Thanks. Sorry it that isn't the right forum, however it wasn't net-MD related, so I thought "Non-NetMD" was the right forum (My older car audio head unit cerainly isn't NetMD). If you'd steer me to which forum is correct, I'd happily close the topic and repost on the proper forum.
That said, if I understand correctly, the part you mention is what I'd need to go from a mini-plug to an MD head unit in a car? I'll look that part up and try it. Thanks much for the input.
