I am a new owner of a 2007 4th generation LS 460 and just noticed that the calendar no longer shows past 2024 December 31st, this in turn affects all my timers on all maintenance going forward. This simple fix of a bios flash of the audio system is proving to be a surprisingly challenging task. My ODB port reader does not allow for uploads, even though it is phone based, (Blue Driver, excellent product for the price for amateur mechanics like myself) There is no USB port visible on the car to download and flash the bios myself if I could find the software, and third-party dash replacements don't seem to be there yet.

I have contacted the nearest Lexus dealer and they were stumped. the latest map update for me was from 2016, that they could guarantee worked, and the update was called a CDDB update, which there service department said was back ordered and they could not guarantee that would fix it either.

Any thoughts or ideas folks would be appreciated folks...

Perhaps there is an odb to usb adapter I could purchase to facilitate the installation if I could download the software on this or some forum.

 

I also noticed it is stuck in 2024. And trying to add anything in the calendar or maintenance says to choose a date before 2025. Very odd they included that message when you try to do it. There's intention in that clearly. I'm not sure if they planned to update it through the nav updates over time or limited on storage.

 

Use 2005 and 2015 instead of 2025, you will have to live with not matching weekdays.

 

then why would i not just go to a year that matches week days? Also, how do i even change the calendar? Ive looked everywhere and cant find it
