I brought 70mai with the special power line from provider, connect power to 24 hours power line.

However, Parking surveillance works doesn't work after I turn off my car (BMW).

Pls help.

    The same here, but I suppose that I find the solution.
    I also connect the external power, BUT NOT at the positive pole of the fuses!!!

    Try to connect the cables at the positives poles of the fuses.
