I'm thinking of adding the snap in adaptor for iPhone to my new car.
I should have ordered it with it, but I didn't.

I have the iPod "kit" which just doesn't work well as far as charging goes. Even with the new wire, it's difficult to get the iPhone to charge.

Anyway the parts guy tells me that smart phone interation may already be in my car X5 but can't seem to; or maybe just won't tell me how I can tell if it is.

Is there a way I can tell if it's already installed;?or I'd the wiring is there for a DIY project?
