Wiring a 585L to a Garmin 3010?

[Sea-r-cy]

Is it possible to wire a Furuno 585L to a Garmin 3010? If so, what is the wire color to wire color on each, and do I need to change any of the settings in either unit? Thanks!!

It depends on what your trying to accomplish.

Are you trying to get TLL to work? (Because Garmin units don't accept NMEA TLL) Are you wanting to send GPS to the sounder or Depth/Temp to the Garmin (or both)?

Is the Garman 3010 NMEA 0183 at an RS232 or RS422 signal level?
