Garmin Forerunner 645 Owner’s Manual Now Available.
I found it, for the first time, last night.
I haven’t looked through it yet. But, wanted to make sure that YOU knew about it.
The Garmin link is this …
Enjoy. With luck I hope to have one in about 8 weeks. I am NOT getting one from the first batch. Learned that, to my cost, with the Garmin Vivoactive 3.
