I have a 2015 Hyundai i25 (not bragging, just stating the facts) with a JVC Stereo (model KW-V21BT). After doing a soft reset the media controls on the steering wheel no longer work. There is a setting to map the controls under "Settings":"Steering Remote Controller" with the options "Set" and "Initialize" but the entire line is greyed out.

I have tried doing another reset and even unplugging the battery but neither one had any effect.

I am hoping that I don't have to try to remove the radio and play with the cables. Any suggestions?
