Cool! The TOY-AUX input adapter works perfectly! You unplug the CD player, plug into the port, and push the Disc button. The display reads Disc 1 and the sound comes through the newly created line in!
Only note: For some reason, the connector is very tight on the pins. In order to get it in, I released the pins from the connector, pushed them back a little, pushed the connector into the stereo, then pushed each pin into place until it clicked.
Hey, at least you know it won't cut in and out over bumps!
Anyway, it works very well, and this store seems to have the best price: (I am not affiliated with this store).
