Looks like it's going to work out great for you! I have the same HU in my '11. I absolutely love it. I retained SYNC, but never even use it. The HU is MUCH better.
The only complaint I have is the prices you paid for some of the stuff. You paid a little more on the HU and on the door speakers than you could have compared to many online retailers. Then again you said you got the ipod cable and traffic tuner, so that's probably the difference in price. I don't know how much everything else normaly costs so I couldn't tell you about the rest. But other than that it should be awesome. I know you'll love the x930bt.
