I have 17k miles on the truck and suddenly no sound. My Link display still works, bluetooth still dials by voice, but can't hear the person I am talking with. No sound out of the speakers. The turn signals don't make a sound, the radio doesn't play, my iPhone doesn't play, the reverse assist doesn't make a sound, no sound for seatbelts. Nothing. The display shows I am listening to which ever source I choose, but nothing. Anyone else have these issues? I'm new here and quickly searched the threads, but didn't see anything. Thanks for any and all advice!
