This was a warranty replacement for my Genius back in August so I have no idea what Garmin will say or do to help, but in the new year I will try them - I am out of the 2 year period though.
Due to injury I set it up and did a 10 minute test to make sure it was ok. Seemed to have no issues then but I probably had music on and missed this noise.
It’s sat unmoved ever since covered up - no impacts, not dropped, no bike on it.
Popped bike on today and there is a scraping noise, looking in the vent on the rear the copper disc edge is really out of true as per video below.
Any ideas before I try to warranty?
