I have tinted windows on my 09 CLK350 - believe they're at the state maximum for GA.

I've noticed that FM radio reception in this car is not that great compared to other cars of the same calibre that I ride in. Some stations are quite bad, and although I don't expect it to be the quality of my wife's C250's HD radio - it's markedly worse. (I have the Audio 20)

I've researched about tinted windows and that certain types can interfere with the FM signal. Is this a known issue with the Audio 20 or is there a good way I can identify if the tinted windows are the source of interference?

Modern metallic tint can cause issues. Also, the tint shop may have "disturbed" the antenna amp, which is attached to the glass, just above the headliner.

I had this issue after my tint, but with my AM radio didn't work at all and my key fob stopped working unless I point it directly at the IR sensor. Idk how, but just recently my AM radio magically fixed itself but the key fob still doesn't work. I miss unlocking my car from a distance :/
