First off- try giving more then 20 minutes before complaining about no answer.
Next- the only ways that I know of to add another input to a CD player without an AUX Input is through a CD changer input, or FM modulator, or FM transmitter. And FM modulator is a little box that goes inline with your regular radio antenna, then you input your device. It sends an FM signal (usually really low FM station like 88.1 or something) through the box directly into your radio's FM antenna input.
Its actually for an Eclipse 5440 Deck....it doesnt have changer control or anything....guess I'll have to buy my client another deck. Thanks peeps---Sean
