Please recommend a car satellite navigation system which shows london congestion zone?

I don't need any fancy, just the directions and the london congestion zone. Will probably buy from ebay and want to spend between 拢60 and 拢80.


I would like recommendations on a brand and model to go for please.





Thanks|||There's big red signs with a white "C" on them and it's painted on the road, you don't need sat nav.
