BTW, also being a caver, GPS doesnt work in caves, compass does.

A GPS really doesn't even work that well in the woods. I have 2 and I
always carry them on vacation (Idaho, Alaska, the Dakotas and Wyoming)
but you have to climb a tree to get enough satellites to establish a
fix. My wife was constantly making fun of me waving these in the air
trying to get 3 satellites.
They do work OK in the desert.

Does anyone have any experience with working the GPS from the centre of
a moving vehicle? Does it need to be near glass to receive signals?

Dave, they do need to be near glass if they only have an internal
antenna. There are models that have a connector for an external, and
the external itself costs around $25. There are also units made that
have the external already with it. Especially on trips to places I've
never been, I don't know how I ever got along without a GPS. And
before Mapquest, how did I EVER know where I was?
