Function sequence, call signal
The mobile phone receives a call signal via the following route:
- Multifunction antenna (A28/11)
- Direct line

- Direct line
- E-net compensator (A28/3) (with code (386) Comfort telephony and code (228) Stationary heater)
- Direct line
- Cradle (with code (386) Comfort telephony)

Information about the caller is displayed on the mobile phone's screen. The display on the mobile phone's screen is forwarded internally. At the same time, the call signal is forwarded to the audio equipment via the following route:
- Cradle (with code (386) Comfort telephony)
- Bluetooth module (with code (386) Comfort telephony)
- Bluetooth antenna (A2/91)
- Direct line

The audio equipment in vehicles with code (810) Sound system sends the call tone by means of audio signals to the sound system amplifier control unit (N40/3) via the Media Oriented System Transport (MOST).

From there, the ring tone is transmitted via direct lines to the following speakers:
- Center dashboard speaker (H4/27)
