I have 2011 Pilot Ex. I like the newer style of the 2012-2015 radio. I don’t need the navigation. Can I swap in the newer style factory radio? Also I have Digital a/c controls. And don’t they come with Bluetooth?
If you can get the full set of components (display module, audio module, climate control module), you might be able to stuff it in, but is highly unlikely to look 'factory'. It might be compatible electrically though you will definitely need the pinouts for both 2011 and 2012 systems to make sure connectors are compatible.
In addition to the dash stack, there is a handsfree link module that goes in the bottom of center console - that is the one providing bluetooth. There is also a microphone module in the roof next to map lights. There is an AUX jack assembly and a USB jack , in the central armrest compartment. Plus all the wiring harnesses connecting it all together.
If the wedge -shaped portion above your audio unit is solid plastic, you might be far better off going aftermarket.
