Hi there! I see you’re having trouble downloading offline maps in the Garmin Explore app on your Android device. Let’s make sure we get that sorted out for you. To better assist, could you tell me if you’re seeing any error messages when the download fails? Also, have you tried to download the maps over both Wi-Fi and mobile data?

In the meantime, here’s a step-by-step approach you can follow that often resolves offline map download issues in Garmin Explore:

1. Ensure you have enough storage space on your device. Offline maps require a good amount of storage, so check that your Android 10 device has enough free space.

2. Update the Garmin Explore app to the latest version from the Google Play Store. An outdated app can cause download problems.

3. Check your internet connection: Use a stable Wi-Fi connection if possible, as offline maps are usually large files.

4. Try downloading the maps again:
- Open Garmin Explore app.
- Go to “Offline Maps.”
- Tap “New Offline Map” and select the area you want to download.
- Follow prompts to initiate the download.

5. Clear app cache and data: Sometimes corrupted cache can block downloads.
- Go to Android Settings > Apps > Garmin Explore > Storage.
- Tap “Clear Cache” then “Clear Data” (note: clearing data may log you out).
- Relaunch the app and try downloading again.

6. Reinstall the app: If clearing cache/data doesn’t help, uninstall Garmin Explore and reinstall it. A fresh install often resolves hidden issues.

7. Toggle airplane mode briefly after download starts: There's a reported workaround where after starting the offline map download, switching airplane mode on and off resets connectivity and allows the download to complete properly.

If you’ve already tried any of these steps, please let me know which ones, and we can look into more specific fixes such as checking permissions or app settings.

Do these steps sound doable? I’m here to help guide you through any part of this!
