COMAND(R) - Various Radio Display/Navigation Problems COMAND: RADIO STATIONS ARE SHOWN TWICE IN THE DISPLAY, STORED STATIONS ARE OVERWRITTEN, SEVERAL SYSTEM ERRORS AND NAVIGATION PROBLEMS Topic Number LI82.85-P-048031 Version 1 Design Group 82.85 Navigation and communication systems (CNS, ICS, COMAND, FleetBoard) 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: Page 136 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 be computed - follow the direction arrows". Head unit Navigation map freezes shows "No route"- New functions are implemented as of software release 02/09
- Static guide lines in reversing camera image for model series 164/251
- Implementation of Service call
- Automatic reading of Traffic Message warning messages on the route
- Audio volume reduction for navigation announcements (activatable)
- Level adjustment for AUX signal
- Support for SD cards greater then 2GB
- RDS Radio Text and Radio Text plus
- Blower speed reduction when voice control is active
Software update notes: ^ Battery charger must be connected throughout the update process ^ The head unit may display the message "SOFTWARE MISSING" or may reset a few times during the entire update process: This is NORMAL! do NOT interrupt the update process ^ Do not disconnect XENTRY/DAS even if you see the software update process bar not moving ^ Do not interrupt the update process unless guided by XENTRY DAS Page 137 Symptoms Work units Page 138 Page 139 Validity
