2.4.8 Connectors, external interfaces
The WMI is connected with a permanent 12V and the CAN bus, various control signals from the
CAN bus control the WMI and thus bring it into different working modes. In terms of driving
readiness, the WMI represents an interface between the head unit (Can with 250kBaud) and a
standard mobile phone from the driver of the vehicle. To support NFC telematics functions
including identification and data transmission to the vehicle head unit, for example for data
exchange with NFC vCards.

To support these functions, there is a coupling antenna in WMI that fulfills the following functions:
• Interface to the GSM mobile phone via the coupling antenna
• Interface to the NFC enabled mobile phone via the internal NFC antenna
• Interface to the vehicle antenna via the GSM plug connection

2.6 TECHNICAL SETUP
Pre-Caution:
Before testing the unit make sure that the power supply system
doesn´t exceed a voltage over 12V to avoid short-circuit.
Connect the wireless charger with the power supply system
by using the red and black cables (the yellow cable is
irrelevant).
Connect the wireless charger with the USB Can
adapter via the green/yellow cable.
Connect the USB Can adapter with a computer.
Turn on the power supply system.
Note: The LEDs of the CAN-Adapter are going
on and off several times. This process is uncritical
