Have had my 2015 TLX for over a year and love it. I live in CT and during a cross country trip my rear window was destroyed. I had it replaced in CA but when I got home to CT I noticed that my AM/FM reception stinks. It used to be really good. I suspect the AM//FM antenna is in the rear window glass and was not connected by the shop in CA. My local Acura Dealer SM says it is in the fin and there is nothing he can do.
Can anyone point me to something that spells out the location of just the AM/FM antenna so I can pursue this with the dealer?

Thanks
Carl
