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?
I’d start by looking for images of the rear side of the stereo to determine if the electrical connectors are the same. If you can find electrical connection diagrams that’s even better. If they all match then you’d have reason to dig deeper. I’m assuming the units are about the same size, but I have no idea since my Pilot is a 2005.
If you decide on aftermarket instead check out Crutchfield.
