I have the D10A and EMS-D10 in my -9A. No problems reading them and great bang for the buck as I purchased them used from aviators with more "experienced" eyes that wanted bigger screens.
Good sunlight readability and information display, imho.
Sam - I have audio on my AOA - I know you well enough that I am missing something in your question - I just had to hook the audio wire up to my aux audio input - If it was only that, you would have done it already.
