E120 Classic GPS

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum bocaboat,

As the E-Series Classic MFD does not feature an internal GPS receiver, it cannot be directly interfaced to a passive GPS antenna (they have a coaxial cable). Unfortunately, unless the GPS antenna was of Raymarine origin, we may not be able to identify it. It is recommended that the antenna, including its underside, be inspected for markings which may identify its manufacturer, product name, or part number. If powered and properly interfaced, it may have simply failed. In the case of the latter, it would be recommended that it be replaced with a Raystar 150 GPS Sensor.
