Update GPS II while plugged into Royal or Mercury

  • After updating my Royal to 23.09 I wanted to update my GPSII. While connected to the Royal via PC-Control I selected GPS II in Terminal.

    I went to update GPSII from online but got message that the version or firmware was corrupted.

    There was a recovery option but I stopped because I didn’t know if I could update GPS II from terminal if GPSII was plugged in to Royal via Terminal or if I have to remove GPSII from Royal and update as separate unit.

    Please advise
