If your DataHub GPS status is VOID, yet all the information populates, it may be confusing why it isn't working correctly and won't update your tracking position.
The reason is that the GPS date is old; the above example shows 2004. This indicates the GPS is stuck in the last epoch time and needs 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 try again.
