I ordered my 2009 335i sedan last July and took delivery in late last August. My car has premium, cold weather and sport packages along with navigation and upgraded sound system. I did not order the car with satellite radio (my mistake) and I am now interested in adding that option to the car. From the factory the cost was arounf $600. I called the local dealer and they quoted me a price of $1,800 which includes a one year subscription. That price seems like robbery! Does this quote sound correct? I clearly underestimated this but I thought the upgrade to add satellite radio was likely a simple modification and that the car is likely already prewired for the satelite radio with exception to some additional module that may need to be installed to allow the radio to receive satellite radio signals. Clearly the best answer would have been to order it when I ordered the car last year Anyone else have any thoughts on this? For $1,800 I can clearly learn to do without it and listed to normal radio or my iPod connected to the car.
