Issues I am aware of on R59:
- Still some bluetooth issues.
- CarPlay problems with fails to connect if connected too soon, disconnects, forgets car is RHD, plus A/C dropdown no longer works from CarPlay screen.
- Some people still report radio problems.
- Wifi hotspot has DNS bug, stopping some from using it.
- Reports that some of the new shortcuts on the right menu pull down don't work.
R63 might fix some, I doubt all.
There's also minor feature stuff like the infotainment screen can't change the lighting according to levels mentioned by the light sensor, which many other cars do have.
