Re: AM Radios in Cars - USA
My last car was new in 2021. It is a Seat with AM included on the radio. But... the radio picked up a huge amount of interference on AM. I learned how to trick the system. Select manual tuning, search away from your station, then search back to your selected station in the opposite direction. Hey presto, some suppressing circuit kicks in and reception is fine. I reported this to Seat Head Office then, maybe coincidentally, the car had a software update which cured the issue and AM is now perfect without the trick. It can be done but I don't think that car builders see AM as worth spending any time on.
