Hi new here. Looking for some information. I have recently replaced the whole audio system in my 09 350ti. As the stereo, GPS and AC was all tied in together, I have modded the stock head unit so my floating screen pioneer mounts in with it. But at the current stage, the AC controls are on the fascia panel with the standard audio controls. I am wondering if I can remove the GPS control (topside of dash under screen) and replace it with the AC controls from a St or an st-l maxima?

That way I can I can use an after market fascia kit and make it look nice. Instead of having the standard fascia panel just sitting in front dash. I am very hands on and knowledgeable when it comes to electronics. Just seeking advice to see if anyone knows it can be done. Cause I am under the impression that the main wiring harness is the same through all the different maximas? Where it be bottom of the range or top of the range.

Thanks in advance.
