Traffic sign Recognition

[siteguru]

Mine is hopeless whatever it's using. I just disable it. The thing shows national limit dual carriageways (70mph) as 60, national limit single carriageways (60mph) as 40. Waze, on the other hand, is correct all the time (so far at least).

Since I got SC077 (or at least, it's since then that I've noticed it), when mine encounters a NSL sign it now shows the speed as 3 dashes. Previously it would show 60 regardless of the road type.

Mine is as hopeless as the rest - and it definitely does not use the nav data, at least while not using the onboard nav. I never use the onboard nav so I can't say if it would when it is enabled.

It reads the speed from map data whether nav is one or not.

Mine doesn't. The speed goes blank if it doesn't see a sign with the camera and the nav off.
If it were reading it off the nav it wouldn't go blank.
If it were reading off the nav it wouldn't show this, misread by the camera, as a NSL when I'm in a 30mph zone.

Mine shows speed limits on roads with no signs at all. If it's not map data then perhaps its clairvoyant.
