SYMPTOM/CONDITION:
A customer may experience a buzzing or clicking-like sound coming from the vehicle radio speaker(s). The sound may be heard when the radio is in AM or FM mode. The clicking-like sound may sound like Morse code.
DISCUSSION:
The hardware construction of certain cell phones may generate frequencies that can interfere with the vehicle radio system. These frequencies may result in buzzing and/or clicking-like sounds in the vehicle radio. GSM type cell phones are more prone to cause this possible interference condition, though other type cell phones may cause similar buzzing and/or clicking-like sounds.
This condition can be easily corrected by instructing the customer to move their cell phone away from the immediate area around vehicle radio system (radio, radio amplifier, antenna, antenna lead). DO NOT replace any radio system component in an attempt to address this condition.
