I don't think it's polite to ask them to do that. You are however free to ask for bearings. It used to be part of the Cross Country Test when I was a boy, if I remember rightly all that time back.
If you're lost you can ask anyone anything, switch to 121.5 if necessary.
Trouble is the whole thing is geared to spending half your life proving you can navigate with nothing else but a compass and a kleenex tissue. Next minute you've got triple INS and you never need to use your finely honed skills ever again...
