2015 SX Turbo 23000 miles. All of a sudden the other day I stopped getting any kind of sound from the head unit. No music, no navigation, no bluetooth. I can still see what is playing,switch stations, my navigation works but with no voice. I have checked the fuses. I have factory reset the head unit, disconnected the negative side of my battery for 45 minutes and now I disconnected the negative and positive on my battery. Has anybody had this type of problem before?
