Function requirements:

IMPORTANT Making telephone calls in "private mode" is only possible by using a Bluetooth headset or in the rear using a Bluetooth handset.

The combination of the Universal Portable CTEL Interface (UPCI [UHI]) control unit and the relevant UPCI [UHI] portable CTEL holder (Universal Portable CTEL Interface) enables different portable CTELs (e.g. Motorola) to be operated. Equipment (e.g. laptop) with Bluetooth capability can also be operated.

The Universal Portable CTEL Interface (UPCI [UHI]) system consists of the following components:

IMPORTANT On model 221 up to 31.8.06, voice input takes place via the 4 microphones integrated in the hands-free system microphone group in the inside rearview mirror unit (A67)

On model 221 as of 1.9.06 and on model 216, voice input takes place via the 2 microphones integrated in the hands-free system microphone group in the inside rearview mirror unit.

The UPCI [UHI] system contains the following functions:

The volume of the audio speaker system can be set individually by the user. This can be done via the buttons + and - for setting specific functions and volume control integrated in the multifunction steering wheel or via the portable CTEL.

The functions are indicated by several displays (e.g. "ENTER PIN"), which notify the user of the operating condition of the portable CTEL, in the displays of the following components:
