Hi
I am new here and also new to MB.

Here is my situation.

I purchased a cd changer on ebay. I could not find one of the plugs that connects to the cd changer.

I have searched most of the posts relating to the installation of the cd changer in a E320 wagon. I searched the rear passenger wheel well.

I finally found the missing connector for the player...it was plugged into something else next to the cd changer location. I unplugged it and plugged it into the cd changer and it works great.
My question is.....what did I unplug it from? The phone unit? Do I need a splitter or another jack now for both?

I dont want to fry anything.....

Thank you for any help in advance....
