If I am listening to my radio/CD/XM or HDD and I turn off the ignition while my radio is still on and jump out the car to run into the store (less then 15-20 min) when I start the ignition again the radio display screen comes on but NO sound out the speakers - after a few seconds the display sceen shuts off and then I have to press the power button no less than 3 times and up to 12 for the display screen AND audio to kick in. I've taken it to the dealer 3 times and they swear they can't find the problem.
Please help...I'm a Cadi girl... and I love my CTS. This radio issue is frustrating

It sounds like this sort of issue can be caused by a loose connection in the fuse block in the back of the car by the battery. The upper portion of the fuse block there is a big connector with a bolt in it. It sounds like there are two designs and it changed in 2009. If the dealer isn't helping and you want to give it a look yourself, you just have to take the battery door off in the trunk. The fuse block and connector are right above the battery. One connector design, the bolt spins freely when tight, however the other design has a torque spec and you can break things by over tightening. Don't exceed 35 in-lbs if you try to tighten it.

I'm sorry that you're so frustrated with your CTS (particularly the radio), and can understand that three trips to the dealership for the same concern without a resolution would only add to any frustration you already had. If you would like for us to follow up with your dealership on this, please send us a private message with your name, phone, address, the last 8 of your VIN, current mileage, and the name of your involved dealership.
If you were going to look into the fuses as mentioned by V Wagon, your manual does have a section on the electrical system beginning on page 5-114 that provides fuse diagrams and other information.
I hope we're able to get this resolved for you soon!

I'd take Katie up on her offer. It sounds to me like the entire unit should come out and a new one go in, but there isn't going to be any test that is going to show particularly what the problem is. I hope that some engineer can fix this for you.

I have heard of an issue where the radio won't power up after a restart. I believe it was traced to a loose wire under the driver's seat. Doesn't sound like the same issue as yours powers up. Could still be a bad connection or ground I guess. Sounds more like a problem with the head unit (Radio)
