Hello everyone, I have just bought a second hand 2007 Grand Voyager. Love the vehicle got a couple of snags which can be fixed. However a problem I have is that I am not getting any sound from the CD/DVD/NAV RB3 system. Sometimes it will work really well (and sounds fabulous) then suddenly it will just go off and I can not get any sound at all. Would anyone have any ideas? I have checked not Muted. Hoping for a simple fix ie loose connection. Would welcome any advice. Thank you. Andy
