“ Specifically developed for Citroen, provides location specific warnings on traffic conditions via car's, on-board stereo system, operates on all England's motorways and major trunk roads „
The system came with a second hand car a bought. A bit over the top, or so I thought. A voice and light system alerts you of any delays on the motorway and trunk road system in thr UK. The voice can be turned off and when a red light appears you can press a button to find out the problem, or in automatic mode it warns you by voice. It can be taylored to only give advice on the direction and road you are currently on, or a radius around your vehicle. At a subscription of £30 a year, even if you don't drive much I think it is worth it.In short a polished and compertent system, not without it faults.As with all satnavs and the like, it is a tool. Learn to use, and it will reward you.
