I get lost with GPS, formal maps, and verbal advice.
I don't pay attention enough to be able to keep focus on what someone is telling me. Sometimes, I forget to turn the volume on for the GPS, so I'll keep driving fifteen miles past where I was supposed to take an exit. I'm hopeless... until, someone draws me a handdrawn map with little landmarks and a few arrows. THEN, I figure it out just fine.
Verbal directions go in one ear and out the other, written directions without a map to visualize the route are not my favourites either. I can't decide between having a map with charted route or a map with location of destination indicated. In case of the latter, I do love reading maps and find my own way of getting to the destination. But if it's an area I have no previous experience with, then having a map with a route pointed out might be the best option, that is, when the route is made by somebody familiar with the area and who knows the best way to get to the destination. If it's computer generated, then I'm not quite sure I trust that it is the best route. Ahh...ok...I'll vote for the latter, at least it might be fun doing it this way.
I like to have verbal directions first because as they are spoken I get an aerial view of my car with what's being said in my head. Then I like to write them down myself because it reinforces the picture of the map in my head. Then I'm there.
