Badger61- What is the "easy fix"?
I determined that it is the diversity antenna that's bad in my car.
If I remove it, and simply put a length of wire into one of the coax connectors running back to the radio, the reception comes back.
The unit is located behind a trim panel that runs across the cabin just above the rear window. It snaps off. You'll see a black rectangular box clipped to the rear window, and 3 coax connectors. Two are for antennas and one is a data/power wire. The radio sends signals to the amplifier to switch between the 2 antennas, and then chooses whichever one gives the best signal. It is not a simple "antenna booster", although depending on where you're located, a simple booster might work.
Apparently, a common problem is that the rubber that encases the electronics crack and damages the board. Mine has the cracks. I carefully peeled back some of the rubber and found at least one surface-mount component had been pulled apart by the shrinkage of the rubber. But that rubber is impossible to remove without damaging more parts. I design and build circuit boards, so I could repair it if I had a schematic.
