Every person who owns a car wishes to have a DVD player in his car. But it should have a good DVD player that possesses all the features. Today, high-tech DVD players are designed with lots of useful features that meet our purpose. These car DVD players are a great source of amusement especially when you are going for a long trip. The various functionalities at the user end include television watching, GPS and operating different CD and DVD formats.

One such feature is so called "AF'. It is the short form of "Alternative Frequencies". Now you might think that what exactly does AF mean? Look for this feature also while buying a car DVD player.

Some people think that there is any mystery behind this functionality of AF. However, this is not true as many shopkeepers offer this feature throughout the world. Those who love a particular station to listen to, is a great choice for them. It happens many times that a particular station signal becomes weak and it cannot be sensed by the player. For instance, you are on a drive and there is any spillover or interference from nearby radio frequency that distorts your loving station signal.

This happens many times when you go on a long car drive and suddenly your radio station creates noise due to some interference or spillover due to closely situated other radio frequencies. As a result you are not able to enjoy the specific radio station.

Hence, AF allows the radio tuner of car DVD player to retune to other higher frequency band which is taken from the same station or sent from other station when your last signal begins distorting. So, AF offers complimentary signal to any particular radio station signal by scanning any other broadcast signal.

In addition, AF will tune automatically for the any supporting signal available when the last signal gets crowding out and weakens below a particular level.

Some people prefer to buy the car DVD player only when AF is embedded in the player as they love to listen a specific station and what all it broadcasts. So, as long as any country which uses the player allows various radio stations to match to the complimentary signals, AF will function as shown. Sometimes user would not even notice when AF overtakes the previous signal.

Although, there are some disadvantages also of using AF in car DVD players. Customers report that the player sometimes go in a loop, searches through the background for some stronger signal. Second is the spillover effect. This effect when comes it interferes with the existing signal and distorts it creating a lot of noise.

It also affects some activities of the player like static, hiss or radio station information is sometimes lost on the screen. Consider these factors also before you go to buy car DVD player.

So any person who desires to purchase a good DVD player, with AF included with all other features is a good reason for considering so. Today's high-tech players are excellent entertainment source electronic devices which offer their clients a good satisfaction which old players could not offer. Therefore, this is the right time to buy a device with all such great features.
