Got this from the internet for 2005 LS430.
Not sure if it works!
Preparation
1. Set the hand brake, remove the key from the ignition switch, and open the hood.
2. Disconnect the negative battery lead from the battery terminal using the adjustable wrench. This will prevent any possibility of shock or shorting during the project.
3. Remove everything from the trunk including any protective mats lining the bottom of the trunk and leave the trunk open.
Resetting the Navigation System
1. Lift up the panel in the trunk that covers your spare tire.
2. Locate a square metallic box on the right side of the trunk. Use the screwdriver to remove the two screws holding the box in place.
3. Unplug the all of the wires connected to the box. Remembering where each wire is connected to the box is unimportant. Each of the wires is designed to plug into only one slot. Remove the box from the back of the car once all the wires are disconnected.
4. Unscrew the eight screws that hold the boxes rear panel in place to reveal two electronics boards.
5. Disconnect the left electronics board and flip it over so you can see where the two ribbon cables connect.
6. Disengage the two brown colored clamps that hold the ribbon wire in place on either side of the electronics board using your fingers. Disconnect the ribbon wires. Let the apparatus sit disconnected for one minute while the the computer resets.
7. Reassemble the navigation system following the steps given in reverse order.
8. Turn on the vehicle and test to make sure the system is working properly. Follow the directions on the screen.

Did any buddy ever figure this out it’s really frustrating I did the same thing it’s been several years so I’m hoping maybe somebody figured out how to fix it because the dealer wasn’t really helpful

I was messing around in the override menu and accidentally hit a program in the program list. Now there is Japanese writing and a caution error wrong disc screen that wont go away. I tried disconnecting the nav unit and disconnecting the battery to try and reset it back to normal to no avail.
BTW I also can not eject the disc to try that as the eject button does not work.

how did you fix the non-ejecting issue. I’m still stuck there.
