Actually, they don't know what the fix is yet nor do they have a time estimate. They're telling people 2 days because they have no grasp of the resolution. When it happened this morning I called in and was told it would be back on "shortly" - that they had already fixed it and they only needed to send another activation hit to my unit. That was after waiting on hold for 35 minutes to talk to somebody. This evening when it was still not working, I called in again. Only 20 minutes on hold that time. This time they said that they had tried to fix it, which is what then caused the Kia outage (initially it was only MB). They then said I should wait 2 days before calling back in. They indicated that we could be credited for days lost (no financial compensation) but that would require calling back in AGAIN (and waiting on hold again) after the system came back (whenever that is).
This was all an ill-planned marketing campaign to deliver XM content to Sirius users free for 2 weeks as a trial, in hopes that we'd pony up yet more cash to keep that content. Instead, they've killed our service. They won't roll back, because that would take the "campaign" away from all the non-MB and Non-Kia subscribers that they've advertised to. There is zero information posted on Sirius about this, and no assistance whatsoever to customers other than expecting them all to call into the understaffed customer service numbers and wait on hold forever. Simply another nail in the coffin lid of Sirius as they circle the drain.
