There are two changers which can use the D2B fiber optic loop to connect to the factory headunit. One is the factory/dealer Alpine changer, and the other is the Becker 2662 Silverstone. The Silverstone is bigger unit than the Alpine. I don''t know if the changer goes in the glovebox in and E like it does in a C, but if it does the Becker may not fit.
The Alpine changer can be purchase from Auto Class for about $400. The installation kit is about $100.
I have the same model, but it is an imported from Germany (e240 Classic 2002) it comes with the original Mercedes Car Stereo. I went to am technician that installed a normal cable (not fiber) from the car stereo to the back of the car. Then he installed a CD-CHANGER + CD magazine (Signed with Mercedes, Japanese Made, but I have not checked the brand). Once he tried to test the magazine through the Car stereo, it never responds. He tried to use another stereo, and it also never worked. Then he claimed that the car stereo needs an adjustment from inside by an electronic technician to allow it to accept CD-CHANGER. I refuse that theory and ask him to remove it. I think that the CD-CHANGER he installed is not compatible. And I suspect that the cable wiring he installed has some wrong configuration.
I've few questions:
1- Is the normal cable is enough or do I need to use a fiber cable? And what are the options?
2- Is my car stereo not compatible with that CD-CHANGER?
3- Is the technician says the right things?
4- I ask the technician to keep the cable, will it be useful for me to install another compatible CD-CHANGER (you suggested).
Sorry, I don't check the E class forum too often. I usually leave that to ajcrowe and bigbenz man.
To the best of my knowledge, it is impossible to connect a cd changer with copper wire. Your car which was intended for the German market is somewhat different. It hs a different headunit. The headunit provided for cars sold in the US is not available in Europe. On the other hand, Europeans have several choices in headunits with cd player or cassette player and even a single DIN opening navigation system, the Becker Audio 30 APS. Also, all US cars come prewired for the cd changer, but the Euro cars do not.
I don't know as much about E's as I do C's but I am certain that only the two cd changers from my first post can be used in any MB built since 1999. They require the use of the D2B fiber optics ring. The change must be placed in the proper order in the ring. I don't remember what it is, but I could probably find if you need it. Eventually on of the microprocessor must be configured for the cd changer. Otherwise fault codes will accumulate until the changers stops functioning.
I ask ajcrowe or bigbenzman to move this thread to the Audio forum because I check that more often. If anyone with better knowledge of the E has different or better information, please share it with us.
Correct CD changer should be plug compatiable. Only 2 wire connectors to connect(fiber optic). Dealer wants $1100 for factory CD changer so I bought one in ebay, a MBZ OEM CD changer for $245 plus shipping. My E320 is disigned for CD changer mount in the rear trunk(Left hand side).
I pulled 2 wired connectors from side panel and just plugged in. No cut and splicing what-so-ever. Off it went, no problems. Works excellent. I did buy mounting bracket for $24.
