Mine was fitted to a home made angle bracket that was fixed by two small bolts in the "spare" hole opposite the cigarette lighter. The holes are now hidden by the plug in the hole. The Parrot was sold on when I fitted the new head unit with direct bluetooth connection for the phone.
I did fit one to the 9-3, and the head unit was fitted in front of the gear selector. My wife drove the car and refused to use it while driving. It was only really fitted because she was worried about keeping in contact because at the time I was recovering from a heart attack and other operations...
I never took any photos of the finished job. But it was fixed by some sticky pads on a bracket, and the fixing hidden under the small rubber mat.
The parrot install is DIY really. if you get the right patch lead from
www.justcarkits.co.uk it will be plug and play. There's a connector for the phone behind the side panel of the centre tunnel, passenger side.
