Map downloads require the app to remain in the foreground. For this reason, we suggest plugging your device in and leaving the download to run overnight for larger map selections.
If Auto-resume is turned off in the Gaia GPS settings and a download gets interrupted for any reason (like navigating away from the app), you'll see the option to "Resume Download" under "Show on Main Map" on the map details screen--this means your map download is incomplete.
Testing downloaded maps that do not offer an option to Resume Download:
- Disable Wifi and Activate airplane mode on your device to disable cell access (GPS still works in Airplane mode after iOS 8.4)
- Open the app > tap Settings > Storage > Clear Cache > select 'OK' when the pop-up Warning appears.
- Then open your map download on the Main Map by tapping Saved > select Maps from the Saved filter > tap the name of your downloaded map > tap the more (...) icon > tap Show on Main Map.
Your downloaded tiles will show clearly and the surrounding area will be blank or blurry.
