Daft GPS question...
Hi all,
Not much of an idea about GPS but looking forward to buying one and learning the basics. Drawn between eTrex 20 and 30... My question being, today I played around with them in the shop and noticed that as I moved around in a circle, the blue waypoint marker on the eTrex 30 moved in real-time, but on the 20, it just remained static - in fact it didn`t really seem to move at all, so I`m wondering how you`d use it? That and the `compass` on the 20 didn`t seem accurate at all, not much use... maybe the eTrex 20 showroom model wasn't properly configured? I note that the 30 has a 3axis compass, could this perhaps explain the difference? Any ideas?
:confused1:
EDIT; I also read about a "sticking issue" with some of the lower end Garmins, that if you move under a certain speed (ie slowly) it will not update... could this have been the issue with the eTrex 20 in the showroom, i.e. it was just not updating itself and hence the waypointer was left static? They were tied down to the counter so could not walk around with them...
PS... does anyone know if either unit power from USB?
