Garmin connect searches for it but won't find it. It's not my PC, it's been like this for a while, ever since the great syncing / update debacle that occurred on September 7th 2014. I just heard about the aggravation dealing with Garmin so I put it off. Now I'm just aggravated because I can't load routes into this clunker/lemon of a cycling computer.
My phone, Samsung Galaxy S5 sees the 510 and connects and that is it.
What's the deal Garmin people?
