03 explorer radio swap question?
 

I have a 2003 explorer eddie bauer with the premium sound package and the
factory sub in the rear. I was wondering if it was possible to swap my radio
with one with the navigation system from an 04 or 05 expedition. Are the
radios the same size in the expedition as in my explorer? Would it go in
with little modification. Any input on this would be appreciated.
Thanks
George
