Answer 1

Hi

Please cross check your FMB920 wiring in the vehicle, The VCC (Red wire) of the device should connect to the voltage line directly coming from the battery.

Even after the key removed from the vehicle, the device should get the power supply voltage.

Probably in your case, the wire you connected the VCC will get voltage after the ignition ON.

Thanks in advance,
