I would not use this for music, 1GB is hardly enough to satisfy a music listener. For the price I'd get this and use it as a Flash Drive that is great storage for on the go, but not as a music player.
I have ordered a number of car stereos from Sonic Electronix and all come in excellent packaging, shipment was fast. and the deals were great, and as long as the deals are great Sonic Electronix will be my #1 Place to shop for stereos.
