The TT isn’t a device, it’s a program for TomTom GO, One and Rider
sat-navs. Based on the award-winning database used in the Talex Lite, it covers fixed, mobile, SPECS and red light locations, and is directional. In tests it performed perfectly, speaking a warning and a speed limit (also flashed up on the screen) and issuing a ‘bing’ when passing the trap.
