Mine does. Its dashboard shows fuel level and a bunch of other things and I can bring up a speedometer/rpm app.

I believe the connection exists because the steering wheel buttons/iDrive talk to the original head unit over CAN.

That’s wild, I’ve never run across a head unit that had me connect OBD2. I think I would just ignore that bit of the install instructions.

This is available on standard OBD-II. Maybe, it is accessible over CAN?

    My OBD-II connector has CAN-C (500kbit) and CAN-B (50kbit) - I use CAN-B primarily because I can control windows, doors, etc + get the speed & rpm.
