1) There are 2 6 pin connectors in the console along side the 3 pin connector. If you do not have satellite radio you want the unmarked connector. The CDSARS connector goes to the back and is used with the satelite radio to couple over the CD changer (does not work if satellite is not installed)

2) In back of the radio you can either have the unmarked connector plugged in or the CDSARS conector. It should be the unmarked connector. If you are technically inclined you can disconnect the connector from the radio and use an RCA plug with a couple test pins soldered to one end to connect it to a portable stereo. If you hear sound (like i did) this means DICE is working, radio is not. (There are 4 wires at the conector. 2 grounds and L&R audio. Ground goes to outer connector, audio goes to center connector on RCA plugs)

3) There is a service bulliton 65 01 06 SI which has title "No Audio Sound from retrofitted CD changer" This may be related, but I have no way to get a copy of it. (OK got it)
