Optional extras "USB/Audio interface" and "Smartphone Integration" require the installation of the ULF-SBX-High Interface box.
The USB hub is installed only if the car is ordered with the "Smartphone Integration" optional extra.
The mobile phone and the interface communicate via the Bluetooth antenna.
Voice output by the telephone system is via the vehicle's front right, front left and center loudspeakers. Volume can be adjusted by means of the multifunction steering wheel and the CIC. Speed-related volume control is also active.
Although both the ULF-SBX-H and the TCU may be fitted in a vehicle at the same time, the TCU always provides the telephone functions. In this case the telephone functions are not available in the ULF-SBX High and the module is only installed to provide the "USB audio interface" option.
