FC-6000: Internal GNSS no longer working

If the internal u-Blox NEO M8 series GNSS receiver is no longer working in an FC-6000 or FC-5000 unit, some possible solutions are as follows.

Disable, then enable drivers

Tap and hold (right-click) on the bottom left Start button, and then select Device Manager.

Tap on Sensors > u-Blox GNSS Location Sensor, then select Disable device, and then tap Yes when asked.


When asked if you truly want to disable it, tap Yes.

  • Once it has been disabled, repeat steps to enable the device.
  • If needed, follow the same steps with Device Manager > Ports (COM &LPT) > u-Blox Virtual COM Port.
  • Once both drivers are enabled again with no warnings, verify the GPS function.

Note: Drivers for the internal GNSS (GPS) receiver in the controller install automatically through Windows Update.

Hard reset

Drain all power from the internal receiver to reset it. Follow these steps:

  1. Close running apps, then tap on Start > Power > Shut Down. Wait until both the screen as well as the red LED turn off (which can take a minute or two).
  2. Press and continue to hold the hardware Power button for 20 seconds (even as the red LED starts flashing rapidly at 10 seconds then stops at 17 seconds).
  3. Attach external power supply.
  4. Briefly press the Power button again, then wait for the unit to complete booting back up.
  5. Test the GPS function.
