Sirius told me the same thing.. No "Best of XM" on my 08 535xi.. I have no idea why it wouldn't work, they're just rebroadcasting the 6 or so XM channels on empty Sirius channels.

 

I am having the same problem on my 08 550i. The sirius website allows me to add the best of xm package but I still can't recieve any xm channels. I have spoken to sirius and received no good answer. I did read on another forum that if you are on the 1 year promotional package you can't recieve best of xm until the promotion expires. Makes no sense to me. Anyone else heard this?

Thanks.

 

I heard it's the same on the XM side...

Someone I know with an Acura that just renewed his subscription for a year (to get a discount) can't change to the "best of Sirius" package until after his current subscription expires...
