1. Confirm file status: Verify the target area map has been downloaded and the file status shows as "In Use."
2. Check scale levels: The map displays the full road network at scale levels 50 m-200 m. Levels 500 m-20 km+ show only major roads. Adjust the scale to view.
3. Restart the device: If the map display remains abnormal, try restarting the device and check again.
4. Redownload: If the above methods fail, delete the map file and download it again.
