Display Unit buggered.

[PJDB]

Tricky one here, I am getting intermittent problems with the Multi Function Display in my LS430.

The problems I am having are exactly the same as what is described in this Toyota Technical Bulletin which was released for the 04 Highlander, Land Cruiser and Prius.

The fix for it seems fairly straight forward, however, I cannot determine whether those cars share the same Display Unit as my LS430?  It's the same year so seems likely that it does?  Can anyone confirm whether it's the same unit for the LS430?
