THE RESULTS ARE IN!!!! Thank you so much!!! I just installed the replacement ACM and it works FLAWLWESSLY!!! I'VE GOT SOUND!!! I can hear the calls and all of the voice activated prompts are functioning properly! Replacement part cost $89 and I didn't charge myself any labor. LOL! I'm VERY PLEASED!!! This forum SAVES MONEY, TIME, and UNNECESSARY AGGRAVATION!!! Thanks again Peterk9 and jmr061 for your insight!
