Important notes
COMAND calculates the route with the
help of data that is stored on the navigati-
on DVD.
Only use Mercedes-Benz navigation DVDs.
Using other navigation DVDs or CDs will
cause malfunctions and/or damage.
Because of changes in local traffic patterns
(e.g. road works) and/or incomplete data,
errors in calculation may occur.
As a result, the recommended route may
deviate from the ideal route. The data
stored on the DVD only reflects local con-
ditions at the time of DVD production. DVD
maps do not cover all areas nor all routes
within an area. Loading/ejecting a DVD
DVDs are loaded and ejected at the
navigation computer. The navigation
computer is located on the left side in the
trunk.
