1. Unplug the aerial cable at the rear of the radio. Take a resistance reading across the screening of the cable and a good grounding point. The resistance should be < 1 ohm.

2. If the resistance is not OK, check the grounding of the aerial to the car body. Be sure to check the ground connection at the aerial rod (mounting fixture).


3. Try fitting a new aerial cable loosely in the car.


4. Try fitting a new aerial.
