Hmm, I also have a BMW with wireless CarPlay, and observe:
- notifications show up on screen without sound (have the phone set to silent, so that's what I expect
). Tapping a notification does read it out aloud.
- I don't notice a difference when wireless charging or charging through cable connected to the USB-C port under the central armrest (which can be used with other phones and shows up as a USB connected device)
- the selection cursor remembers where I left it (rotate the iDrive controller to move it around). For me I have it at the upper lower corner where you would active the 'home (?)' view (map on the left, connection/music/upcoming calendar event on the right).
- I'm always using the North = Up -> no need to zoom out... ;-)
