When connecting the External Speaker, Chart Plotter, or External GPS An-
tenna, strip off about 1 inch (2.5 cm) of the specified wire’s insulation, then
splice the ends together.
CAUTION
Care must be taken not to touch any of the NMEA wires (blue, gray
or brown) to positive 12 VDC or the radio may be damaged.
External GPS Connections (4800 baud)
When the GPS reception is limited, such as the flush mounting of the
GX1700
, the NMEA input (+) (Blue) and NMEA input (-) (Green) wires may
be connected to the NMEA output connections of a external GPS antenna
or GPS Chart Plotter. To change the
GX1700
from using the internal GPS
antenna to the external GPS antenna, refer to section “
14.9 GPS SELEC-
TION
” (for selection), and “
14.1 UNIT POWER
” (for turn off).
NMEA INPUT (GPS Information)
• The GPS must have the NMEA Output turned on and set to 4800 Baud
in the setup menu. If there is a selection for parity select none.
• For further information on interfacing /setting up your GPS. Please con-
tact the manufacturer of the GPS receiver.
