I think he wants to know if the '17 ES radio has different connectors than the '14-'15 DE/ES radios.
Just tossing out a random thought...
$200 is close to the cost of a quality aftermarket head unit that has higher power, pre-amp outputs, tons of sound customizing options, backup camera input, auxiliary input, DVD player, etc. I have a Kenwood DDX393 and it's only about $50 more than this used radio. I use this head unit to power the 4 door speakers (which I gave upgraded) and it's plenty loud. Well, I have an amp and a subwoofer, too. But that's another story.
Also keep in mind that the dash piece that surrounds the 2015 radio is different from the piece in the 2017. I think that dash piece is something like $100 from the dealer.
