4.
Now connect the black earth cable (GROUND) to the radio housing or the black cable
directly to a ground lead to the radio connection (mostly brown thick cable). Without a good
ground connection, the function of the adapter is not given.
5.
Now connect the red cable (ignition plus + 12V) to a sw 12V line. Since these are
usually no longer available behind the radio, you can keep the voltage for example from the
cigarette lighter or the air conditioner (measurement with multimeter necessary). Ignition on
= + 12V are on / Ignition off = 0V are on.
6.
Establish a Bluetooth connection by activating the Bluetooth search (pairing) and searching
for the Bluetooth device `` WM''. You should then set the volume to full volume on the
connected device.
7.
Before reinstalling the radio, test the function of the adapter. To do this, switch on the AUX
function via the AUDIO button on the radio.
For Info!
The AUX function must be selectable or unlocked!
If AUX is not displayed in the menu, it is necessary to unlock the AUX input at the dealer or in the
workshop, otherwise the adapter will not be recognized.
