By the way, what is the reason why the mobile phone can't connect to the highland?

If you can't find mobile navigation, we suggest you try the following methods:

1. Turn it off and then on.

2. Settings-(More/General)-Location Service (Location)-On (Use GPS Satellite-Check).

3. If the mobile phone supports the A-GPS function, it is recommended to turn it on. Mode: Settings-(More/General)-Location Service (Location)-On (Using Wireless Network-Check)-(If A-GPS is turned on, it will consume traffic).

Try to search for more than three satellites when the weather is clear. If the satellite can't be searched, it may be related to the weather, location and buildings at that time.

5. Try changing to another location.

6. If you still can't search for satellite positioning, it is recommended to try downloading navigation map data again.
