Renault has unveiled the cheapest built-in satnav on sale, with the launch of the Carminat TomTom system.

Standard on higher trims and costing under £500 as an option on others, it will be offered on the new Scenic and Grand Scenic launching this June, as well as the new Megane and the facelifted Clio range.

“Despite the high demand for embedded navigation, it remained expensive, complicated, mainly limited to luxury cars only and featured content and maps that were outdated before the car even left the dealer,” said TomTom boss Harold Goddjin.

The system can be updated online for free from any computer and features a 5.8-inch screen, speed limits and camera locations, points of interest and traffic updates.
