Yes, jaguarskx, that is exactly what I have. I didn't know, however, about the impedance issue between the two. Is this not an issue?
The sales person at Wal-Mart, where I bought the cable. tried to assure me that a cable with 2 headphone jacks connected to the headphone jack on my MP3 and the headphone jack on my stereo would work! I promptly explained that this couldn't possibly work, to which he gave me a puzzled look & then quickly dismissed my argument. So his credibility quickly plummeted to zero with me!
