[CA] [CA11] Radio Navigation Interface Z075

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Joseph,

The older Autohelm 1000 with a 4 pin plug on the underside was pre SeaTalk and the only way to connect NMEA to it is via an interface box, part number Z075. This was called the Radio navigation interface, was 4" square and had a rotary knob on the front as well as a red and a green LED. Unfortunately, this autopilot design predates Raymarine. Unfortunately, support for this product has not existed for many, many years. Best wishes with your search.
