As technology moves forward, more options are available for stereos, including a car radio SD reader. This is similar to an MP3 player, but much smaller. SD stands for Secure Digital, and these small cards are used to store information for handheld devices. They are commonly found in digital cameras, laptops and more recently, car stereos. There are several reasons to consider this over other types of stereos.
An SD card is much smaller than other types of music media, including MP3 players or CDs. An SD card can easily fit in a wallet, and is simple to keep tucked away when not in use. If you don’t need to listen to tens of thousands of songs, an SD car stereo may be a great option. In most cases you can get around 1,000 songs on each SD card, depending on the size of its memory.
Also unlike an MP3 player, an SD card is cheaper and easier to replace. Replacing one of these if they become damaged or lost can be as little as $20. Replacing an MP3 player can be well over $100. You can also find replacement SD cards very easily; most retail locations and drug stores will carry them.
For those who have an audio/video system set up in their vehicle, some cards will allow you to upload videos to the card. This can be a benefit if you’re traveling with young children. You can just pop the card into the system and the video will be played on the video system.
