Hello together, Since I want to use the so-called parking mode with the Dashcam, I have ordered an extra cable, which must be connected to mass, duration and ignition plus. Duration and ignition plus I took off from the radio after testing with multimeter. But camera does not work if I ignite. However, if I separate the duration plus first, and only connect again, when I have ignited, it works. Where is the error ? Can someone give a hint ?
