AVING have some nice images of the docking station for the Kohjinsha 7" LX800-driven UMPC. There's also some news about other accessories.

the peripherals include USB-enabled T-DMB receiver, HSDPA model, and navigation package composed of USB-enabled GPS antenna, navigation software, car-use cradle, and car-use DC adapter.

Multi-use docking station.

It looks like the accessories are just USB modules but the docking station is a great addition. My only problem with the car pack is that this device doesn't have a touchscreen!!!
