Hi, I just bought a 2007 Grand Voyager Executive which has the 6 CD autochanger, SatNav and DVD. Everything works, insofar as the radio and SatNav displays are fine and the DVD works but the audio from any of the units is intermittent. It usually comes on when I turn on the ignition but then goes off again soon after, but sometimes it comes on and stays on until I turn off the ignition. Apart from that ****le and the fact that the car didn't come with any headphones, I love it. Has anybody else experienced this problem and does anybody have a solution?
