Too unreliable, if it works it's excellent. But getting into the car not knowing if it might work isn't good enough. It will work find in the morning, then for no reason on the drive home, it won't recognise at all! Or vice versa, there is no pattern or sence to this. Luckily my car has full traffic sat nav but if I was reliant on this or bought a car thinking this is a good solution, I would be very upset.
