Got this one fixed! Sergey Kozlov, who sells firmware updates for these systems, (links to his facebook contact info are on other android threads in this forum) let me know that I had to set Settings...User Settings...Parking Sound to On. I was changing a similar sounding but different function in User Settings. Now the audio no longer shut off in reverse. I think I will try his firmware update for my system.(2) The audio always shuts off when I put in in reverse. These is a setting in Settings...General...User Settings to activate or disable this function but that setting makes no difference, it always shuts off in reverse. I wish it would stay on.
But he had no advice for my daytime dim dash and no video out on the back display port connector.
