I ordered my 2009 335i from dealer stock. It did not include the Sirius Radio option, however, so I opted to have it dealer installed prior to delivery. I took delivery on January 15 2009 and the dealer told me that the Sirius receivers were on backorder from the factory and that they would owe me the Sirius installation. I called the dealer over a month later and he told me that the receiver is still on backorder. Anyone have a similar experience???
