Notes on retrofitting telephone - AH82.70-P-0001-04B

Model 129, 168, 170, 202, 208, 210 

Retrofitting a telephone with D2B fiber optic cable technology is only recommended for vehicles in which D2B ring components are already present, e.g. Audio 30 radio.

Vehicles without these components should be retrofitted with a conventionally connected telephone supplied by Mercedes-Benz accessories department.

Vehicles with code 273 are preequipped for conventionally connected telephones supplied by Mercedes-Benz accessories department. Operation with the multi-function steering wheel is then not  possible.

On vehicles with multi-function steering wheel (telephone operation via buttons on steering wheel) it is recommended to retrofit a telephone with D2B fiber optic cable technology.

For this purpose it is necessary that a radio of the new Audio series or COMAND is installed.

A key pad is not present on Audio 30 APS or Audio 10 radio. It is therefore not possible to operate the telephone with the radio (see Owner's Manual).

Install portable cellular telephone at the center console.
