Suzuki chat-nav part 2 is here with Ant & Dec up to more of their dastardly adventures with unsuspecting members of the public. How exactly would you feel about a sat-nav system that spoke back to you while on your travels? Well, national treasures Ant & Dec put things to the test with the Suzuki Chat-Nav on the new Suzuki Vitara. In partnership with their Saturday Night Takeaway tv show, Ant & Dec take some unsuspecting test drivers for a ride with some ‘revolutionary’ sat-nav technology. Obviously the advert is very tongue in cheek, but how long will we really have to wait before we can start have a real conversation with our vehicle sat-nav system?!
