Bought a CX9 Azami AWD August 2016, speed limit never showed up on heads up but only on nav. had my SD card replaced as it was faulty causing the nav to reboot while driving on every trip. Even with new sd card no speed limit was enabled. All the boxes for speed limit were ticked in the settings tab. Spoke to dealer and was offered a test car a demo car which had the feature. looks like it's a error with the heads up its self. I'm still having problems with radar cruise control which has been determined as a design flaw.
