Well mine doesn't seem to do anything clever (it's a few generations old
Garmin). It shows which channels its tuned into and fresh out of the box
it'll cycle betweeen 1-12, 13-24, 25-36*, until it finds at least one
satellite, then it starts whittling.
Okay, interesting. I'd guess things are quicker now.
(* not sure if it goes up to 36, and not sure what the channels
correspond to exactly)
It'll be the number of the satellite. There are 31 at the moment, and
could be more - i don't know if 36 is a design limit.
