The sonata doesn't have hard preset buttons. It's all controlled on the touch screen. Does ur Elantra have hard buttons for presents?For both my Elantra and Tucson. You just hole the preset button for a few seconds and it locks onto that station your on.
Just in case: I don't know if the radio might do an automatic scan when it is turned on for the first time. I suspect - not, but I don't know for sure.Someone at the dealership before I got my car put random crap in all the radio presets on my '18 Limited with the Ultimate Pkg.
The main purpose is to help distinguishing this card from others:OK.. you got me... I want to know what the purpose it serves is?:wink:
Amazing. I was told the same thing about tuning to the next preset on my radio screen from the passenger side when I asked about using a button. "You can't." I have to use the touch screen. I don't want to use the touch screen. I can't. How about that. Thank goodness I didn't have too many presets when I bought the car. I figured out that you CAN'T delete the ones you don't want. How stupid is that.The simple answer to your question is, you can't. You can't set those presets back to default(nothing). If you only have 3 stations you want, you'll have to reset the radio unit to factory to clear those presets. Easier said than done, however.
