Google Maps’ offline feature sounds like the ultimate safety net for cellular dead zones. The logic is simple: download the map before you leave, and you are protected. In reality, that "offline" label comes with some frustrating fine print.
First, turn-by-turn navigation is strictly built for driving. The moment you leave your vehicle, offline routing for walking, cycling, and public transit completely vanishes. While you can still see your blue dot on a basic visual map, the app goes silent right when you need step-by-step guidance in an unfamiliar place.
