Unless you have the factory installed option of iPod interface, the dealer installed version will not only look different but will cost you significant money. it's a different way of connecting the iPod if it's the dealer installed kit. My understanding is that it will also connect and work with the iDrive system differently. I have the factory installed option and it pretty well integrated with iDrive. Sorry couldn't really tell you how the dealer version functions. Should work just fine though. Good luck. I also think it's worth it.
I have the 4.8i space grey with 214 wheels and it looks very similar to yours. However, yours looks stunning with the angle and the lights in the picture. great photo.
