Does anyone know how to upgrade the navigation system without paying the outrageous price at the dealer for the disc? You can buy a navigation system for less than they want just for the disc.
If you're going to have latest version, you're going to pay top $$$. Say you have version 5, why pay for upgrade 12 when getting 10 which has much more than 5, on Ebay for say $99 instead of $200 for latest.

Not everyone actually needs an upgrade. An upgrade includes new roads and road changes (completions of expressways, etc) and changes of Points of Interest. I rarely use POI but was anxious to upgrade when the new nearby expressway was completed.
You can go to the Lexus web site and find a detail listing of all the changes by state. You can then decide if an upgrade is worth the money.
