Im wanting to input my own RGsB signal, which Im ok doing - thinking ahead im wondering how I stop the boardmonitor thinking its still talking to the nav drive - ie i want to still be able to use the rotary knobs to control my pc program and not to still send them to the nav drive...

The way I would be doing it would mean all im doing is stopping the nav drive signal getting to the screen, so if i still used the knob things would still be doing all sorts of things in the background.....

do I either disconnect the ibus from the nav drive
or is there some mode i can put the board monitor into
or does using the reverse camera enable pin stop the interaction with the nav drive?

any thoughts?
