The Control Unit is a small black box. It measures 2.15 x 2.15 (3.15 with the antenna) x 0.6 (1.2 with the wheel) inches (WxHxT). At the upper left corner of the device, there is a small stub antenna that is used by the integrated GPS Receiver. There is a 2-inch 262144 colors display with a resolution of 160x120 at the front panel. The display's Brightness and Contrast can be adjusted and it is bright enough to be seen clearly when installed on the car's dashboard. It is also easily read in the dark too. The display dims after a while so that it does not glow annoyingly if it's dark and if you don't use it at the moment. There are three buttons under the display: TALK, HANG UP and Rotating Wheel (that can also be pushed), which is used for navigation through the menus. The TALK and HANG UP buttons are relatively big and are easily pressed. They are made of glossy black plastic and have a good response. They're lit respectively in green and red. The Rotating Wheel between them is made of rubber. It is solid and it does not slip even if your hands are wet due to sweating while driving. It is a pity that it's not lit, but this is not a big problem because the wheel's rugged surface combined with the light from the display and the other two buttons make it easy to find even in the dark. At the lower left side of the device there is a 2.5mm connector for the microphone.
The other part of the car kit is the blue box of the Universal Radio Mute. It measures approximately 4 x 2 x 0.8 inches (WxHxT). At the front side there's a logo and the web site of Parrot, and there are two connectors on the side: one for the display, and the other for the cables connecting the radio to the car. At the opposite corners (upper left and lower right) there are holes used for installing this box inside the car's dashboard, so that it is not seen in a completely installed system.
