Audio DVD was inserted by mistake into the navigation slot. The MENU button does not function; I believe because it needs correct navigation DVD in the system to function. As a result I can't get the Map DVD screen to access the DVD eject switch. How can I eject the audio DVD from the navigation slot?[/quote]
Hi Josef, I struggled with this several months ago. The secret is there are hidden buttons on the LCD screen, in the top left and bottom left corners. Press the top left corner of the lcd screen (nothing will happen), then press the bottom left corner of the LCD screen (nothing will happen), press the top left corner of the LCD screen again; hey presto the DVD will spit out the disc!!!
I know its hard to believe but it works every time.

Let me now how you get on.

Thanks for this super solution. You know better then Lexus field technical specialists. Below I quote their email. Sorry I did not find your answer until today. I contacted Lexus customer service and was told to take it to a dealer. Then I contacted 2 dealership in California and was told the navigation drive must be removed from the vehicle and send to Denso. I contacted total 3 Lexus dealerships with the same result.
This is exactly what Lexus emailed me: "Matt Hollander forwarded your e-mail to the service department regarding your Navagation player/unit lacking ability to eject the non-Navagation DVD Disc. We contacted the factory field technical specialist, he mentioned that unfortunately, there is nothing on the car that will “sync” or prompt the eject icon to function. That is written into the Navagation disc. The only suggestion they made was to possibly have a close “Toyota” facility to remove unit, and perhaps either send to Denso for dismantling & retrieval of foreign disc, or attempt to remove outer case of player, & manually turn the feed rollers to eject dvd from player."
