2013~2016 CX-5 Head unit swap questions

When I trade up to another CX5,are the radios interchangeable between versions of the early CX5’s and Mazda 6?
I have a 2015 CX5 GT with an aftermarket radio and I don’t want to trade it in with it.
Can I buy one from eBay and just plug it in and go or were they coded to each vehicle?
I no longer have my original one.
I'm nearly positive they aren't coded. I've never seen a coded Mazda radio.

As to if a MZ6 radio will work, they certainly do look the same, but no clue if it really *is* the same.
