  If your Furuno Compass isn't showing a position fix, start by checking that the antenna cable is firmly connected. Also, ensure there are no obstructions blocking the antenna's view of the sky, which could prevent it from seeing enough satellites. You may also try restarting the GPS by going to the main menu, selecting [SYSTEM]o[RESET SETTINGS]o[CLEAR GNSS]o[YES].

Why Furuno Compass heading indication changes randomly?
- T
  thornAug 13, 2025
  If the heading indication on your Furuno Compass changes randomly while anchored, or doesn't change when moving, it could be due to a poorly located antenna or the antenna being unable to obtain a positioning fix. Consider the following: 1) Ensure the antenna has a clear view of the sky. 2) Verify the installation location isn't subject to excessive vibrations. 3) Confirm the antenna isn't experiencing interference from nearby equipment. It may also be due to a faulty sensor. Check the sensor status from the [SENSOR] menu and run a [DIAGNOSTIC TEST] from the [MAINTENANCE] menu. If one or more sensors are faulty, contact your dealer for advice.

What to do if data output from Furuno Compass SC-70/SC-130 does not appear on external equipment?
- D
  David LawrenceNov 8, 2025
  If data from your Furuno Compass SC-70/SC-130 isn't showing up on external equipment, first check the connection between the SC-70/SC-130 and the external equipment; replace or reconnect/refasten as necessary. Next, verify the output settings by navigating to [I/O] in the main menu and selecting the output port to confirm the settings are correct. The sensor may also be faulty. Check the sensor status from the [SENSOR] menu and run a [DIAGNOSTIC TEST] from the [MAINTENANCE] menu. If one or more sensors are faulty, contact your dealer for advice. Finally, make sure the external equipment is set correctly. Check the external equipment data input settings and ensure that the output data and input data connection should set as follows: SC70/SC-130=TD-A connection to external equipment=RD-A SC7...
