How do I transfer waypoints from my Carbon unit to an H2Oc unit.
I’m not 100% sure but you may not be able to do that. The Carbons are fairly new and the H20C is a much older hand held unit. It may not be possible to go “backwards” like that so far.
I have both an H20C and a Carbon and I was able to transfer waypoints from my H20C to my Carbon a couple years ago, but that’s the opposite of what you’re trying to do here.
