Gx470 Levinson Cd Changer Problem

calistyle · September 19, 2007

I have recently purchased 2004 GX470 with the mark levinson audio system. When I push the "disk" button on the radio the display on the nav unit says:

"the external system is not connected". I have taken apart all the systems associated with the changer and radio and have found everything connected. Has this happened to anybody before? Please help.

if you have a rear seat entertainment screen a singlre dvd player should be in the back of the center console. if its missing it could be stopping the changer from showing. up . also if the changer is not working or if the avc lan wiring is not working screen will say the not connected. the 6 disc changer is mounted underneath the glovebox . the 2004 screens had a defect in the tx tm communication wires thAT ALSO COULD CAUSE THE PROBLEM.. a dealer could do a check for you to see what the problem lies. i have a 6 disc gx changer with the 32 pin plug if you would rather plug it iin and see if it cures the problem.

Thank you for the info. I took the vehicle to the not so local Lexus dealer and they told me that my "rear audio controller" was missing. You don't happen to have one of those do you?

This is the rear audio controller located in the headliner you speak of?

I will need one that works with the Levinson audio sysytem. Do you have a contact #?

there are 2 different gx470 rear systems and 2 diferent controllers. one has dvd screen flip down called rear entertainment system. . the other is a rear audio controller no video invloved. call me at 937 322 1760 to figure out which one you have. i dont understand why the dealer didnt give you the part nunmber and price of the part you needed but i will help you figure it out. very hard to do by club posts. i deal in this every day and cant figure out what you need without asking more questions. gx470 rear audio controller is actually in the back of the console along with ac contols for rear air. a lot of dealers have no idea of the different options in a gx470.

Calistyle, were you able to get this fixed? I have the same problem on my 2006 gx470?

I am having the same problem with my CD changer. I recently had an Invision G10 drop down DVD player installed in place of the headliner Rear Seat Audio System (no DVD) unit. It was done by a local car audio video specialty company here in Seattle. Ever since the install of that unit, I get the same message about the CD changer. If I read these posts correctly, it sounds like that overhead display unit is necessary for the CD changer to work. Hopefully, there is a bypass of some kind :rolleyes: If anyone has any experience with this problem, I would love to hear about it.

I plan to take the car to the dealer this Saturday (to have a faulty hinge on the glove box checked out). I was hoping a connector on the back of the CD changer had been pulled loose but it looks like it may be more complicated than that.

BlueLexus! PLEASE tell me you found a solution. I just got an overhead DVD put in at CC and am having the same problem. How do you fix this?
