context_page_description: Cockpit Management and Data system - COMAND for short - acts as a combined command and control centre for all audio, telematics and telecommunications functions on Mercedes-Benz vehicles and includes a dedicated flat display screen. In addition to the GPS navigation system and general processing and control logic, COMAND includes components such as an address book, telephone, radio and in many cases a CD/DVD drive. It is connected to other devices such as CD/DVD changers, sound system and surround sound amplifier, TV receiver and the optional Linguatronic voice control system via an optical fibre network. The first generations of COMAND used the D2B optical network standard whereas later models are based on MOST.
  A key feature of all COMAND systems is to provide deep integration between the various functions such as multimedia, navigation and telephony and to also allow multiple presentation and control facilities. An example of functional integration is where other audio sources can be muted when a phone call comes in or when navigation guidance is being given.
context_section_description: Somewhat confusingly, COMAND 2.5 (not to be confused with the much later COMAND-APS NTG2.5) actually refers to the first generation of COMAND systems, introduced on the W220. The "2.5" label seems to refer to the fact that the main COMAND unit for this first generation had a height of 2.5 DIN. This COMAND system had a cassette drive, a built-in CD drive for the navigation map discs, an FM/AM radio tuner, a 4-channel amplifier and external connectors to other systems. The European models used Tele Atlas map discs (CD). Towards the end of 1999, the system was upgraded to use the improved DX type navigation discs. COMAND 2.5 uses a D2B optical bus for connection to the external CD changer, the telephone system, the optional Bose surround sound system and the optional Linguatronic voice control system. The COMAND 2.5 unit was made by Bosch.
  COMAND 2.5 was an option on almost all models and denoted by Mercedes-Benz option code 352.
