I don’t receive any GPS signal on my phone, what can I do?
Make sure that your device is equipped with an internal GPS Sensor. If this is not the case, an external GPS sensor is needed. Also check that you have allowed Air Navigation Pro access to the device location services. In iOS, go to iOS Settings, and select Air Navigation Pro from the menu, then set location to “Always”. On Android, go to Settings > Apps > Air Navigation Pro > Permissions > Location. Check in Air Navigation Pro that the app is using the internal or external sensor as source for the location. This can be done by going in the app to Tools > Sensors.
