I had a DVD entertainment system installed by Dr. DashBoard. Bottom line is that everything works great, except that the when you push the disc button...it says CD changer componet not connected? Its going to the Lexus dealer on Friday but, was curious if anyone has a suggestion or similiar problem? Oh...and its actually connected. The CD changer is factory but, DVD rear system was installed 4 days ago. I'm thinking they just have some wire connected interfering with the mode to go back to the CD changer for it to play? Thanks, M. Dillon
