I have a 2004 GMC sierra 2500 with the BOSE system in it. I have my Ipod hooked up through the AUX. I hooked it up over a year ago and its worked fine. But now I cant get my radio to switch to the AUX using the steering wheel controls or the button on the radio. I don't have the XM but my ipod plays through the XM setting but the XM preview plays over the top of it. can anyone help? Its always played on the XM and the AUX setting.
