anyone know how to play dvds on a stock navi?

its an 07 escalade, and i remember way back some guy on this forum was able to mod the navi on tl's to make it work. i cant remember who the member was but he was somewhere in jersey....anyway if any of you guys know a way of doing it, or know anyone in jersey that can do this for me that would be great.

thanks

 

In cadillac's, i know there is a way to punch in a code to unlock this feature, I remember reading somewhere that it was combination of 3 numbers and a music button??
