A lot of the GT's in Canada originally were from Quebec for some reason, so maybe that's what they called the colour in french, or he has that Custom STi TypeS Nismo OEM JDM/EDM/ADM interior.
The volume for the Bluetooth is those 5 buttons (numbered 1-5) on the bottom of the screen showed while on a call. Not very intuative at all. The volume knob and steering wheel volume will just control the music volume. Not sure if there's a way to change the ringtone itself.
