Here is one way to install chart plotter to DF1000 Whitlock steering system. I have made this for Lowrance 7500C, but it should be easy to install any chart plotter there. There is no room for bigger plotter than Lowrance 7500C.

Mika;
I have mine mounted on a swing-out arm, located inside the main cabin at the companion way. It can be used at the "nav" table or in the cockpit.
I have a Simrad unit that ties into all my other electronics, pretty neat what you can get today.
They did however say in the mounting directions not to mount it near a compass.
You may want to double check your mounting directions.
