How can I update the firmware to fix the screen problem

1. Connect your device to a Wi-Fi network. If you don't have access to Wi-Fi, you can use your smartphone's hotspot feature[4].

2. On your Garmin DriveSmart 65, tap the "Settings" icon[3].

3. Tap "Updates" in the settings menu[3].

4. Select "Settings" again, then choose your preferred Wi-Fi network if not already connected[3].

5. The device will check for available updates. If updates are found, select "Install All"[4].

6. Accept any agreements that appear[4].

7. Allow the device to download and install the updates. This process may take some time, depending on the size of the update and your internet speed[4].

8. Once the update is complete, the device will restart automatically[4].

9. After restarting, you may need to go through the initial setup process again, such as selecting language and region[4].

It's important to ensure that your device is fully charged or connected to a power source during the update process to prevent any interruptions that could cause further issues[1]. If the screen problem persists after updating the firmware, you may need to contact Garmin support for further assistance, as it could indicate a hardware issue requiring professional attention.
