Hi!
I've just joined the forum, and like you, I have a 2000 Lexus.
I want to update the mapping but I also get the error because I would appear to have a Toyota disc in my Lexus!!
My code on the disc box i think is the same as yours
08664-00921
86271-70V221
99001-01069
You mentioned last September that you recently got your updated disc.
Please could you let me know what the part number is?
(Is it someting like PZ485-T00EU-07 ?)
Also, as a matter of interest, could you look next time you have a few minutes to spare, and see if the ISLE OF MAN is on the map now?
Thank you very much for your time!
Kind regards
:)
