If your DataHub on the NMEA GPS status page shows VOID, yet all the information populates, it may be confusing why it isn't working correctly and won't update your tracking position.

Take a look at the Date, Does the GPS date appear old?

The above example shows 2004. This indicates a GPS device connected to the NMEA 2000 network providing the GPS feed is stuck in the last epoch time and the GPS device providing the GPS feed requires a Firmware update.

You may have multiple GPS sources connected to the boat, so you must carefully check each one to see which needs the update.

Please do this and then check this NMEA GPS status page again.
