Which can-bus system do i have please?
Hi guys
I have just got into mb and am the proud owner of 2000 model S 320.
Im thinking of replacing the audio 10 CC unit with one of the latest type seen on ebay. I need to know if the can-bus system will work with therefore can anyone shed any light on which system i have please?
Any help will be greatly appreciated.

Bigsteve99,
You either know a great deal about your car's electronics, and are able to connect the system you have in mind to the CAN-B system; or you are asking about the fiber optics bus, D2B or MOST.
You can read about the Mercedes CAN buses (CAN-B, body, and CAN-C, engine/chassis) at http://www.mercedestechstore.com/pdf...2010-28-02.pdf - I do know that when some folks in the U.S. replace their audio systems with 3rd party equipment, they use interface controllers (such as those from Pac-Audio) to maintain steering wheel controls over the audio system. Such devices are CAN-B tie-ins.
If you are asking about the fiber optics bus, to which most audio components are connected, it is a different story. You didn't say which year your car is; you can see the fiber optics types and diagrams for U.S. models in the phone bulletins at http://home.earthlink.net/~phdwebsit..._bulletins.htm - but I am not certain that the type of bus will be the same from year to year in European models.
There is a bit more discussion at post #7, http://www.benzworld.org/forums/audi...ation-kit.html
You can verify which bus you have by looking at the connectors; see http://www.mercedestechstore.com/pdf...2003-09-04.pdf for a good treatise on D2B, plus a photo of a D2B connector. Also, post #4 at http://www.mbca.org/forum/1-how-guid...-and-bluetooth describes the 2 types of connectors and has photos.
Installing a 3rd party head unit or nav/DVD system generally means removing everything on the fiber optic loop - nav, phone, voice control, CDC, amp, etc - and replacing it. Many of the 3rd party systems contain the capabilities, but may require additional amplifiers and sound processors to get the sound you want. In addition, if you have Bose speakers, they are 2-Ohm - while they can be used with some non-Bose amps, there are certain considerations in using a 2-ohm speaker vice the industry standard 4-Ohm. But that has been written up several times before, so I'll let you search the forum for that.
