Radio making loud crackling noise then there’s no sound and cannot change channels.
Try resetting the stereo by removing all related fuses. If this doesn’t work, you likely need a new radio. You may be able to find a used exact replacement, but you would probably be better off with an aftermarket unit. Note: the aftermarket route is not recommended if you have the 8" LCD screen stereo system. Go to Crutchfield.com for details and advice.
