To connect a chart plotter, connect the wires between the CD-38 and the GPS
and chart plotter. Insure that the wires are properly shielded from water.
When mounting the HX851 inside of a cabin where GPS reception is
limited, the NMEA input (brown) wire may be connected to a GPS Chart
Plotter to input position into the HX851. To change the HX851 from
using the internal GPS antenna to an external GPS chart plotter with
NMEA. Refer to section "10.8 POS DATA PRIORITY".
The Water Hazard LED must be turned off so the radio will output NMEA
data to an external device (VHF Radio, PC, etc.). Refer to section "8.12
LED SETUP".
