Is there a cable that will allow me to plug my RazorMax into my car stereo?
Usually, you would use an "Aux" cable. If your stereo has an Aux input, you can buy a cable at Walmart (Electronics Dept) for something like $10. I have a hard time finding them in Walmart due to the layout, but any younger worker should be able to point you to the right place.
