Full Version: [CA11] NAV398 GPS/LORAN Sensor Replacement
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
Our 1999 SeaRay 310 Sundancer has a Raytheon NAV398 GPS/LORAN with an external sensor mounted on the radar arch. The protective cowling on the sensor completely disintegrated when I removed the shrink wrap this spring. Is there a GPS sensor available that is compatible with this display head?

Alternatively, is there a newer display head and sensor combo that would fit existing cutouts with little modification?

Thank you.
Welcome to the Raymarine Forum MissHan,

Please click here to view a thread within Raymarine's old Forum in which I had previously addressed this subject. Unfortunately, Raymarine, Inc. does not offer a GPS sensor with may be substituted for your failed sensor.

Raymarine does not offer a GPS/chartplotting product which is specifically designed to be installed within the cutout/footprint of the NAV398. However, I believe that you will find that Raymarine's Axiom 7 MFD is quite close. Please click here to view a FAQ addressing installation locations which do not afford MFD's having internal GPS receivers an unobstructed view of the skies overhead.
