Definite Police Interceptor model and Franchise is correct,.....Hopefully JMR will chime in soon but I am pretty sure they make aftermarket kits that can convert that blank off panel to active AUX and or USB input.
I didn't see this topic. I believe the PI has a different designed internal dash at that area. Take off your flat bezel and see if there is a big hole there that would accommodate the pocket. I know for sure if you have a heated steering wheel there isn't a pocket there.
As far as adding AUX AUDIO that can be done and I do have a kit for that. I always say SYNC can't be added...well for the purpose of this thread I will say it likely can be added but the parts and time and complete tear down of the interior of the vehicle (dash, headliner) would likely make it not worth it. It would require a lot of time, a lot of parts (including a completely new dash wiring harness), research and work to complete. Just buy an aftermarket kit, much easier.
