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.
Telephone Systems
The telephone system in the Golf is available in two versions. As a complete telephone system and a telephone preparation.
The telephone system or telephone preparation is only available in conjunction with a radio unit or radio navigation system.
It is possible to retrofit cell phones in a vehicle with telephone preparation.
On vehicles with telephone preparation, telephone operating electronics control module (interface box) is already installed at factory.
Only a corresponding adapter for the telephone bracket is needed. This depends on the mobile phone being used (accessory).
