Hello all i just purchased a 2006 Eddie Bauer Edition Expedition and cannot figure out for the life of me this darn stereo. I have the 6 disc changer with the overhead dvd player in the back no sat or nav. My question is the only way i can get the sound to work from the dvd player over the speakers is via the FM Modulator built into the dvd player. From what ive read the Aux button on the radio is supposed to work it but when ever i push it it says No Aux Audio. The wireless headphone work fine. Or is the Aux button for something different. Alternatively I plugged in my iphone into the left and right rca connector on the back of the roof dvd and still had the sam message no ax audio. Please help me
