does anyone know if it is possible to put a switch in or bring power to a certain pin in or anyway for me to be able to mess with my navigation while in motion.....

Right now if i'm not in park it won't let me program any destinations or anythign and there has got to be a way around this.....Any ideas?

Read down a few post.

You can also scroll the map to a particular street and select the street while driving with no modification. The system only locks up the typing in of an address. ;)
