There are a number of features that modern cars now have DVD players to their users. GPS, watching television, playing a selection of DVD and CD formats … the list is endless.

A typical after-market player is packed with high-tech features that a person can quickly rose to try to do all the abbreviations. One is the FA, so the question is "Car DVD Player secrets: What is AF? Maybe one to assertbuy a player.

In short, 'AF' is shorthand for the so-called "alternative frequencies".

There is nothing really mysterious about this feature, like many car DVD players for sale around the world has to offer, to be honest. But what owners can do is appreciated by many players who want to continue listening to a favorite station, but perhaps not able to do so as one of the station's signal is too weak to be out of the feelings of the player. For example,supposed to drive and suddenly interference or relapse of a second adjacent radio frequency that starts with "crowding out" of your favorite radio station signal.
