Hi . Had my Garmin Edge 1000 for a few years now but it's gone mental recently. On turning the device off it automatically reboots just to the initial "Garmin" screen. Along the bottom of the screen it says "Transferring to mass storage..." but that's as far as it will go. It just stays like this until the battery runs out. My PC's USB no longer recognises the device so I can't link it to Garmin Express. I've tried doing a force reset, but that doesn't work. Any ideas anyone?!
