Before you start…
Please take a moment and read this manual before you install the M3-ATX in your
vehicle. Often times, rushing into installing the unit can result in serious damage
to your M3-ATX board, computer and probably your car’s electrical system. Always
double check the polarity of your wires with a voltmeter.
Avoid using the cigarette plug as a power source, often times the contacts are not
capable of delivering high current to your PC.
