About a month ago I was getting ready for a trip to atlanta and the radio wouldn't work in the 4r. I noticed the volume wouldn't work on the dash or the steering wheel but would change modes or stations fine. Well tonight it did it again same deal no volume until you turn the vehicle off and back on again then its fine. Anyone experience this??? Also my wife was riding in the back seat passenger side with our newborn and said it smelled like something burning. Hot exhaust???Anybody have any ideas what this could be? Please only adults here unlike my last post where toyota loyalist jumped me for having issues with a 4r.
