I did not connect ODB2. The HU I got puts itself as a passthrough to the stock BMW HU (which you still need to be able to use, you switch the screen to its output by holding down a button), and that connector includes CAN.
There are numerous reasons the HU needs CAN, for example to get the steering wheel angle to be able to draw the guides over the backup camera feed. Or to switch to the backup camera feed when you put the car in reverse.
