What to do if Simrad MX512 Car Navigation system won't track satellites?

  terrymcintoshAug 4, 2025
  If your Simrad Car Navigation system isn't updating its position and the red traffic light is blinking for more than 10 minutes, the issue might be due to jamming from nearby transmitters. Try relocating the GPS antenna. It could also be a faulty antenna or cable, in which case you should replace the antenna. As an alternative, connect the MX421 power directly to the external 12 VDC supply. If the issue persists, the unit may need repair.

Why is there no data output to peripheral equipment from my Simrad Car Navigation system?
- T
  Tyrone StoneAug 8, 2025
  There can be several reasons why your Simrad Car Navigation system is not outputting data to peripheral equipment: * The NMEA output data may not be configured correctly. * The NMEA version might be wrong. * The output rate or format could be incorrect. * There might be an issue with the electrical standard. * Too many data sentences might be turned on, causing throughput overflow. * There might be more than one NMEA talker on the circuit. * The port could be faulty. * The MX420 requires the user to enable NMEA. If none of these are the cause, the unit may need repair.

  If your Simrad Car Navigation system shows a black LCD display and no traffic light, you should check the supply voltage, verify that there is no reverse polarity, inspect the wire installation, and check if the external fuse is blown.

What to do if Simrad MX512 is tracking satellites but not updating position?
- M
  Megan HoffmanAug 17, 2025
  If your Simrad Car Navigation system is tracking satellites but not updating its position (red traffic light is solid), it could be because the DGPS mode is set to DGPS Only and no corrections are being received. Check the maximum cable length restrictions and cable conditions, especially if the satellite signal is weak. It could also be caused by weak GPS satellite signals. If the satellite signals are weak, return the unit for repair.
