I am just in the stage of wiring and installing my avionics and curious about dimming. I will have 2 5600's and 1 5500 screens and was curious if you need to dim all screens independantly or when one is done the others follow?

Second question is, is there a way to hook up other items like the GTN-650 or GMA 240 also so they all dim together.

Thanks for help.
