I have a 2000 E320. It was equiped with a startac phone, and I have not changed over yet, but I have bought a Mikbox and a Verizon v710 phone. My problem was that the whole fibre optic system stopped working about 16 months ago. I pulled the phone handle on the steering column and nothing. The CDC kept saying "no cd changer" etc, etc. Yesterday I pulled the car out of the garage and we heard a noise like the serpentine belt squeeking, then it stopped after about 2 minutes. When my wife brought the car back that night she said there was a strange message on the radio, and that the squeek started again when she started it. I walked down to the bottom of the driveway to drive the car into the garage (too much ice for her), and I pulled the phone lever and it started going thru all the numbers I had stored in it! I pushed the CD button and the CD started playing! I do not have the old startac or my new phone connected yet, so I do not know if they would also work. So----after all that story I have no idea what happened, but everything works again as if by magic. Anybody have any idea what is going on??
