Navigation Upgrade?
Turn the engine on and leave it running.
You have to access the DVD drive which is in the trunk, clearly marked, but it's under where the top goes, so the top has to be up.
Push the eject button, and the old DVD will slide out.
Insert the new one, and close the little door and put things back together in the trunk.
Leave the car running. The screen will say "Loading new" something or other and "Do Not Turn Off Power" (or words to that effect) for about 5 minutes or so. During this time, the DVD is loading a new operating system. The old DVD will no longer work in your car.
When the screen warning goes away, you are ready to go. All of your saved information is preserved except for the "Recent Destinations" list, which will be empty. (If these are important, register them as Marked Points and they will be saved.)
Other than putting in the new DVD and not turning off the power till things are done, it is a fully automatic operation requiring no user input of any kind.
Don't let the dealer charge you to do this.
Happy Motoring.
Now what site is "lexusparts"?
And can some tell me if the Navigation DVD improves the software or if it is just more data. Some things really irk me about the original software, like street intersections input since I don't know whether it is "Main St" or "Main Ave" or "Main Rd" or the 100 other choices. If it only restricted my second street input by those streets that actually intersect!
