It’s compatible with the iPad and iPad 3G and can be used with almost any vehicle.
The Car Kit for iPad allows the iPad to be strapped to a headrest, around the base of the headrest or between two headrests. The FM transmitter simultaneously charges the iPad while playing the sound over the car speakers.
The Car Kit comes with a SimpleCase for iPad that has removable attachment straps both long and short, that can be used to attach the iPad to a car headrest, or between head rests. The straps can also be used as shoulder or carrying straps.
