Reason for block
Complaint:
Head unit displays "device unavailable" when user switches to satellite radio (SDAR) with a possible Battery current draw.
Cause:
Under-voltage condition with the vehicle itself can cause the satellite radio to go into bypass. The satellite radio (SDAR) operation can be recovered
by a hard-reset to the receiver; however, this condition may reoccur.
Remedy:
Use DAS version 01/10 or newer and telematics CD # 171 827 41 59 ES2:0001 (or newer) to update the relevant telematics components.
Before you start the update process:
Before you start the actual Control unit programming process, it is highly recommended to check all available software and print this sheet showing
which component is getting an update along with current and new software. This sheet is useful to make sure all found updates are successfully
completed.
Software updates in general: (Read this first)
Always use the latest DAS version along with all of the patches. DAS patches (AddOns) can be found in the Aftersales XENTRY portal, one of the
links you can use is this:
https://aftersales.i.daimler.com/sdupdate/
^ You MUST update all of the components which DAS has found newer software for, otherwise the autio video system will not function normally.
^ Under no condition can a component update be skipped unless DAS clearly indicates " no newer software found"... for that component. Every
component MUST be flashed.
^ Always note the telematics update CD referenced by DAS as it may be newer than the latest CD available to you.
^ Do not use an older telematics CDs (even if you know it may belong to that specific telematics generation) than what DAS displays for you during
the control unit programming process, if you do not have the prompted CD, do NOT attempt to flash.
^ Update process normally starts out with the ring master (head unit) and continues through the rest of the telematics ring, but not necessarily. It is
possible that the process does not start with the head unit, in this case select the one of the components on the update list and start with it then
continue updating the remainder of the ring.
^ Make sure the head unit's DVD/CD drive is empty before inserting the telematics CD. The head unit CANNOT have any other CD except for the
telematics update CD/DVD during the update process, you should always use slot #1 in the changer as this is the first slot DAS looks for a CD in.
^ You must connect DAS and start the control unit update process and WAIT for the DAS prompts to advise you to insert the telematics CD. Please

do NOT insert the telematics CD into the head unit first, then start a DAS session, this may cause the telematics CD to keep ejecting.
^ You must reset the optical ring after software update and allow CAN and MOST asleep.
Software update process:
1. Connect a battery charger and DAS. DAS must be connected at all times and throughout the update process. If DAS is disconnected during the
update, the flash will interrupt and may corrupt the telematics system and render the head unit's operation irrecoverable even if you perform a
hard-reset on the head unit so it is critical that you have a stable power supply connected at all times.
Before you start the actual control unit programming process, it is highly recommended to check all available software and print this sheet showing
components that are going to get the update along with current and new software. This sheet is useful to make sure all found updates are successfully
completed.
2. Start the telematics update by selecting COMAND > control unit adaptations > control module programming, follow DAS prompts.
While DAS is searching the telematics CD for the proper application software for Head unit such as DVD mechanism, bluetooth, navigation, voice
control or for other telematics components such as sound amplifier, UCI, satellite radio / combi tuner it may display the message " Software missing
". This is normal. Do NOT interrupt or restart the update process, other wise the head unit can get corrupted.
Software update progress bar may not indicate the elapsed time/time remaining for the update. Even if the progress bar does not seem to be
changing, the update process is taking place in the background. Please be patient, do not interrupt the process and allow DAS to continue through
until the process is complete and you are prompted by DAS to eject the telematics CD from the head unit
3. During the update, the telematics system will reset (restart) a few times, this is normal. If DAS could not start out by updating the head unit first,
then select another component on the ring --> start updating it --> then manually select all of the components until you have completed the software
update for the entire telematics ring.
4. After update is complete and SCN coding is carried out, delete DTCs and reset the optical ring --> allow CAN and MOST asleep.
5. Start the head unit and check for correct functionality.
Telematics components bypass notes:
Telematics components are specified to go into bypass (self protection) when sensing an under-voltage condition of 10.6 V or lower. Due to a
software error in the satellite radio, it is more susceptible to going into bypass before any other telematics components even if the voltage supply to
the receiver is over the low voltage threshold. As a result a "device unavailable" message is displayed on the head unit.
