    I lost the radio signal

    I pulled out radio units, and found 3 antenna cable. For XM radio, and 2 more radio connector. But none of them gives me a radio, FM simply sizzles. What to do?

    Re: I lost the radio signal

    have u made sure that u connected the small one that plugs into the side? its probaby 1/4 inch in diameter. ballparking but its not that big. its the small circle one that connects to the side. Have u also checked your exterior antenna to make sure it is on all the way. I just got my cts not long ago so i dont know a ton about em but i do believe that they are on the top of the car on the body. just make sure its screwed on all the way or popped on right, whichever it is.

    There are three FM antennas. Two in the rear window and one in the front. All three connects to the box that is held in place by the bolt that is holding the rear dome light.

    The three cables you found for that wing on top of the car is for XM radio, On Star voice and OnStar GPS.
