Function and Audio buttons suddenly do not work, any ideas? Replaced the face console that covers the radio and heater controls, perhaps something got jiggled? Wiring was inspected and looks fine. Radio/CD works although fades out on ATT while listening to music, and I never paired my phone to it - so not sure why this happens either. Would like to totally deactivate that as well, but for now really need function button to scan so I can change controls. Will only display BSM/Local but won't scroll to any other functions. Thanks!
