I am so glad I found this forum. I just came back from my Lexus dealer after a routine maintenance. While there, I asked about the availability and cost for an updated navigation disc. My current disc is for 2005. They gave me a total cost of $425, which includes $75 for installation. After reading the threads in this message, I think I should be able to do this myself. My question is: for LS430, where can I find the navigation unit so I can swap out the discs. Thanks and Regards, Bill
