I have a '03 EX-L. It has the front/rear DVD sound system. The issue is on the display it shows that the radio is on, the volume goes up and down, it switches to CD/DVD, AUX, and AM/FM. However no sound comes out of any of the speakers in any of the modes. The DVD displays on the overhead screen but no sound. Also, the volume/audio control on the steering wheel does not work either. Any thoughts? Thank you.
