dynon 10A
I have had the 10A in my 4 for about a year and love it. It was just the basic with no add-ons and with out the bright screen option and I can see it great (even without my reading glasses!) I just ordered the remote compass and AOA for it, the compass in my set up seems to only work when heading east. and the AOA just seemed to be a fun tool to have. - Ben
