149 Navigation*
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 DVD
Navigation slot. The DVD Navigation slot is
located behind the display unit.
Open the display unit to get access to
the DVD Navigation slot as described in
“Starting an update” (
page 206).
Navigation DVD!
GPS (Global Positioning System) sig-
nals received make it possible to deter-
mine the current vehicle position.
Deviations from the actual position
may occur
if the reception of GPS signals is
disturbed e.g. in parking garages
and tunnels
if road conditions are bad
depending on the vehicle’s conditi-
on
i
There are two l buttons. One is on
the display unit. The other is located
