Question on Steering wheel radio controls

[Guinnessboy]

im in the same boat, but for me its the track advance buttons...both up and down....but it only does it randomly...if i turn the radio on and off it will sometimes work and sometimes not......looks like i will just have to use the touchscreen instead to change songs.....I have the Kenwood

next place i'd start looking is the path the wires run through the steering column. I've had a number of issues in past years w/ gm tilt columns either pinching a wire or wearing out a contact- killing some or all steering wheel functions.
