Are HD radio modifications needed to car? on 2013 Hyundai Sonata

If my car has a non HD radio can I buy an OEM HD radio,used or new & just install it and will it work with no further mods to the car?

You will need to check with the dealer on that one. Too many possible variables and it is too new for accurate information in the non-dealer world
Thank you, I will do that
