| Perhaps, the car stereo's internal circuitry connected to the phone muting pin is defective in some way. For example, because of an external wrong connection or short circuit, or due to ESD damage. Check out the service manual and schematic for the unit to see if this can give any clues. If there is any complex IC directly connected to this pin, check out its datasheet too. | |
