New Head Unit

[redrider57]

I just purchased a 2004 Grand Prix GT and the stock head unit has got to go. Wondering what all is involved in changing out the head unit. I have done it in the past just wondering if there is any special wiring harness that I need. Its just the basic head unit with no OnStar.

Any Help would be greatly appreciated.

you will need a wiring harness as well as a chime module go to

Metra Electronics - Products

look up your vehicle and the GMOS-01 should come up, this is what you will need
