OEM radio swap

My wife has a 2005 Grand Prix base model and all of the lights on the radio went out. I have a friend that is selling a oem navigation unit from a 2006 model, anyone know if it would work in my wife's car. It doesn't come with the navigation ant or cd and not really worried about it but it cheap looks stock which is what she wants. Just need something that she can see and plays radio and cds.

Any help would be great.

Thanks.

not sure, let me know if it works out!
