I had car radios back in the day that had physical mechanical buttons for setting stations ( the kind where you tune the station, pull out the pushbutton, and then push it back in) and you could do those out of order. Honestly all of my cars had this capability.I only put 2 channels out of numerical order and I didn't even realize that they had been put back to ascending order. That stinks. Hyundai needs to address this ASAP. Sorry for the bad info.
