When the HD2 was announced, HTC mentioned that an optional navigation accessory would be available (officially called the CU S400 Car Upgrade Kit) that would not only position the device for easy navigation in your car, but also charge the device through a special battery cover. Also unique to the CU S400 is that once the device is in the cradle, it will automatically launch the HTC NaviPanel for GPS navigation. The wait is almost over for the navigation kit, with Clove listing it as shipping in March or April with a price of £55, or around $90.
