Not to de-rail your question too much but-
I have discovered the "map" feature on RC is good. Not great. The GPS system on RCwill always show you where you are but, the markings on trails are not so good. Some don't match trail names or numbers.
It's still better than running out of cell coverage or not installing the correct map on Avenza. Or, having to pay money to Gaia or others for additional maps when your map coverage runs out. RC will always show you where you are at. The name of the county road or trail may be wrong, but you know where you are at.
The group ride function is incredible!!!!! Love it!! Best feature on RC!!
Any more, I bring a paper map and/or an alternative map system (iPad) to compliment or supplement Ride Command.
Drop way points and track your ride as you go.
