iPad as a head unit control

[CamaroAJ]

I plan on using my iPad mini to control my HVAC, Windows, and locks on my Camaro with my Infintybox wiring. Since I'm already going to have this in the dash I want to mount the radio in the trunk and control all functions from the iPad. Does anyone know a head unit that is capable of doing this? I see Sony has a few radios that say they can, but the link that had all that information is a discontinued unit. Google hasn't been very helpful unless I'm trying to put an iPad in a VW.
