3.1.￿Combox
The￿Combox￿control￿unit￿is￿located￿in￿a￿housing￿that￿has￿been￿designed￿for￿installation￿without￿a￿hold-
er.￿Thus￿in￿certain￿vehicles,￿the￿Combox￿is￿installed￿without￿an￿additional￿sheet￿metal￿holder.
In￿the￿event￿of￿a￿collision,￿however,￿the￿impact￿energy￿is￿transmitted￿directly￿to￿the￿control￿unit￿when
there￿is￿no￿sheet￿metal￿holder.￿Therefore￿the￿Combox￿control￿unit￿must￿be￿checked￿for￿external￿dam-
age￿after￿the￿vehicle￿has￿been￿in￿a￿collision.

3.1.1.￿Versions
Although￿the￿Combox￿is￿only￿available￿in￿combination￿with￿the￿BMW￿Assist￿(option￿639),￿different￿ver-
sions￿of￿the￿control￿unit￿are￿used￿depending￿on￿the￿vehicle's￿electrical￿system￿and￿optional￿equipment.
Therefore,￿there￿are￿currently￿four￿versions￿of￿the￿Combox:
Vehicle￿electrical￿system￿BN2000￿(L2￿[E8x,￿E9x]￿and￿L4￿[E7x]￿as￿of￿09/2010)

Combox￿with￿telematics￿and￿GPS￿receiver￿(With￿BMW￿Assist￿and￿Navigation)

3.1.2.￿Interfaces￿and￿components
To￿make￿it￿easier￿to￿tell￿them￿apart,￿the￿system￿connector￿is￿white￿for￿the￿vehicle￿electrical￿system
BN2020￿and￿black￿for￿the￿vehicle￿electrical￿system￿BN2000.￿The￿Combox￿is￿connected￿in￿the￿L2
and￿L4￿to￿the￿K-CAN￿and￿in￿the￿L6￿to￿the￿K-CAN2.￿Because￿the￿K-CAN￿and￿K-CAN2￿have￿different
speeds,￿the￿color-coding￿was￿implemented￿to￿prevent￿them￿from￿being￿mixed￿up.
