Summer holidays are sadly upon us, leaving the streets teeming with the nation’s young. It’s bad enough trying to dodge them out in the open, so I can only imagine the horrors of being shut inside a slowly moving vehicle with them en route to some child-friendly holiday location. Parents everywhere will be praising Vieta for kindly developing a Freeview box that works in the car. Digital TV on the move should mean you get less interference and fewer signal woes. The TDT500C is a black box that you can hook up to any LCD in-car monitor. It will also integrate with existing car stereo, games consoles and DVD players. Pretty much everything you need to ensure that you don’t have to speak to your children at all during any journey. At £399.99, it’s expensive – but what price tranquility?
