I just bought two sonar/gps units and am preparing to install them as a network, sharing an antenna.

I have a power switch on the dash that currently controls power to the existing fishfinders and CD player.

The installation instructions show two separate switches (one mandatory for the network cable because the GPS antenna is always on) and another listed as "recommeded" for the display unit.

I'd like to terminate all three power leads (two displays and one NMEA 2000) at the same switch, being sure to install the three separate 3 amp fuses included w/ the units on each power line.

Any problems with this arrangement?

Thanks,

John
