How do I override gps Navigation System on 2008 Lexus RX350 ?

I know that there is a way to override older Lexus gps Navigation Systems through a series of taps which get you into the diagnostic mode. From all the research I’ve done, this is not possible on the later model cars. From what I have found, the only way to “fix” the Nav System is to take apart the dash and cut some wires. Not something do myself!

The best override, is the off switch and an atlas. I am not sure why you want to override, but I feel that the Nav systems are just another gadget to take the driver’s mind off what he is supposed to be doing. If there is no off switch, then cover the screen with cardboard.
Do you want to diagnose your vehicle? Take it to the dealer, that is why you pay hard cash for it. If you just barely can afford the vehicle, why have it in the 1st place, right?

I regularly visit Lexus forums and nobody has come up with an override for the 2008 models yet.
