AW: Zenec units include a low-voltage protection to avoid undersupply for certain integrated circuits (ICs) that may not work properly without correct and steady supply voltage. Please consult your car service point or car garage to review your car´s battery and wiring.
The cause of device reboots is therefore to be found in the on-board power supply network, which falls briefly below about 10.5 volts during engine start-up.
Please consult your car dealer and let check the battery and the cable connections.
