On the Enform how to I keep the audio screen displayed. When I am listening to the audio the screen keeps returning to the Map Screen.

Also how do I change quickly from radio to cd to hd radio without having to click all those tabs?

Ideally whatever screen I have on that is what I want to stay on.

 

Check the manual if it's possible. With respect to the tabs and pushing the buttons, try using the stereo mounted controls.
