An offline map protects against missing map data, not every navigation failure. Download the complete corridor and destination area, update it shortly before departure, and test what remains available without a network connection.
Download an area in Google Maps
- Connect to the internet and sign in to Google Maps.
- Tap the profile picture, then Offline maps.
- Choose Select your own map.
- Resize the box to include the origin, route corridor, destination, and reasonable detours.
- Tap Download and wait for it to finish.
Google's offline map instructions note that offline driving lacks live traffic and alternate routes, and that walking, cycling, or transit directions may be unavailable. Availability also varies by region.
Download an area in Apple Maps
On an iPhone with supported software and in a supported region, search for a place and use Download, or tap the profile picture, choose Offline Maps, and add an area. Adjust the coverage before downloading. Apple's offline Maps guide explains storage, automatic updates, and regional limitations.
Cover the route, not just the destination
A small square around a hotel will not help on a 300-mile approach. Include major junctions and the area where you might leave the highway for fuel, charging, food, or lodging. For a route near the edge of a download, add a second overlapping area.
Test before the trip
- Confirm the download is complete and note its update date.
- Temporarily disable Wi-Fi and mobile data while parked.
- Open the map and confirm the origin, destination, and corridor remain visible.
- Check whether the required travel mode and directions work offline.
- Restore connectivity after the test.
Know what offline maps do not replace
- They do not repair weak GPS reception in tunnels or garages.
- They may not include current traffic, closures, or newly changed businesses.
- They do not guarantee search results for every place.
- They cannot call for help without an available communications service.
- They still require battery power and enough device storage.
