New presenter Ortis Deeley joins the team as they travel from Edinburgh to London. Along the way, the hosts undertake a series of challenges, putting hi-tech tandems, wireless navigation systems, digital cameras, location-based games and portable media players to the test.

Jason Bradbury and Pollyanna Woodward head for the Brecon Beacons to test some of the latest electronic vehicles. How will they stack up against the demanding terrain and could a new car hire scheme revolutionise the way we travel? Next, the pair head to Skegness for a day by the seaside, each armed with a smart camera: complex devices that make most digital cameras look old hat. To round off the holiday fun, Bradbury builds his own version of mind-control game Mind Over Melon and invites people to blow up watermelons using just their brainwaves. What could possibly go wrong?
