I barely know how to turn my GPS on, and do so only a couple times a year and only to see how far I have walked.
Other than that it is all by map and when the fog sets in, in deep timber or you're when hiking somewhere new in the dark, a compass is invaluable.
I use a GPS all the time. It does some amazing things. However, I try to stay proficient with a compass and map and carry them in my pack. It's easy to get complacent with them, though.
