I am to take it that Kia didn't have anyone test out there controls system before they released it to the users. On the steering wheel left side you have two up/down switches. The leftmost one controls the volume, and the other one can be used to scroll up and down through your presets on the radio. But that toggle doesn't work properly. If you have your radio turned on, and you have the screen that shows all your presets on the center console, then pushing the toggle up will move you up on the preset list, and down will move you down the list. What you would expect. But if you have the center console display on anything else, you can still move through the presets list using that toggle but if you toggle up then you move down the list, and if you toggle down you move up the list. It is the exact opposite as way you'd expect and contrary to how it works when the radio preference list is displayed.
