Very practical product for those who want to listen to MP3 in the car without wanting to change car radio. Very easy to use. He read an SD Card 2GB without any problem. The only negative point is the file browsing. A priori, one can not select a directory of files. So you have to navigate through to the next track in sequence. The remote control is effective for jumps beaches but it remains impractical. I would also have appreciated a "random" mode. However, for less than 20, it's still a very good price / quality ratio.
