 GMI 10 Quick Start Manual
Using the GMI 10
Use the GMI 10 to view numerical
data provided by connected
sensors. Many data types can also
be displayed as an analog gauge
( page 6 ).
The types of data available
are determined by the sensors
connected to the GMI 10 either
through NMEA 2000 or NMEA
0183.
For example, when connected
to a GPS antenna such as a
GPS 17x, the GMI 10 can show
GPS position, course over ground,
speed over ground, average speed,
maximum speed obtained, and
distance traveled (trip odometer)
information.
Viewing Information
Instrument screens are organized by
category. The categories available
are:
Surface—speed, heading, odometer
(requires a GPS antenna or other
sensor that measures speed or
heading).
Water—depth and temperature
(requires a sonar device such as an
intelligent transducer).
Fuel—level, rate, range, economy
(requires a fuel sensor such as the
GFS 10). You must also have a
sensor that provides speed to use
range and economy information.
