Both my and my wife's car are fairly new. Yet the radios are very bad. In the old days there was some adjustment that could be made called trimming. Does anybody know if there is a procedure for optimizing on todays radios? AM.

It is surprising, car makers have improved their radio suppliers specifications a great deal since the seventies; perhaps you drive in a difficult propagation zone.

The antenna trimming on older car radios is for the AM band only. Modern ones are fitted with circuits of automatic gain, cheap but work.

The FM band has no user adjustment and generic modern radios are built for cheap price rather than sensitivity and selectivity.

Yeh, It's the AM band that is bad. I suspect that these are cheap radios because my truck is an 04 Dakota and my wife's car is an 05 Prius. I think they have third level quality stuff that they throw into these cars. These cars are too loud, have bad sound and rough ride. All could be fixed. Help.
