My Ride: Silver 2002 E46 M3
So I have this '02 M3 SMG, no NAV. I have a BMW iPod adapter installed, satellite connection and no CD-changer. I bought this M3 used in '07 and the FM reception has sucked ever since. I can pick up about two or three stations period. I live in Hampton Roads (Virginia) and we get very good signal from the local stations which total about seven or eight, however, not in the M3. Today I had some time so I removed the LH C-pillar cover and checked all the connections to the radio amplifier (N8). Everything looked good. I removed connector X424 and connector X1143 (what I assumed to be power) for the AM/FM amplifier, tested the voltage (12v and about 5v on each of the two leads respectively to ground) and then reconnected it. I tested the radio and FM reception WAS PERFECT!! I could pick up every station and then some! I actually programmed the presets during this time and all was right in the world. I then turned off the radio, turned off the car, removed the key, re-inserted the key, turned on the radio and NOTHING! Back to square one - no reception! The only thing I can think of is based on the fact that power is always supplied to the AM/FM antenna amplifier ALL the time so when I disconnected it, it was reset and worked? But not sure why, after turning off the radio and car, no reception now?

Any help would be greatly appreciated.
