If you are thinking of buying a new car audio system you should definitively start to have a look at the offering from Korean companies. Korea is the leading country when it comes to MP3 players and PMP’s… so it’s quite natural to think that this kind of expertise should make their car audio systems “rock”. The company called Boss presents a rather different solution with (optional) Bluetooth and an SD card reader and USB port that can be used to read almost anything that contains MP3 files.
