you are old school, you do not need them
Funny, your right,,,, but this question is for my son. I don't use graphs
Elite 7 Hdi on bow
Elite 7 Hdi w/ Chirp on console.
Linked via Nema 2000 interlink wire
Navionics map chip in console unit
Now unit will not display the map chart
Nor will it show waypoints from the console on the bow unit
How do we get them to communicate with each other ?
