As to the audible warning, this can be set to either a specific speed, e.g. 75mph, or the current speed of the vehicle, or whatever the speed limit is as detected by the Speed Limit display, or it can be switched off altogether.

In the few miles I've done I'd say the Speed Limit display is accurate most of the time, plus it picks up changes within a few yards.
Thanks for the clarification! Does the nav-screen also show the speed limit info for the road you are currently on, or does it only appear on the HUD? I was wondering if I needed to get the 'Speed Limit Info' option to display data stored in the navigation. I don't really care about having it pop-up on the HUD if it will show up in the nav screen anyway
