Hi guys, the headunit in my 03 coupe stopped working today, it says CD ERR FO....i tried all the little tricks i found on here that some guys had luck with but nothing worked.

I have a complete headunit from an 05 that someone gave to me awhile back and i was wonder if it would work in my 03.
Just by looking at it i can see some parts are different, is it possible to use just the HVAC from the 05 and keep everything else like the buttons and stuff thats in the car now?

Sorry if i didn't explain clear enough, the part in the pic is what i want to change.
