Ethernet

I didnt know you could use both? So I could theoretically get a lakemaster for use on bow unit but keep the navionics for the console?
Would I still be able to share waypoints between units as long as ethernet connects them?

For sure you could do that .... also, the waypoints are not saved on the map card. They are saved to the unit's memory and the waypoint is then overlay-ed on the map image.

You can share the waypoints between units via Ethernet regardless of what map card is used.

Many thanks BobB......your a wealth of information. I appreciate it
