VMG?

I have been using openCPN with my cmap charts. So far it seems like a great program. But I have been trying to find the VMG to the next waypoint. How do I get this? Also is the BRG and RNG in magnetic degrees? How do you change from true to magnetic? What does RNG stand for?

Cheers.

Re: VMG?

Dennis...
VMG is in the box labeled VMG.
No magnetic.
RNG = Range (= distance to the next waypoint/Last waypoint in thr route, depending on whether you are switched to the current leg or the whole route mode)
