Date 09-22-2009

Validity models 171, 230, 164, 251, 169, 245, 211, 219 and CLC 203 with SA code 512, 527 or 528 and SA code 809 or 800 (NTG2.5

Model 463 with SA code EU1

Reason for change Title, complaint and remedy revised/Supercedes DTB S-B-82.85/679

Reason for block

Complaint:

Radio stations are displayed twice in the COMAND unit (A40/3). Radio stations saved by the customer are sporadically overwritten by other radio

stations.

The COMAND unit sporadically performs a reset while driving. The map in the navigation function freezes....

Cause:

Software error in COMAND head unit (A40/3).

Remedy:

With telematics CD released with DAS 06/09 (A 171 827 40 59), the software of the COMAND unit must be updated to version 02/09.-->We

strongly recommend using DAS 07/09 and later with all of the patches installed.

NOTE:

If the software release of the COMAND unit (A40/3) is 08.08, it is necessary to update the map data. DAS automatically checks and displays the

necessity of updating the map data.

The software update also remedies the following fault profiles:

Bluetooth connection to head unit terminates prematurely or calls are aborted and reconnected

Systems:

- System starts until star appears, performs a reset and then restarts normally

- Cyclic resets with system starting only until star appears

- Random resets during navigation mode

Radio:

- Stations change at random

- The display station name does not match the station being received

- Preset list is overwritten

Navigation:

- Improved TMC behavior, improved route options (avoiding toll roads)

- Improved route options (shortest/quickest/dynamic route)

- Navigation cannot compute a route (automatic continuation of route). The second time the direction is changed, the route is not recalculated. The

blue line disappears. The system announces: :The route cannot b Navigation map freezes e computed - follow the direction arrows". Head unit shows "No route"-

New functions are implemented as of software release 02/09
