The same is true of other items such as using Amazon Alexa to voice command features. I can Alexa remote start our 2017 but not the 2015. Different hardware and software. If Hyundai tells you it cannot be done then it probably cannot. The same was true with GM vehicles. Some models years and specific radios were eligible. Others were not.
You can of course stream music via Bluetooth. Voice directions from a cell phone based GPS app as well. No display obviously, but.....It is a workaround for some of the features you may want.
