Description
Simrad GN70 CDU Navigation System – IMO Compliant Control & Display Unit
Part Number: 000-10913-001 GN70
This control and display unit pairs perfectly with the GS70 GPS antenna (000-11137-001). It also works with a wide range of IMO type-approved GPS smart antennas. Additionally, It’s compatible with the HS80 GPS compass 000-10938-001, and MX575C DGPS compasses 000-10747-001, either straight over N2K, or through the MX610JB.
Built on NMEA 2000
The GN70 control unit runs on a NMEA 2000 (N2K) network. That means true plug-and-play. Connect it to the AP70/80 autopilot, Class B-AIS, or any other N2K-enabled navigation gear on your bridge.
One display. Total control. Adjust backlight settings across your entire Simrad N2K system, or switch heading sources — all from the GN70 screen.
