I use mine for backing up dead reckoning technique, and as such, I use the eta at next, dist to next, and pointer (as my brain does become a little dulled up there).
Yawning dog, take the point about next waypoint name. A simple mistake, but one easilly made I guess.
I've got the best use of mine since I started playing with the functions whilst being a passenger in a car. Could make the odd f%^k up, without upsetting anyone.
At the moment, I'm trying to get to grips with the freeware
here but yet to find one that suits my needs, guess I'm going to have to fork out £70 on a pofessional syste,m.
