You mean no sound, no lights, no action? Or just no sound in the drivers area. If you have nothing, sounds like a fuze blown. If so that's a simple solution, go to you fuze panel and check for open fuze.

I have the 2017 ACE 29.3 I would check the fuse for the radio. Thats of course if you have nothing on the screen. If you have something else working i.e. the camera then its all on the touch screen. I think alittle more info on your part would help.
