How do I reset my Veloster display?
Use a paper clip or pen and stick it in the reset button next to the eject button for the CD player.
How do you reset the touchscreen on a 2012 Hyundai Veloster?
To fix the problem, I held the reset button for 30 seconds [not one, five, or ten but 30 seconds]. This was recommended by someone online on a different forum. It really worked as if the device is now back to normal as it was the first time I brought the Veloster home.
