Maybe it's just me but I'm not seeing the practality of how you'd work functions needed to control a CD player. Bluetooth tech and CD players ...hmmm?
When operating a CD player, there's the need to load the CD player, start, stop, skip, advance ... not to mention control volume, etc. The way I think of most a bluetooth devices, they're designed to fit in ear. They have controls like on, off, and volume and disengage.
