Hi - I have a Garmin Edge 800 that connects to my iMac through a USB lead. The Mac is not recognising the Garmin when i click on upload and therefore I am unable to download any recent rides from my device. When i go to download recent activities the only device the Mac recognises is an old Garmin 405 watch which is no longer connected to the machine. I have tried buying new USB leads and still no success. Can you recommend anything that will help to rectify this issue please.
Thanks
Martin
