Lost Radio chip set

I just upgraded my Eonon VW Android head unit to KitKat, everything went smooth other than now I have no radio. Went to factory settings and have only 2 chip sets and have tried them both, still nothing. I am not very good (new) to Android. Is there anything I can install to get back the other radio chip sets ? I use the radio a lot and really don't want to tether to use an app every time and use my data to just listen to local radio (Cubs, Bears, etc.)
