Models below and newer have NMEA 2K:After doing research, I dont think I can hookup my honda to a nmea 2000 network. It's a 2003. I'm checking the serial number tomorrow.
I heard that Honda didn't do it til 2010.
You may also need a NMEA 0183 connection from your GO fish finder to the DSC connection on your radio unless your radio has a NMEA 2K connection or an internal GPS antenna. They are different NMEA systems.
