The WAAS/GPS Icon area may change due to the satellite reception:
ACQUIRING : the GPS is trying to receive a valid position fix.
GPS2D : The GPS is receiving at least 2 valid Satellites
GPS3D : the GPS is receiving at least 3 Satellites.
WAAS 2D/3D : the GPS is receiving a 2D or 3D position and the correction from the WAAS Satellite.
HDOP : Horizontal Dilution of Precision
VDOP : Vertical Dilution of Precision
12.5 NMEA DISPLAY PAGE
The GPS Chart Plotter is capable of displaying information in the customizable data
windows from external NMEA devices. Depth sounder, Speed Log with temp, Wind speed
and direction, Flux gate compass, and GPS information can be shown in any of the boxes.
The default NMEA Display shows 3 windows. When going to a destination, this screen is
useful to navigate as to get to the destination keep the Course Over Ground (COG) and
Bearing (BRG) figures the same.

12.6 NMEA DATA PAGE
The NMEA Data Page is very useful to see if a External device (example: Depth Sounder)
is transmitting NMEA sentences to the GPS Chart Plotter. This page can also be used to
see if the GPS Chart Plotter NMEA output is being loaded down by a external NMEA device
the GPS Chart Plotter is connected to.
Scenario: VHF Radio connected but the Radio is not receiving a GPS Position.
Usually the VHF Radio will be connected to the Green and Brown wires. To check to see
if the GPS Chart Plotter is transmitting the sentences:
1. Press [MENU]. Move the ShuttlePoint knob to highlight NMEA DISPLAY and press
[ENT].
