Likely I have managed to find a comparable update onllne but it's a little bit to dear in price. I don't mind spending the money if there is no cheaper option. Any ideas of places I can purchase at reasonably cheaper price than £115 I have been quoted which is inclusive of postage. Yes I have a 7 inch screen that is 17 cm diagonal on screen

Yes you are right I have seen some numbers though there is no pz before the numbers. Here are the numbers on the disc 86271-24125 & 86271-70v315 (2005-2006 ver.1) As for the size of the screen I think it's seven inch will measure and let you know

Thank you but unfortunately I there is no part number on the DVD making it more difficult to chase up an update DVD. I shall continue to pursue with the Lexus map update site

Its running a uk/Europe disc just out of date

Need help on how to update my in built Navigation system for my Lexus Altezza IS200 2001 Japanese import. It has a dvd navigation module mounted in the boot/ trunk .help most appreciated.
