In terms of software support, the CIC's have it but will require a slight amount of coding to tell the CIC that the tuner is external.

Since your car is prewired, you could run an antenna extension wire from the CIC to the donor SDARS unit in the trunk.

But in all honesty, it's better just getting your internal tuner activated.
It is not pre-wired, Mike... that went away once the built-in tuners showed up. And his MY2012 CIC no longer supports dual Sirius setups even if he tries to retrofit the cabling required. His dealer is simply not reading the last 3 years of BMW documentation.
