Forgive me if there's another thread about this topic, but I couldn't find anything using the search tool.
I have a 2007 Tahoe LTZ with the Bose sound system and no navigation. Overall, I'm happy with the system, with one exception...
Whenever I use the Aux Input on the front of the CD player I can hear a high-pitched whistling noise through the speakers. It only happens when using that specific input. No other modes make the noise.
I tried different MP3 players and different cables, but the problem remained, so I asked the local dealership to take a look at it while they were doing some other work on the vehicle.
At first, they tried to tell me that it was my cable, and I needed to use the official GM cable, but I was able to prove to them that the cable had nothing to do with it.
The next thing they tried to tell me was that I needed to purchase a "ground loop isolator" from Radio Shack to eliminate the noise. They even printed out a Technical Service Bulletin from Chevy that described the problem, and had specific Radio Shack part numbers that I needed to purchase.
I went to Radio Shack and found the parts. They allowed me to test the parts before buying them, and (of course) the sound did not go away.
So, I called the dealer and told them that I wanted them to replace my radio unit. He said that he didn't have a problem with it, but he doubted my extended warranty would cover the issue.
I called my warranty company and explained the issue to them. They told me that it was unclear as to whether or not they would cover it. My warranty covers all audio/video components for "mechanical failure", and they couldn't say with any certainty if this issue would be considered mechanical or not.
So, my fear is that Chevy won't be able to fix it, and my warranty won't cover it.
Has anyone else had this issue? Is there a solution?
