"Navigation when you want it- unless of course, you are moving"

Lexus removed the Override from newer DVDs:
It's possible they removed the override because getting into the menu was risky and people (like myself) accidentally killed their systems while in the menu.. Who knows?

Sure it's a distraction for the driver to enter in addresses while driving, but it's easier than trying to pull up a Google map on your cell phone while driving. In any case, it should be enabled so at least a passenger can enter in an address. There are plenty of other cars that allow address entry while on the move...Mercedes, Honda, Acura, etc.

I found the following the other day during my search for a resolution to my crippled Nav system.

Quote from the webpage:

With the release of 2007 models and the 6.1 Navigation software package, Lexus removed the existing 'override' that had been present in their cars since at least 2000. That override feature (a series of on screen inputs) had allowed the use the Navigation and Bluetooth Phone systems while the car is in motion. In a 2007 Lexus, you must either stop on the side of the highway or take an exit and park the vehicle. In some cases, prospective buyers were misinformed that the override was still present. If you are not yet a Lexus owner, consider that 50% of the people who have signed up to this website would not have bought a Lexus if they had known this limitation was in effect. Please see below and the comments page to be an informed consumer!
