There is no priorization on the GPS source other than enabling/disabling the modem GPS.

If a vehicle wants to support both car and modem, it shall check config modem/enable.gps (and modem/enable.gpstime) and suppress the car data while the modem is

The vehicle can also require and release the modem GPS dynamically by sending the events

  * vehicle.require.gps
  * vehicle.require.gpstime
  * vehicle.release.gps
  * vehicle.release.gpstime
