Cab noise and radio reception
I have a 2010 Solera and was baffled by the cab noise until I discovered that there is a speaker for the rear camera mounted in the rear view mirror. It was picking up wind noise as I drove the mh. Once I turned down the volume on the mirror, the noise stopped. Problem solved. Hope that helps you. I too am unable to get any AM radio reception and not much FM either. Where is the antenna located? I've thought about taking it to an auto stereo shop, but hate to replace a factory unit.
