Installation 

To install the interface, first switch off the ignition and disconnect the vehicle’s battery. 

Please read the owner`s manual of the car, regarding the battery`s disconnection! If 
required, enable the car`s Sleep-mode (hibernation mode)  
In case the sleep-mode does not succeed, the disconnection of the battery can be done 
with a resistor lead. If the necessary stabilized power supply for the interface is not taken 
directly from the battery, the chosen connection has to be checked for being constantly 
stabile. The interface needs a permanent 12V source!
