I just purchased a navigation system for my 2004 Deville with standard radio (i.e. Not Bose) that was installed in a 2002 DTS (this person had istalled it after he purchased the car too).

the radio part number is 25755059

I have been researching this swap but i am confused as to what type of pin swapping i have to do to get it to work.

Has anyone here done this before that can give a little assistance?

thanks
