If the "Navigate" LED of the BikerSOS GPS tracker lights permanently, this means that the tracker currently has no GPS connection.
This also means that no location can be determined. But don't worry, after installation, the BikerSOS GPS tracker normally finds the signal after a few minutes and can then hold it.
The fact that the tracker does not receive a GPS signal can have various causes such as the vehicle in which the tracker is installed is in an underground parking garage or basement. The tracker is working correctly, only the GPS signal is missing, as it is sometimes the case with mobile phones when they are inside buildings.
