I have had my CX-5 Sport Nav. from new for nearly 2 years. It is a lovely car with, as far as I'm concerned, one annoying niggle which Mazda doesn't seem to acknowledge. The speed sign recognition system immediately picks up all roadside speed signs which is excellent, it doesn't, however, acknowledge the end of speed restricted area sign (The black oblique line on a white background) If I leave, for instance, a speed restricted area the car still thinks it is in it, even though I have passed the end of restriction sign so consequently the overspeed warning comes on. I have raised this point with Mazda several times and they don't see it as a problem. I was even passed on to the technical department in Germany with the same result. Initially Mazda said that it might be a fault with my Nav. equipment but I pointed out that it is their system which has the problem as I have driven several Mazda's which all react the same. Mazda are still telling me this is a problem that only I am worrying about! I always keep my map and Nav. system updated.
