Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Audio Data Control Line
The audio data of the snapped in cradle adapter for the mobile phone is controlled by a four-core USB data cable.
The base plate and cradle specifically developed for the Smartphone Integration option (6NF) is immediately recognizable by the two gold-plated pin connectors.
These two gold-plated pin connectors are also used as lock pins for the snap-in cradle adapter.
Plastic pins are used in the same position in the standard snap-in telephone cradle adapters.
In this way it is possible to distinguish at a glance whether the correct base plate is installed for the Smartphone Integration option.
