Subject: Garmin 310XTWhat am I missing? I recently bought the 310 and when I try to upload my workouts it doesn't "find" the device. I have it attached to the pronged clip and plugged into the USB port. Nothing. Is there something I need to install? I have been uploading from my 305 for months and never had a problem. I don't remember installing anything specific but maybe I did. Help me... |
