When connecting the external speaker or GPS navigation receiver, strip off
about 1 inch (2.5 cm) of the specified wire’s insulation, then splice the ends
together using proper waterproofing techniques.
• 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 contact
the manufacturer of the GPS receiver.
• GX1150 can read NMEA-0183 version 2.0 or higher.
• The NMEA supported sentences are:
Input: GLL, GGA, RMC and GNS (RMC sentence is recommended)
Output: DSC and DSE
9.5 CHECKING GPS CONNECTIONS
After connections have been made between the
GX1150 and the GPS, a small satellite icon will ap-
pear on the top right corner of the display, and dis-
plays your current location (Latitude/Longitude) on the
display.
NOTE
• If there is a problem with the NMEA input from a GPS, the satellite
icon will blink continuously until the connection is corrected.
• If a GPS with NMEA output is not connected to the radio, the GX1150
will beep 10 minutes after the radio is turned on. After that the GX1150
will beep every 4 hours alerting to connect a GPS.
