MOST Direct Access Port

Because the vehicle is based on a 2000BN vehicle and is equipped with a MOST-bus, MOST direct access port is also installed in the E89. The MOST direct access port is located on the left in the footwell.

The two connected plugs must be taken from the common connector (A). The two plugs are then connected together (B). The integrated communication optical module ICOM can now be connected in the usual way to the joined plug.
