My 2008 C300 AM reception is completely gone, it can't pickup mainstream stations in the city where it used to before and every other car I drive can. Also, I've noticed reduced range with the remote.

Anyone know where the amplifier is and how to remove it? I'm guessing the headliner has to be dropped. Perhaps if there are any DIYs for the W203 it would be similar, but I can't find much for that either.
