Sony DEJ017CK Walkman Portable CD Player w/ Car Accessories
I plugged this set-up into my car with great anticipation of being able to listen to discs again, but was sorely disappointed when a hissing sound emitted from the tape which connects the sony system to my VW Passat's system that was louder than the pathetic volume of the player.  Maybe this works better in other cars, but it was terrible in mine. I returned it.
