Hi folks, I have a 2003 Roadtrek Popular 190. Does anyone know how to turn off the rear speakers? The owners manual says to press audio then scroll to fad (fade). When I press audio my options are bal (balance), bas (bass), or tre (treble). There is no fad. I called Roadtrek in Canada and the gentleman could not find an answer. He told me to call Chevy. They tell me to call
Any ideas? Thanks in advance!
