Hi all, hope somebody can clear the confusion i have got with the updating of my Sat Nav Disc. I have a 2004 RX300 SE-L. I want to get a newer disc for my Sat Nav. I have put my old disc codes in the update site and it as told me i want a disc PZ-485-X01EU-10 which is 2010. All the discs i have seen for sale give a part numbers like 86271-60W372 86271-60W382 86271-60W393 . Can anyone tell me what part numbers i need, help i am very confused. Thanks
