What to do if your [sic] lost?
Can't speak for everyone, but as for me, I use the radio. I tune it in and see what language the local pilots are speaking, then I take it from there with my knowledge of European geography
Seriously, apart from what has been said about GPS/navaids in general, get used to having someone on the radio all the time (RIS/FIS/etc). Then if you're lost, they'll tell you
