Sirius Since New Channels
I called them today and asked for "Technical Support Escalation" and was put through to a tech, who confirmed that they know of problems with Mercedes vehicles matching the symptoms I have. The tech placed an individual escalation on both of my Mercedes radios based on their ESN. She also said they are working on fixing the problem but have no ETA for the repair and cannot confirm at this time that the fix will not involve some change to the car!
If any of you are having these symptoms, I suggest calling Sirius and having your ESN number escalated for attention within the Tech Support department.
