Ill have to take my car apart in the back and see whats going on

There is nothing to take apart. Just lift out the trunk cover piece and see what connectors are back there. The pink one is for the SAT antenna if your car is 2007-2009(think?) At some point BMW started integrating the SAT tuner into the head unit, so the pink connector probably isn't back there in the newer models.

If the pink connector is there, you can just order the corresponding connector from ebay. RFsuppliers carries everything you need. Only problem is you need some Fakra crimpers for this, and they aren't cheap. I think I paid 40$ for mine?

Cut the antenna off the Sirius antenna cable that comes with your head unit, then splice the new Fakra connector in its place. Plug it into the pink connector in the trunk and your all set.

You can find tutorial videos on youtube for crimping Fakra connectors, it's very easy.
