My Garmin Edge 800 is no longer recognised by Garmin Express. It is also no longer recognised by / charged by external battery packs.
I recently bought a second Garmin Edge 800 and that one is recognised by Garmin Express without a problem. It is also immediately recognised by /charged by external battery packs. I am using exactly the same Garmin USB cables with both devices. I already performed a factory reset on the Garmin Edge 800 with the issue, but to no avail.
Any suggestions?
