Hello everyone, in July 2020 I received B1M from Aliexpress and then I installed following the attached instructions for 4 trips everything went well then the problems started, 12v power supply first discharged battery then it stops working I order another one and then I mount it in April 2021 the recordings are not regular and the storage stops the files cannot be seen in May the front camera no longer works I order it and then I mount it, then it does not record anymore and after several tests I come to the conclusion that: it works with usb power supply to the condition of disconnecting the remote control and gps, the problem remains on the BMW that the TPMS does not work properly due to interference, but all this is enough for me to think about taking everything apart.
