iPhone Integration BMW 740 iL

Dear Bimmer Owners,

I am upgrading my BMW 525i with 740 iL and would like to know the following as I was unable to get this information on the web

1. Is the iPod / iPhone cable which I was using with 525i will be compatible or I have to buy another cable?
2. Will I be able to see the album cover art on the display?
3. Is Siri can be activated through one of the buttons on the steering wheel?
4. Can I use the iPhone cable with the snap-in adapter?

Your feedback in this regard will be highly appreciated.

Thanks and Regards.

Depends on what options you get with the car. I had 6NR retrofitted and I get album cover art. You can also use the original iphone cable. I've yet to find a way to enable Siri while driving though.
