That is not my maserati QUATTROPORTE manual says at all. Are you refering to a Granturismo manual ?
Nope I'm looking at the technical documentation that comes from the training academy.
Proceed as follows to check the SW version of the Bose NIT:
• Select the radio function
• Press and hold the MENU button and the “1” button simultaneously until the “Silverbox” menu is viewed on the screen.
• Select and confirm with the right hand knob to view the software version.
The paragraph I quoted also contains the following:
The antenna amplifiers of the Bose NIT are not connected directly to the NIT but their signals go through the tuner (Bose Tuner Box) positioned in the luggage compartment.
• Two +30 (direct positive) power supplies arrive at the NIT.
• The EIPMP module (optional) is an interface box for the optional iPod connector and is fitted underneath the NIT unit.
• The Array microphone contains multiple microphones for the hands-free calling, voice controls and Audiopilot® functions. It is fitted in the roof console.
• The (optional) analogue TV receiver is not an external unit but is integrated inside the Bose NIT.
