It is not something that I intended to buy, but honestly, this things is not a common product. I bought it at local online store for less than US$17 and it is SONY GMD-700, a 1 Din Auxiliary Box but it is expensive in my opinion for only a drawer.
Last week, as usual in my daily working days, I am stop by to my favorite audio parts store, just for looking around. There are lots capacitor lining up in the shelves and I just wondering that I has one more things to do in my CD Player here . So I bought some to upgrade my CD player.
