The GN70 is a versatile global navigation system that offers a NMEA 2000 (N2K) interface for easy plug-and-play connection to high performance modules such as the AP70/80, Class B-AIS, and other navigation systems that are N2K enabled. The GN70 can be used as a single display, or multi-unit redundant displays. The NMEA 2000 interface means the user can change things like backlight settings across all Simrad NMEA 2000 capable electronics on the bridge, or switch to a different heading source all from the GN70 display.
GPS Antenna Options
The GN70 is a type-approved navigation system with the MX521A or MX525A/MX5B D/GPS antenna (via the MX610JB –NMEA 2000 to NMEA 0183). The GN70 is also compatible with the HS80 and MX575C DGPS compasses (via a N2K connection or through the MX610JB).
