will any of these fit in a 2004 grandprix do not know what radio was in it someone put a pioneer in it https://allusedparts.com/pontiac/grand_prix/2004/radio_cd_player/

 

Yes it should. OEM radios are typically produced by Delco Electronics or Bose. Let's hope that the stock wiring is still in good shape and that it was not cut up in order to install the Pioneer unit.

all their not cut up even has box to keep the annoying chime when door open with key in

So which radio did you decide to get? Have you gotten it yet? Is it installed?

getting new rotors/brakes and trans cooler then will work on radio

 

That's important too!
