Some customers may complain about a whine or hiss noise heard in the headphones or through the audio speakers when playing a DVD in the GM Accessories Headrest DVD system. This noise may change with engine rpm and may be described as an alternator whine.

Install a noise filter kit, GM P/N 19202701 to correct this concern. The filter kit includes installation instructions. If the filter does not include a connector at each end, re-order the same P/N filter. Only use this specific fiter.
