I probably mentioned this already, but it is not terribly hard to remove the speed-related restrictions if you have a cable and a laptop. Made all the complaints about sat nav input, pairing Bluetooth, SMS reading, etc.... go away. Also kind of disappointing they still haven't figured out the bugs related to displaying/updating messages......the MZD Connect system is wonderful in some ways and still struggling in others.
Another thing I don't understand is why the forward-facing camera (on vehicles so-equipped) used for the Lane Departure Warning system can't also read traffic signs and augment the speed limit display in the sat nav. Would also be able to recognise whether overtaking is permissable or not. Stuff like this has been out for many years....
