Re: Chartplotter repeater
There are a couple ways to do it, depending on which garmin you have.
With the models above the 740 you can network them easy peasy. With the others you would have to connect them via NMEA 0183 or 2000. 2000 is much easier to wire IMO.
you can also transfer waypoints and routs via the SD Card reader as well.
