Here are a collection of web pages that I linked to a long time ago. They have all been taken down, but are still available on the Internet Archive, also called the Way Back Machine. It is safe to say that you probably will not find these links elsewhere, except on the Internet Archive versions of this page.
There are a couple of articles on car and auto radio reception on the Crane web site.
More than links, you get commentary that tells you a little about what you will get before you click. This page is for your car or truck, I have another page for home and office AM radio.
Once again the Australians have addressed the subject at the ABC site.
The BBC used to have a web page on radio reception in your car, it is for both AM and FM. Remember AM is usually called medium wave outside the USA.
This was from a web site by Colorado Public Radio does not have much but it may have some things that others do not.
Satellite radio works in your car. Catholics can get EWTN and another Catholic channel they created on Sirius Satellite Radio. The Catholic programming is in English, but there does not seem to be any Catholic programming in Spanish.
Another solution is to record your favorite radio programs at home and play them back in the car. I have a web page with tips and links on timed radio recording which may help. Of course this page is currently on this web site.
