Hello, All,

Is there any reason a modern FM car tuner should lose sensitivity
over time that's not related to the antenna? I have a '99 Passat
with a stock VW radio. When I first got it, I was astonished at
how many FM stations it could pull in. Now, it's down to about
3. I unscrewed the antenna, and there was no sign of corrosion;
I cleaned it to no avail. Any ideas?

TIA,

dpn

that car probably has an electronic amplified antenna...

when you unscrewed the antenna to look for corrosion
did your reception get worse (without the stinger) or stay
the same (an indiscation there is a b problem before the
stinger)..??

Hows your AM? (an indicator of antenna health)

The question is flawed. You have not ruled out the antenna just because
you ruled out a rusted fender. There can be corrosion of the wires in
the cable, or the cable could have become crimped/broken/pulled apart on
the inside. Come back when you've ruled out the antenna using a
temporary (such as a magnet mount antenna).
