All most every time when I turn on my turn signal I get 1 or 2 pops from the radio when its turned off, or turned on with my MP3 plugged in but not playing. I have asked the dealer they told me that they never herd of this before. I was just wondering if anyone else has had this problem. I have a 08 LT with a base radio. I tried doing a Search but could not find anything.

 

Got a couple of hits using "radio popping". Here is the one w/ the most post.......
