do the antennas have to be 'pointed' at the sky, or does it not matter?

Not quite, it depends on the type of antenne, GPS Mice and similar obviously can be oriented in only one way, CF type receivers are designed to be used in a variety of orientations, in a PDA they will be vertical, in a laptop then mwy be horizontal.

Oh damn, i have put my mouse upside down on the inside of the front windscreen right at the top, but it still seems to get 9 satellites. I’ve not driven the car yet.

My TomTom wired receiver is mounted upside down stuck to the back of the tax disc, works fine Smile

well its not working for me, as soon as the car gets on the move satellite count drops from 8 to 3, then to 1 and it stays there, i have had to move it, will wait and see what it does on a longer run.
