AM radio reception - WTB amplifier
03 SL55 AM radio is lousy with top up, great with top down. Two different antennae, one on the rear glass assembly for top up, one somewhere else for top down.
A DIY manual page states that there is an antenna amplifier on the rear window assembly used when the top is up.
I haven't seen it (yet). I suspect it's either gone or malfunctioning. Anybody have one for sale?
