So I replaced the stock Pioneer head unit in my 2008 SS with a new touch screen JVC. I replaced the stock unit because the radio would stop working, just start providing white noise after a while. Seems like it was faster to fail on warmer days and longer on cooler days. While my wife is completely overjoyed with the new head unit and it's support for Apple CarPlay the radio still does the same thing, though now if you turn the radio off for 10 seconds it seems to start working again and then not stop. I'm at a bit of a loss for what might be going on, unless somehow the OnStar or a hidden antenna amplifier is messing with it. Does anyone have any clue where to look next?

 

The antenna amp is at the base of the front antenna, under the headliner. It gets power from the pink wire, ground on the shield of the coax.
If you don't want XM/Sirius or OnStar pull fuse #24 on the BCM.

Maybe somebody in the past messed with wires and hooked the antenna amp to the RAP.

 

I've owned it since new so nothing's been messed with other than me installing and uninstalling an iPod adapter and the new stereo. Anyone ever heard of the antenna amp going out? Any reason to pull fuse 24 even if we never use those things?

And thanks for answering.

 

the amp have been known to fail.
OnStar has been known to repeatedly try to "call home" and kill batteries.

 

Someone else just had a problem with an aftermarket stereo. It turned out to be the iPod adapter. Or was that you?

 

That was me. This is different, after a while the radio starts playing white noise on both AM and FM and I'm trying to understand what might cause that. With the original stereo on it started it wouldn't work again till the car had been parked. With the New one turning the stereo off for 10 seconds brings it back to life and then it so far has worked for the rest of the drive.

 

Well unless you believe in incredible coincidences, at least you know it was never the radio. I assume when you have the problem, other inputs like CD or USB work fine?

Sounds like maybe a bad capacitor or something in the antenna amp.

 

How hard is it to get to the antenna amp and can I get a replacement?

 

I hear it requires removal of the headliner so I've been stalling, have not exhausted other possibilities. I do like radio.

 

You have the same problem?
