I have solely bought this handy little USB flash drive for even being able to listen to music in the car. On the 16 GB MP3 many fit it, the speed of USB 2.0 drives is for my needs well enough. The Kingston DataTraveler Micro DTMCK 16GB flash drive must be plugged in simple and space saving at the audio system and works perfectly with me. He is also quite inexpensive, I'm going to buy this again if I so a small 16GB USB stick need again.
