10.6 NMEA DISPLAY PAGE
The chartplotter 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.

10.7 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 chartplotter. This page can also be used to see
if the GPS chartplotter NMEA output is being loaded down by a external NMEA device the
GPS chartplotter 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 chartplotter is transmitting the sentences:
1. Press [MENU] and highlight
NMEA DISPLAY with the ShuttlePoint knob.
2. Press [ENTER] or move the ShuttlePoint knob to the right.
3. Move the shuttlepoint to highlight
DATA.
4. Press [ENTER] or move the ShuttlePoint knob to the right.
5. Connect the BLUE Wire on the GPS chartplotter to the junction of the Brown wire and
the VHF wire. The display should look similar to the picture below.
