Notes on map CDs
The navigation system is based on a C-IQ database, which is stored on a CD in en-
crypted format. The CD contains map data for navigation as well as travel and traffic
information (TMC) for dynamic route planning. You can customise your navigation
package by enabling specific products.
More information can be found under “C-IQ - Intelligent Content On Demand”, see
page 53.
Handling CDs
Avoid leaving fingerprints on the CD when remov-
ing it.
Always store map and audio CDs in their protec-
tive covers.
Always ensure that CDs are clean and dry before
inserting.
Protect CDs from heat and direct sunlight.
Cleaning the unit
Do not clean using cleaning fluid, alcohol or other solvents. Use only a damp cloth.
