Hi. Could someone please reply to this question. When I pass a speed sign eg, 30 or 40, it displays on the dashboard but only for around 100 yards or so then reverts back to a red circle with 2 dashed lines. Unless the car sees another speed sign soon after then displays that speed. Does this normally happen that the speed sign only on for a few yards, can the dashboard be set up so it displays all the time only change when the road speed sign changes. I'm getting old and i need to be reminded.
Many thanks
