    I have the same problem and was told that my amp was not communicating with the radio. I changed it and wham. Sound back on. No need to replace the head unit. Hope this help you guys.

    I have the same problem. I lost sound all of a sudden, and I am getting the personalization error message as well. But, I also noticed that my cruise control is inoperative now. I accessed the amp to inspect and found that upon removing the plastic cover for the heat sink, the fan was not plugged in. I am getting U2100, U2122, and U2124 - loss of comm with radio and amp. I suspect the amp overheated once the fan disconnected, but I'm am baffled at the cruise control and there are no codes pertaining to it, well other than the U2100. I am planning to replace the amp but is the cruise somehow related to the amplifier? Is the amp going to make the cruise work again?

    Same personalization message is fine. My cruise control stoped working briefly I disconnected the batt and I get sound ehen I touch the screen but no radio. Time to dump and run. Exactly why I lease luxry cars.

    Well I didn't dump the car...because I love it and it only cost me $147 for a used amplifier including shipping from out east and 15 minutes of my time to swap them out and everything (including the cruise control) works again.

    wish i saw this last month could have given you some guidance with our fix. we had the same issue a year ago and after multiple failed attempts to fix i gave in and purchased a used "working" amp online. now we also have sound, can adjust things on the nav and most importantly can hear the turn signals! lol 07 STS loaded 77k miles with a new timing chain "thanks gm extended repair bulletin"!
