24DrivesCD playerIntroductionThe navigation system is equipped with an internal CD player. The CD player 
can be used to play navigation, audio or MP3 CDs.
Audio/MP3 CDs inserted into the drive are played using the CD function 
⇒ page 44. If your vehicle is equipped with a CD changer*, you can select the 
inserted audio CD via the  CD position. The CDs in the CD changer take up 
positions  CD1 to CD6 .
A navigation CD is selected using the NAV function  ⇒page 85.
MP3 files must meet the following specifications:
The playing time displayed may differ from the actual time in MP3 files with a 
variable bit rate. As a rule, the MP3 music files are copyright-protected under the applicable 
international and national laws. In some countries the making of copies is not 
permitted, not even for personal use, without prior authorisation by the 
rightful owners. These restrictions do not apply if you are the rightful owner 
of these rights (e.g. in the case of your own compositions or recordings) or if 
the rightful owner has given you permission to use these rights.
Note
•You can obtain navigation CDs from your dealer. Your dealer will also be 
able to provide information on updates which are available for the CDs.•Please observe the notes for handling CDs  ⇒page 25.•In view of the variety of CD-Rs and CD-RWs and the difference in memory 
capacities, the quality of the MP3 function may vary in the case of some 
memory media.

NoteYou do not receive any information about the meaning of road signs!How does the navigation system work?
The navigation system works with the help of satellites (GPS).Route information and satellite signals are used to pinpoint the current 
vehicle position. GPS satellites send the necessary signals required by the 
system (GPS stands for “Global Positioning System”).
The information is transmitted to the navigation system and compared with 
the information stored in the navigation CD map database. This way, the 
route guidance can be accurately calculated.
The navigation CD must be in the CD drive to calculate the route  ⇒page 24. 
Once the calculation is complete, you can remove the navigation CD and play 
audio or MP3 CDs in the internal drive unit. The data required for navigation 
is stored in the navigation system. Where the navigation system requires 
more data (e.g. if the route is modified), the system will ask you to insert the 
navigation CD.
Navigation operations are limited if the navigation CD is not inserted. Some 
functions, such as route modification, are “greyed out” and cannot be 
selected.
The navigation system improves the route during the trip. The route initially 
calculated may differ to the route actually taken.
The navigation instructions can be given in 9 languages (English, German, 
Spanish, French, Italian, Portuguese, Dutch, Swedish and Czech). The 
language can be selected using the  menu language function in the setup 
menu  ⇒page 116.
Note
•Snow or other obstructions on the GPS aerial or interference caused by 
trees or large buildings could affect the reception of the satellite signals and 
make positioning difficult. GPS reception can also be adversely affected by 
the deactivation or malfunction of several satellites.•Street and town names can change, therefore the names stored on the CD 
can in some cases be different from the names that have since been changed.•You can obtain navigation CDs from your dealer. Your dealer will also be 
able to provide information on updates which are available for the CDs.Navigation route guidanceRoute guidance assistance is given both visually and acoustically:•by voice guidance•by the display in the dash panel  ⇒fig. 93

⇒page 86, fig. 93 .
The navigation display in the dash panel display is shown during a route 
guidance even when you select other functions in the navigation system (e.g. 
radio or CD). When you operate other functions of the dash panel display via 
the multi-function steering wheel, the navigation display will temporarily be 
replaced by the function you want to use.
