🧭 Battery-saver navigation

GPS updates while this screen is visible. Lock your phone between checks to save battery. Offline use needs a downloaded route and map; battery life and retained browser storage vary by device. Test in airplane mode before departure and carry a backup.

⚠ No offline map yet — download your route area under “Before you go”.

📍No route loaded — you'll still see the map and your location. Load a route for progress + off-route alerts.
