Answer: The Z-E3215 MkII E>GO is able to process the BMW PDC CAN data, to fully implement the OPS function (“Optical Parking System”), so the optical park radar is supported by the device. Yet BMW vehicles of the E9X series come with acoustic PDC warning tones that originate from the factory radio. Therefore, after removal of the OE radio the Z-E3215 MkII does implement acoustic park radar signals via internal buzzer device (mono signal only). That means, acoustic PDC signals remain functional although the buzzer sound is not quite as pleasant, compared to the factory solution.
