Driving toward a national park or a rural stretch of highway often means the cell bars disappear right when directions matter most.
Google Maps offline is the answer: download the area you need while you still have a connection, and the app can keep giving turn-by-turn driving directions even without signal.
This article covers how to download an offline map on iPhone and Android, how to find and update it later, what offline mode can and cannot do, and what to check when it stops working.

🔍 What To Check Before You Leave
Before downloading anything, confirm the basics so the download actually goes through.
Offline maps need to be saved before you lose service, so planning ahead matters more than reacting once you are already in a dead zone.
First, make sure the device has a reliable internet connection, ideally Wi-Fi, since map downloads can be large depending on the area selected.
Second, check available storage space on the phone. A download that covers a whole region will need more room than a single small town.
Third, confirm you are signed in to the Google Maps app and not using Incognito mode, since downloads are not available in that mode on iPhone.
Finally, think about the entire route, not just the destination. If a detour or alternate road falls outside the saved area, offline navigation can fail partway through the trip.
💡 Key point: Offline maps only work for the exact area downloaded, so it helps to select a generous boundary around the planned route, not just the endpoint.
⚙️ Step-by-Step: Downloading An Offline Map
The core process is similar on both iPhone and Android, though menu wording can vary slightly by app version.
Here is the general flow for downloading a city or area as a whole:
- While connected to the internet, open Google Maps and make sure you are signed in.
- Search for the city, town, or area you want to save.
- Tap the name or address that appears at the bottom of the screen.
- Look for More in the place details (on Android, you may need to swipe right to find it).
- Tap More, then select Download offline map, then confirm with Download.
That method downloads a pre-set area around a searched city or place. For more control, choose the custom option instead:
- Tap your profile picture or initial in the top corner of the app.
- Select Offline maps.
- Choose Select your own map.
- Drag and resize the highlighted box to cover the full route, including likely detours.
- Tap Download to save that custom area.
The custom option is usually the better choice for road trips, since it lets you stretch the boundary along an entire highway corridor instead of one city center.
📱 iPhone vs. Android Differences
The overall steps match closely between the two platforms, but a few details differ enough to cause confusion.
On iPhone or iPad, the starting point is the same search-and-tap flow, but Incognito mode blocks downloads entirely, so check that setting first if the download option seems missing.
On Android, the place sheet sometimes requires swiping right before More appears, which can make the option seem hidden if you only look at the first row of icons.
Android devices may also offer the choice to save maps to an SD card, though this depends on the specific phone model and is not guaranteed to be available.
| Step | iPhone / iPad | Android |
|---|---|---|
| Search and open place | Tap name/address at bottom | Tap name/address at bottom |
| Find More menu | Visible in place sheet | May need to swipe right |
| Custom area download | Profile icon → Offline maps → Select your own map | Profile icon → Offline maps → Select your own map |
| Storage option | Device storage only | SD card possible on some devices |
| Incognito mode | Downloads blocked | Downloads blocked |
Because menu labels and layout can shift with app updates, it is a good idea to use the search bar inside the app Settings or profile menu if a labeled option has moved from where these steps describe.
✅ Using Offline Maps On The Road
Once an area is downloaded, using it feels almost identical to normal online navigation.
Open Google Maps as usual and enter a destination. If the start and end points, along with the route between them, are fully inside the saved area, turn-by-turn driving directions should work normally.
GPS location tracking can still function without cell service, since it relies on satellite signal rather than a data connection. This means the blue location dot can keep moving along the map even in a dead zone.
It helps to start navigation while still connected, if possible, so the route calculates correctly before signal drops. Once the route is set, the app can continue guiding turn by turn through the offline area.
💡 Key point: Starting the route while still online, then losing signal partway through, tends to work more smoothly than trying to calculate a brand new route from a dead zone.
⚠️ What Offline Maps Cannot Do
Offline mode solves driving directions, but it does not turn Google Maps into a fully offline app.
Live traffic conditions are not available offline, so the app cannot warn about a backup ahead or suggest a faster alternate route around it.
Walking, cycling, and transit directions are not available in offline mode at all. Only offline driving directions are supported, according to Google’s own help documentation.
Downloading a map does not make every feature in the app work without a connection. Search results for new businesses, reviews, and real-time transit schedules all depend on an active internet connection.
⚠️ Watch out: A common mistake is assuming the whole app works offline once one area is downloaded. Only driving navigation inside that exact saved boundary is supported, nothing else.
🛠️ If Offline Navigation Is Not Working
When offline directions fail or will not start, a few checks usually explain why.
Confirm that the entire route, start to finish, sits inside the downloaded area. A route that exits the boundary even briefly can break offline navigation.
Check whether the saved map has expired. Google notes that offline maps can expire over time, and the app tries to refresh them automatically over Wi-Fi when they are within 15 days of expiring.
If an update is needed, go to the profile picture or initial, select Offline maps, choose the specific map, and tap Update.
If the download option never appeared in the first place, check the internet connection, confirm the app is up to date, and verify that offline maps are supported in that country or region, since availability is not universal everywhere.
- ✅ Confirm the full route is inside the saved boundary
- ✅ Check the map’s expiration status
- ✅ Update over Wi-Fi if it is close to expiring
- ✅ Verify app version and internet connection
- ✅ Confirm offline maps are supported in that region
📦 Managing Storage, Updates and Expired Maps
Offline maps take up space, and larger regions mean larger file sizes, so periodic cleanup can be worthwhile.
Inside the Offline maps section of the profile menu, each saved map is listed individually, which makes it possible to review, update, or remove maps no longer needed.
Because maps can expire, it is a good idea to open the app on Wi-Fi occasionally and let it refresh any area that is close to its expiration window, rather than discovering the gap mid-trip.
🙋 Frequently Asked Questions
Q. How much storage does an offline map use?
Storage size depends on how large an area is selected; a single city takes less space than a wide custom region covering an entire highway corridor, so leaving extra free storage before downloading is sensible.
Q. Can offline maps be used in another country?
Offline map downloads are not available in every country or region, so it is worth confirming availability for that specific location before relying on it for travel.
Q. Will offline maps drain the battery faster?
GPS tracking and an active navigation screen can use battery whether online or offline, so the offline status itself is not the main factor in battery drain.
Q. Can multiple areas be downloaded at once?
The Offline maps section lists saved maps individually, which allows more than one area to be stored, as long as device storage space allows it.
Q. Does offline mode work for walking directions?
No. Offline walking, cycling, and transit directions are not supported; only offline driving directions work within a downloaded area.
Q. What happens if the map expires mid-trip?
An expired map may stop providing reliable offline navigation, which is why checking and updating the map on Wi-Fi before departure helps avoid the issue entirely.
Q. Why does the download option sometimes not appear?
This can happen due to a weak internet connection, an outdated app version, Incognito mode being active on iPhone, or offline maps not being supported in that particular region.
📌 Quick Summary
