hi, I bought a cd changer for my 01' c320 sedan in chicago, IL. I am trying to install it today. But I am now half way through, and I don't know where is my optic cable for the cd changer, I only see a orange wire with a black "head" but labled with "tel", is that the right one that I need to hook to my cd changer? or there should be another one? and other than that , I think I only see 3 orange wire and 2 of them are already connect to my HU. And I have tried to connect that orange "tel out" wire to the cd changer and power connection, but it still say no cd changer? can someone tel me what I did wrong? thank you tons!!!!!

 

1. Remove the radio.
2. Remove the three CD changer transport keys.
3. Verify that the suspension spring setting is "H" (horizontal).
4. Affix the three adhesive dust covers from the kit over the transport holes on the bottom of the CD changer.
5. Mount the CD changer to the mounting bracket with four M4 X 6 machine screws.
6. Use a knife to cut out the perforated knock-out from inside the CD changer compartment left side.
7. Feed the CD changer power cable through the newly created opening and into the CD changer compartment.
8. Feed the fiber optic cable through the same opening into the CD changer compartment.
9. Connect the power and fiber optic cables to the back of the CD changer.
10. Carefully secure both cables in the CD changer bracket clip.
11. Slide the CD changer assembly completely to the left of the compartment until the bracket tab inserts into the compartment slot.
12. Secure the CD changer assembly at the right mounting tab with a screw.
13. Reinstall the radio in reverse order of removal.
