I talked to PAC awhile back, they said then that they didn't test them in the 2013's yet and couldn't guarantee it. After reading up on it here, I went for it, but then work killed having the time to do it. I finally got to it today (been working on it a little over the past few days). The only issue I had was the PAC instructions say it pre-programmed for the steering wheel controls and you only need to mess with it if you want to change options. Well, I put it together and I had no steering wheel controls. After a few moments of rechecking everything, freaking out, and then taking a chance - I reset the PAC. After a reset, all is good.
My Jeep was an earlier 2013, I think it was a Sept. build date. I have the S package, without premium sound (no amp or sub).
