Just incase anyone out there ran into a "frozen stereo issue" where the stereo plays but are unable to change the channel. I have a fix for you.
Your steering wheel audio controls are damaged. Either the search up or down is stuck in constant search and the radio is locked into the strongest channel.
For a temporary fix disconnect the steering wheel audio control unit and order a new one. You will have to change the channel on the stereo itself but at least you will have tunes.
After being at a total loss since April of this year and even ordered a stereo off ebay, I came across this solution on another web site, thought I would post this fix incase anyone else runs into this problem.
