I know its an option that Lexus already has but how do you apply it? I have rear DVD entertainment and Navigation. When in park isn't it suppose to automatically show up on the screen? Do I have to adjust anything? This is for the 2004 Lexus RX330. Also, the different Navigation colors I changed it and I didn't see any color change? Please help, thank you!

 

In order to watch DVDs on the nav screen, you have to put your parking brake on.
