I didn't have navigation but everything else sounds exactly the same as what happened to me. My ac would stick where ever it was set at when everything would go out. Eventually it went out and never came back on. Took it to the dealership and was told the head unit was shot and had to be replaced. Almost everything on that console, heat, AV, ect is powered by the radio. Had to replace it. Whatever you do, DO NOT get a used one! They can no longer be unlocked at the dealership like they were in the past. I learned this the hard way even after my dealership told me they could. GM no longer allows "computer" parts that have previously had VIN information stored in them to be transferred to a new vehicle or "Unlocked". Long story short you're going need a new head unit and the dealer will have to install and program it.

..

Any idea if i purchase a new one from the dealership will it come with codes so i can install and program myself?

Thanks guys for all the good info, looks like it will be a new one, dont want to go through the hastle of getting a used one and trying to get it programed.

Well took it to the dealership and 150 later was told that the radio is no good!! Car only has 34,000 miles on it and the radio is broke already?? Ugh!! They said a new radio will be 375 plus labor so close to and additional 500 on top of the 150 I already spent. 650 for a new radio, awesome. Does anyone know how to get the programming codes to unlock a used one if I were to buy one to save a little money?

Thanks for the info Jim. Took ot to autozone and o'riley but they both said they didnt have a reader that would help me out. Ill start going through the other fuese you mentioned. If not one of those then off to dealership it goes.

Hello, I have a 2008 CTS without navigation. From time to time my radio and ac controls will randomly go black and stop working. Sometimes they will come right back on and other times they will stay off for a day or so then randomly come back on. It started with just the radio but now its the entire panel but the clock, traction control and hazards still work. Now they have all been off for more than a week. I cannot get it to record CDs either, when I push record it looks like its working but then says something about not being able access the HDD while initializing. It also seems like it is losing power or the memory isn't working when the car is off because sometimes when I start it the CD will start at the beginning and not where it left off. I love the car but these Radio/AC Control issues are driving me crazy. Any info will help. Thanks
