Do I have to plug the phone in?
Not necessarily. The connection is wireless; USB is there as an alternative.
Is it compatible with the BMW Seria 7 F01/F02 2009-2015?
Yes, the version in this category is built for the BMW Seria 7 F01/F02 2009-2015. Check the years and the system in the product title, then order.
Is the installation reversible?
Yes. It plugs into the LVDS connector, with no cuts in the loom. If you sell the car you take it out and everything is back to factory.
Does it replace the screen in my car?
No. The original screen stays where it is; the module simply feeds the CarPlay image to it. You keep the joystick and the steering wheel controls.
