Tour guide?

AREAMAP

Think of what helps you navigate a large space like a park or museum—it’s not a person, but something you might hold or see on a wall.

This clue plays on the idea of a "tour guide" as something that helps you navigate an area. Instead of a person, it hints at a "map" of an "area," combining the two words into "AREAMAP." The question mark signals a pun or wordplay, suggesting the answer isn’t literal but a clever twist on the phrase.
