Hola new guy!
Well for starters you already know how to create a new post.
You started this one!!!
Is the car an '04 Grand Prix GTP or a Grand Prix GT?
If it's supercharged, it's a GTP.
Radio is easy to remove.
Gently pry off the ring around the ignition.
Give a gentle tug around the bezzle for the radio & the a/c-heater controls.
Starting with the cubby hole at the bottom, remove the screws.
I am not sure about any theft control procedure when the radio is removed so I'll leave that for somebody that's smart to address that issue.
