2004 BMW E46 325i Poor AM Radio Reception
I recently purchased a 2004 BMW 325i, and I love it! However, I have noticed that whenever it rains the A.M. radio reception gets very ugly and garbled. Its fine during clear weather, any ideas?
We do field many questions revolving around poor radio reception (especially AM) in the newer BMWs. Often this can be cured (or improved) by disconnecting all of the antenna connections and applying the DeoxIT contact enhancer solution. Your 325i antenna is in the rear window and the amplifier connections are in the rear C-Pillars behind the interior trim panels. The C-pillar trim panels must be removed to access the amplifier connections. The Bentley repair manual will address this.
