  If the touchscreen on your Raymarine Marine Equipment does not operate as expected, ensure that the touch lock is disabled. The touch lock can be turned off on the home screen using the Joystick. Also, make sure you are operating the screen with bare fingers, as gloves may prevent correct operation. Calibrate the touchscreen using the setup menus. If there are saltwater deposits on the screen, carefully clean and dry the screen according to the provided instructions.

Why is instrument data missing from all Raymarine a77 Marine Equipment displays?
- J
  Jesus EdwardsAug 31, 2025
  If instrument, engine, or other system data is unavailable at all displays on your Raymarine Marine Equipment, check the data bus (e.g., SeaTalkng) wiring and connections to ensure data is being received at the display. Verify the overall integrity of the data bus (e.g., SeaTalkng) wiring. Check the source of the missing data (e.g., ST70 instrument or engine interface) to ensure it is operating. Also, check the power to the SeaTalk bus. If a software mismatch between equipment is suspected, contact Raymarine technical support.

  If there is no waypoint/routes synchronization with the Navionics Marine app on your Raymarine Marine Equipment, the smartphone/tablet may not have the “Navionics Marine” app installed and running. Download the “Navionics Marine” app from the relevant app store and start the app on the device.

What to do if Raymarine Marine GPS System won't boot up?
- J
  Jaime MaldonadoSep 23, 2025
  If your Raymarine Marine GPS System product will not boot up or is in a re-boot loop, first refer to the solutions for 'Product does not turn on or keeps turning off'. If the issue persists, it could be due to software corruption. Try re-flashing the latest software from the Raymarine website. As a last resort, on display products, you can try to perform a ‘Power on Reset’; however, this will delete all settings/presets and user data (such as waypoints and tracks) and revert the unit back to factory defaults.

What does it mean if my Raymarine Monitor displays 'No Data' or 'No scanner message'?
- J
  Jennifer MartinezAug 28, 2025
  If your Raymarine Monitor displays 'No Data' or 'No scanner message', check the scanner power supply cable to ensure it's sound and connections are tight and free from corrosion. Also, check that the scanner is correctly connected to a Raymarine network switch or SeaTalkhs crossover coupler, as applicable. Ensure the scanner pedestal switch is in the ON position.

  Tyler FoxAug 27, 2025
  If your Raymarine Monitor will not boot up, it could be due to the power supply and connection issues. Also, in the unlikely event that the product's software has become corrupted, please try re-flashing the latest software from the Raymarine website. On display products, as a last resort, you can try to perform a ‘Power on Reset’; however, this will delete all settings/presets and user data and revert the unit back to factory defaults.

What to do if my Raymarine Monitor displays a “No Fix” GPS status icon?
- D
  Deanna BurkeAug 27, 2025
  If your Raymarine Monitor displays a 'No Fix' GPS status icon, it could be due to your geographic location or prevailing conditions preventing a satellite fix (check periodically in better conditions or another location), a GPS connection fault (ensure external GPS connections and cabling are correct), or an external GPS antenna in a poor position (ensure the GPS antenna has a clear view of the sky).

Why does my Raymarine Monitor not turn on or keep turning off?
- C
  Carl NormanAug 26, 2025
  Your Raymarine Monitor might not be turning on or keeps turning off due to several reasons: a blown fuse or tripped breaker (check and replace if necessary, and inspect for cable damage if fuses repeatedly blow), a poor or damaged power supply cable or connections (ensure the cable is fully inserted and locked, check for damage or corrosion, and flex the cable to check for reboots), incorrect power connection (ensure the installation instructions have been followed), or an insufficient power source (check the power supply voltage under load).
