I have seen posts here indicating that the 2002 Nav update for the LS430 comes with both a new DVD and a new ROM to update the firmware in the nav computer.

My dealer tells me that this update is a new DVD only.

FWIW, he is also telling me that the Nav computer in the LS430 was changed/upgraded as of about May 2001 of the '01 model year, and that the same DVD works in both old and new computers.

Does anyone know for sure whether there is a ROM update also, and if there is, can you let me know what features are added?

Basically, I am trying to determine if there is a ROM update for my Nav computer that will provide the same new functionality (whatever that may be) that is in the '02 model year nav computers.


Thanks,

I believe there is a new ECU for the 02 NAVs over the 01 NAVs but they are NOT plug compatible... It is a long story, but I found this out in dealing with some usability issues on the Integrated Lexus Phone - the 02 Phone is NOT compatible with an 01 model year and vice-versa. If you attempt anything of the sort, you will disable the NAV. Therefore, logic tells me that they are NOT plug compatible.

But don't take my word for it, check with the parts manager and see if the part numbers are the same. If so, get them to replace it with the update if it has the same part number.

Good luck and let me know what you are able to find out!
