Change Radio

[Jake27]

Actually Loren….I did. And I really do appreciate your reply. if I read it correctly, Your wonderful post breaks down codes and applications of specific radios as based on people if they lose the code. The question I was posing to people was do I have the ability to swap in a newer radio into my 2003. They have the identical part number the only difference is my radio part number ends with the letter A and the one that I am considering swapping in ends with the letter G. My part number is 7L5.035.191A, I have access to part number 7L5.035.191G.  I understand your post as far as codes go. What I was actually asking was if I swap the newer radio in, am I going to have an issue? Is it something that needs to be VIN based? Or do I literally have the ability to just swap the radio in and plug it in and all is functional.

You will still need a PST2 or PIWIS to update the new radio serial number in the DME.
