Just purchased this truck 4 days ago and went to play a dvd and getting no sound through speakers, it did not come with the wireless head sets or remote. the truck has the bose system from factory. The dash indicates a headset icon on the radio. the rear controls on the console will switch to am fm and cd but not dvd. does anyone know how to switch the icon on the face of the dash mounted radio. i've looked up the owners manual online did everything it stated then some. sound works with am/fm/cd and also works with wired headset. but no sound for dvd player. Ive read most of the threads on here about how to fix it but havent seen anyone with this exact issue. (headset Icon). just want to know if its operator error or something wrong with system. Thanks for taking the time to read and or help =)
