Thread: 2004 grand prix aftermarket radio advice

I believe to get the steering wheel radio controls and HUD (I know you don't have one, just saying) you have to do some wiring and funky stuff. I know for my brother's '01 GTP the previous owner had to do wiring and stuff to get the aforementioned to work with his aftermarket radio. Not sure about the 04+, but I wouldn't be surprised if it's the same way.

Don't quote me on this, but I think in general aftermarket radios don't play well with steering-wheel radio controls and HUDs. I could be wrong though!

First and foremost...pick any stereo you want, that is universal no matter what you pick. You need to find one that fits you, I can make suggestions, but you need to read things about what you will like and what you don't like. I like Kenwood stuff, the new DDX and DNX stuff is great.

Second, you need the right wiring harness that is meant to keep the chime working; This seems like a kit that will work. Not sure how you don't have onstar, do you mean you don't use it?

As for the DIC it will continue to work, not sure why you thought it wouldn't. Only thing you lose is the Date.


Kaiser, there are plenty of kits between PAC and AXXESS that give you your steering wheel controls, it doesn't affect anything with the HUD. Not sure what wiring was done with your brother's car but it sounds like he has a rats nest.

Ah, nice to know, well the radio station didn't display on my HUD with the aftermarket radio I briefly had in it - and (as bobc455 said) it messed with the oil change part of the DIC. I don't know either lol, he bought it like that and then sold it a while back.
