Lincoln 2006 LS. I have static in my radio. I am investigating the Amplifier Assembly - Antenna that attaches to the back glass above the head liner. Does anyone know the difference between the Visteon 3W4T-18C847-AB and a Isolator 3W4Z-18K891-AA Radio Antenna Module? Something seems to be “loose” at or near the amplifier assembly. Anybody have this problem? Any suggestions?
