Yes, I think that's a description of the problem I encountered, and their solution is correct.

However, in their description in that bulletin, they are glossing over the fact that the instructions were flatly mis-labeled. The bulletin hints that the fault is with the head unit not having a separate antenna wire. This is not true. If I had hooked up the blue/white wire to the tuner module's antenna wire, we would have gotten no sound except when the radio was on. As I said, the instructions simply had it backwards.
