I figured out my problem. The audio cables running to the rear radio (white and red) were not plugged into the radio they were just laying there. Plugged them in to the jacks that were hanging and hit aux 2 on radio and there it was. Thanks to this forum I have fixed a lot of stuff on my 2018 Ace 30.3. Its scary some of the stuff that was not checked at the factory and the dealership. It seems that everyone has the same issues. My outside speaker by the door was also never hooked up from the factory.
