I have looked for info on this problem and if anyone has posted an answer, I apologize. My problem is this. Bought new 34P Hurricane. Do not remember if radio was tested during walk thru, but now (3 weeks later) turned on the radio, blue tooth, etc. and speakers (2 up front, 2 under cabinets) will not work. I have tried restoring defaults, unmuting, equalizer, and no sound. I see a speaker icon on the screen and it is grey (as if off), and if I push mute, I see a blue speaker, but with an x beside it. I have checked fuses under the driver seat, but not sure which one is for radio, but none appear to be blown. Hate to take motorhome back to the dealer for this. Any ideas?
