It is the Head Unit that has the HD radio - it isn't a separate part, so you would need to get an entire head unit. I am pretty sure it doesn't matter if it is a hifi car or not, I think the hifi is all in the amps and speakers and the signal from the head unit is the same. The head unit doesn't specifically say hifi or logic7 right on it like it will say HDRadio on it, but don't quote me on it. When I replaced my Nav to upgrade from CCC to CIC, the only difference in head units was HDRadio or Not (as europe didn't get hdradio)
