Cygnett's GrooveTransmit can be a bit of a bugger to set up, as its bendy arm is on the stiff side, requiring a good deal of force when configuring it to suit a car's dashboard layout. Also, it requires an incredibly firm shove to get it into the cigarette lighter socket.
The cradle features a depth adjuster and padded, moveable arms so that any type of iPod (excluding the Shuffle) or iPhone can fit. Once within the GrooveTransmit's embrace, iPods and iPhones do sway and jiggle a little bit. This is rather an issue with iPod Touches and iPhones, as their big glass displays tend to catch the eye, especially when it's busy reflecting daylight.
Whenever we packed the GrooveTransmit away, we resorted to pulling the arms apart manually, as the arm release switch, on the back of the device, is not only hard to find but finicky to use.
As the cradle is fitted with one of Apple's proprietary iPod/iPhone connectors, your favourite device from the house of Jobs will be recharged as you use it. At the bottom of the cradle is a display for the current FM transmission frequency, as well as four buttons to store and recall frequencies. On each side of the cradle's base is an up or down switch for adjusting the current frequency.
