Upon entering the Ford f150 vehicle and turning it on there was loud sonic boom noise through the speakers and then ear piercing static. It could not be turned down by the radio controls. Radio was turned off but static still wouldnât stop. Vehicle was turned off and static still was still going. I waited 15 minutes with the vehicle off and it finally quit. Truck started no problem and static gone. I have read of numerous reports about this same thing with the B&O Unleashed radio system which I have. I have suffered some hearing loss and ringing in my ears even after 2 days. If this had happened on the highway or in traffic it would probably have caused a wreck.
