I ordered the modules for roughly $250 and paid $125 for the install. Retail was $300 on the modules, so I would expect to pay $400-$500 so to buy and have installed the Sirius modules on our cars if they don't come with it.
When my wife (separated) totalled her '10 128i, she found a 2012 replacement with 350 miles on it for a steal out of state (someone won it a casino and couldn't afford to pay income tax on it) but it was missing Sirius. Before she bought it she gave the VIN to a CA at one of the local BMW dealers and he looked it up and confirmed that it was "Sirius ready" and he told her it would be $400 for them to set it up for her. Not sure if this required any hardware or just a software update. I'll ask her for details tomorrow, but I'm guessing they will be able to do that same thing with the '13 F30s.
