displays a G drive, the 800 unit and an F drive, the card. My routes/courses have been stored on the card as recommended by ...... Now, for no reason that I can recall, the card is no longer visible when logging in. Does this matter and if so how can I recover the card as memory device?
Have you pulled the card out and re-seated it? The Edge 800 sub-forum would have gotten your post in front of more users that are familiar with your device. But maybe someone knowledgeable will see it here.
