Reason for block
Complaint:
The COMAND unit (A40/3) can no longer be operated (freezes) when changing to the telephone menu using the "TEL" key.
Cause:
Software error in the COMAND unit (A40/3). The COMAND unit (A40/3) has saved 21 entries in the call log. However, the software can only
manage 20 entries.
Remedy:
Update the entire telematics ring using DAS version 01/10 or newer and Telematics CD A171 827 41 59 (or newer). The software of the COMAND
unit (A40/3) must be updated to version 29/09
Note:
If the software release of the COMAND unit (A40/3) is 08/08, it is absolutely necessary to update the map data using patch DVD A230 827 02 59 or
newer as prompted by DAS. DAS automatically checks and displays the necessity of updating the map data.
Do NOT perform the map update as a "customer upgrade" or your claim will be denied
If DAS prompts you to use a map update, you must complete this step otherwise the head unit may not function correctly
The software update also remedies the following errors:
- Uncommanded overwriting of the FM station memory list is prevented
- HU freezes in telephone application as soon as more than 20 entries are saved in the call log
- Audio application is audible at the start of a phone call
Notes about software updates:
You MUST complete the software update for the entire Telematics Ring. It is critical that you follow DAS prompts, search for new software and
carry out the entire update process for all of the telematics components which DAS has found new software for. Software updates are done as a
"package/profile". Failure to complete the update process for these components will result in operation errors.
Checking for new software MUST always be carried out after a component replacement. Use the "control unit programming" step to check for any
new software and perform the necessary updates as guided by DAS. Additionally:
^ DO NOT Interrupt the update process
^ All telematics components software must be updated together as guided by DAS
^ You must check for new software - if after diagnostics- a component replacement is deemed necessary, if a new software is found by DAS you
must complete the update for all components found

^ Always use a battery charger throughout the entire update process
^ Always complete the SCN coding
^ Where applicable (during parts replacement after diagnostics), an initial start up must be performed
Failure to adhere to the above process may cause the head unit and telematics ring to be faulty, any parts replacement claims as a result will be
denied
