Okay, so I have an '04 GTP with tan cloth interior. I hate cloth but I got a good deal on the car and figured I could change out the inside later. So, I found some tan leather seats out of an '04 that are in really good shape... But they are heated. My car doesn't have heated seats. So, I was wondering if I got the AC control with the heated seats buttons on them would it work or is it more involved than that? Also, the car doesn't have HUD. What all is involved in adding that to the car... Basically, I have a car that is in the shape of a GTP... LOL, very base model... Although it does have a sun roof...LOL... Any Ideas??
