It looks like I'll be keeping my M4 a lo-o-o-ong time, sticking with iD7. Well, I had my first BMW, a new 1994 E36 325iS coupe for 11 years until I traded it in for a 2005 E46 330iC coupe.
I have seen several demonstrations of iDrive 8 in this forum and on You Tube. That installation is as ugly as sin. Ford is doing something similar on the 2024 Mustang but at least they have a "analog" display mode that emulates a round speedometer and tachometer.
These freestanding curved screens whether from BMW, Ford, or other carmakers, suck.
