Verify the antenna lead is connected to the antenna jack on the rear of the car stereo receiver and that the connection is secure. The antenna lead should not be connected to any other jack.
If applicable, change the tuner settings of the car stereo between the Local/Distant (LX/DX) station selector to switch the tuner sensitivity.
Class D amplifiers may also cause AM reception problems. If you have an amplifier connected, disconnect the amplifier power. If the AM reception now improves, the amplifier is the problem. There is not a fix for this other than lowering the GAIN feature on the amplifier, if applicable.
Try resetting the unit.
There could also be a poor ground connection. We would recommend that you contact your local installer to have the ground connection checked.
