Anyone got a poor nav system? I have a CX60 PHEV - Dec 23. The nav system will not advise of speed cameras or average speed cameras. It does keep advising of congestion charge zones where there are none. Also, the maximum speed signs in the instrument and head-up displays are sometimes in error. It has displayed 10 and 80 in a 30 zone. I am off on a longer trip soon and do not expect much change. The Mazda techs have asked the gurus for help - I hope they have a solution. Has anyone experienced such or similar issues?
