Check your manual, on page 15 it shows the wiring
for the connection to a device to provide Lat and Lon info.
This could be your chartplotter
, if you have one, or a standalone GPS antenna
You should have a small wire harness on the back with grey, green, and blue wires. This is for the NMEA
data input and output from a GPS. It would be connected with radio out to antenna
in, radio in to antenna out, and grounds connected.
Pretty simple, you can do it.
Let me look for an antenna that will work
Here's a pdf for your manual if you don't have one. Link on the page just below the pic of the radio.
edit,..... well, choosing an antenna is a bit more difficult, for me. Of course the puck
style are cheaper but usually USB or serial
. With pinout info they could be adapted but that's more head
