Normal Operation
The radio antenna receives AM and FM radio waves. The radio waves are sent to the audio unit through the radio antenna lead-in cable.

The radio suppression equipment reduces engine ignition and electrical systems interference transmitted through the speakers. When installing any new radio suppression equipment components, make sure that a good contact is made at all connections. Remove any paint or dirt from between a component and its ground. Tighten all connectors and screws securely according to the torque specifications.

Possible Causes
- Antenna
- Antenna cable(s)
- Radio frequency interference suppression equipment
- Audio unit
