Yesterday afternoon, the speed limit display (on the dash and head up display) on my Premier Pro started behaving erratically.

Most of the time it is displaying "LIMIT" in a white circle. Occasionally the speed limit flashes up for a few seconds, and then disappears. Obviously this is preventing me from using the SET button for the speed limiter and the adaptive cruise control.

It is not a camera issue; my entire 10 mile commute is within a 30mph speed limit, and I do not pass any speed limit signs. So it is not the signs that are triggering the short term display of the limit. The sat nav is working correctly, so not a GPS issue either.

Any thoughts?

Mine does the same in that it displays LIMIT until the vehicle passes a speed limit sign. When I live in town and drive around, sometimes I don't come across a single speed limit sign. But, any time I do pass a speed limit sign, it picks it up perfectly.

I understood that it also used a GPS database, which were overridden by roadside signs where different. My TomTom has a similar database, but clearly does not have the camera to detect signs.

Certainly this has been working perfectly until yesterday afternoon, displaying the speed without needing a sign to be detected by the camera.

Problem solved. It was the GPS that had failed.

I was showing as still on a ferry in the middle of the river, where I was 24 hours earlier. Yesterday evening, the GPS started working again after a while. Not sure what caused this - will need to keep an eye on it.
