Telephone operation function 

The portable CTEL (A34/6) is inserted into the UPCI [UHI] portable CTEL holder (Universal Handy Interface) (A34/15) in the center armrest and is thereby connected to the Universal Portable CTEL Interface (UPCI [UHI]) control unit (N123/1).

The Universal Portable CTEL Interface (UPCI [UHI]) control unit is connected to the Media Oriented System Transport (MOST) bus.

The telephone function is a component of the Universal Portable CTEL Interface (UPCI [UHI]) control unit. Menu and user guidance, however, is a function of the radio (A2).

User guidance can also take place via the multifunction steering wheel or via the portable CTEL keys.

Making phone calls with the portable CTEL inserted is only possible in hands-free mode.
