How do I fix my navigation system? my car is a 2009 RX 350. The dealer told me it would cost about $8,000 to change it. Does anyone have that problem?

I have a related problem with a 2007 RX350. I was told by the dealer no less that there is a way fo disableing the power on prompt that asks you to agree not to use the GPS while driving. Its really annoying to have to press this each time you sart the car. I am worried that in the long run that this will lead to a failure of the touch screen. Any body know what the secret handshake is? I can be reached on hotmail if that helps. Fred0723
