Speed Limit Information requires an FSC code and cannot simply be coded "on" unfortunately. A retrofit kit for the US might be coming (it exists in Europe) but I don't have a timeline for this. It's odd that the Driver Assistance package on the 650 has it but the 640 does not.
I'm not sure I know what you mean by "live map". The main display always shows a live map, whether navigating or not. As for displaying this on the Info display, it is not possible.
M HUD is dependent upon the M instrument cluster. It has the software to drive the graphics on the HUD. Without this, it cannot be activated.
