I just finished modernizing my 2006 650 with upgraded electronics. Replaced the CCC with a CIC, new screen, new iDrive controller, backup camera and MMI that provides CarPlay. Purchased the kit from BimmerTech. Very pleased with the end result. Makes the car feel almost new again.
Yep! You have to tap a hot wire. I think I used the emergency flashers and run it to the ACC controls. Seems like there was anther change but I don't remember now. A quick search will get you a DIY to update to IHK2
