In addition to the Audio 30 radio, you'll also need to install the wakeup line, power and ground line from the radio back to the changer, plus the D2B fiber optics line itself. The harness for the radio itself will no doubt need to be reconfigured, and a way to connect the radio to the diagnostic port to allow reconfiguration of the internal parameters of the radio to reflect the presence of the changer. Sounds like way more work than it's worth, i would consider finding the appropriate changer for the existing radio.
It may not even be possible to reconfigure the radio due to the difference in equipment. The computer likely wouldn't be looking for the sound system if you entered in the proper model (1996), and if you enter 98 or 99, the proper year for the radio, the other lines would be absent, but you may be able to try going only into the sound system at it may pull it up.

Your radio should have cd capabilities, and it is a simple "plug and play" model. On the upper right corner there are 4 buttons which are labeled "AM-FM", "WB" (for weather band), "TAPE", and "CD".
I would greatly discourage proceeding with this installation, there are too many unknowns. I believe the radio will fit in the dash OK, but the electrical harness will be very different. The CD changer receives power, ground, and a wakeup signal from the radio, this will all have to be in place. Also the radio needs to be version coded with the Mercedes computer in a MB shop. There are diagnostic lines which must run to the diagnostic connector in order to version code the radio, these wires must also be installed. You could go through an awful lot of work for nothing, I would discourage doing it, find the proper CD changer instead and use the original radio.

Hi ror,
The head unit you have is a CM2299 and the changer is a CM3198. These two units will work fine together provided you connect the wires to control the changer properly. I have attached a photo that identifies the wire connections needed to make it work. No programing should be needed to work in the car this way. You need to provide the changer with a Keyed 12volts and a Ground wire where ever you put it. You will need to run a single wire from the radio to the changer for the Wake Up line. And of course, a dual Fiber Optic cable. Then connect it to the Fiber Optic loop which can be found at the Telephone transceiver in the trunk area. If you have any problems with the car not seeing it you will need to unplug the 3 pin plug on the CD changer, Cycle the ignition on then off, plug the 3pin plug back in and you should be able to use the changer. If you have any problems or questions please contact me via my Web Site: www.lajollaaudiorepair.com

The cd changer will not continue to operate reliably unless the radio is version coded to reflect the presence of the changer. The radio can not be version coded unless it is connected to the diagnostic connector.

ror,

I have tested these two units on my bench and they will work if you connect the Wake Up wire exactly where I show in the picture. You will need a Keyed 12volt line routed to the changer and a Fiber Optic cable from the radio to the Changer location, which will be expensive. The Fiber Optic cable will be a dealer item only. The length will all depend on where you mount the changer. If you need any more help then contact me via my Web Site: www.lajollaaudiorepair.com
