COMPUTEX VIDEO: Japan's Clarion showed a new prototype of its personal navigation device that combines internet access, a multimedia player with digital TV and GPS all-in-one.

The greatest difference between the latest prototype and previous model is its shape. This video shows what it looked like at CES in January and has a first look at the prototype unveiled today at Computex in Taipei.

This year's Computex show promises to be one of the most exciting for years, and PC Advisor's dedicated video reporter Martyn Williams is there to capture it all.
