Default Seeking Help - '08 W-219; CLS 550 Sirius Radio Activation Probem

Seeking Help & Advice;

Car: 2008 CLS550 w/PII pkg + bluetooth adapter installed

Issue: Cannot seem to activate Sirius Satelitte Radio following multiple attempts with Sirius Product Tech group.


My new subscription is active and and the ESN no has been reconfrmed.

MB dealer confirmed the prior owner had activated the Sirius radio.

When I turn on the audio system and select "SAT" the radio (monitor) display reads "Not Subscribed", Call 800-XXX-Siri, ESN No. XXXXXXXXXX"

With audio system in SAT mode all I have is the screen above (pressing the "SERV" soft key does nothing. No other channel selection keys (i.e. tel. key pad or seek/scan have any affect)

With the audio system in SAT mode and with the above display showing, Sirius AUDIO can be heard through/from the speakers - appears to be the "preview channel" which may or may not be channel 184 (I have no way to tell) - but the signal is clear

All attempts to get the radio activated have been done outdoors in an open-sky environment

During these attemps the phone is off and bluetooth on the phone is disabled (I am not touching the bluetooth adater located in the center console glove box)

Sirius techs including product support claim the problem is on the MB end.

MB service techs claim that the problem is on the Sirius end

Me and my car are stuck in the middle...and I live 162 miles away from my closest MB dealer....

Any suggestions or experience that Forum members may have which resulted in fixing a similar problem in their car will be greatly appreciated..

Post Command System Reset

Following my earlier post/inquiry into fixing the problem I am having with activating the Sirius sat radio in my (new to me) 2008 CLS550.

Does using the "reset" in the Command System audio/telematics only rest the Command system to factory settings (i.e. loss of tel. directory / contacts list and previous Nav sys destinations)?

I am considering doing a Command system "reset" in an attempt to fix the problem I am having getting the sirius sat radio to activate.

Default Sirius Activation - Lesson Learned [08 CLS550]

Learned a lesson and want to share.

Purchased a '08 CLS550 CPO in Jan (2010). Upon purchase attempted to call in & activate Sirus Sat Radio subscription. The head unit would not activate, following numerous calls to Sirius, they referred me back to my dealer.

Dealer was friendly, accepted the service repair fix request, ended up chaning the comms module (mounted in trunk) afterwhich the Sirius would still not activate. Called them again and again and "Finally" got a Serious Sirius Tech on the phone wherein he advised that the module installed by my dealer (OE replacement for the 2008 CLS550, i.e. same part) is not capable of receiving the "Best of Sirius/XM Everything" service (subscription) package and can only accept the "basic Sirius" sub pkg. Once we downgraded the subscription the radio activated as its supposed to and the sat radio works fine.

Lesson Learned - if you purchase a CLS550 (at least as 2008 model), you cannot subscribe to the Best of Siruiis/XM Everything pkg and can only activate your sat radio using the Sirius basic pkg.
