Summary

Mobile Telephone Microphone Poor Performance Condition/Concern Some customers may comment when using the Bluetooth® phone system in their vehicle, the person on the receiving end of a mobile telephone call states the audio sounds muffled, distorted or has static. The foam patch on the back of the headliner at the microphone mounting area may have come loose. This foam is a sound barrier for the back side of the microphone. If the patch is detached, it allows unwanted noise to interfere with the microphone operation when making a phone call.
