When you’re driving in the UK, the navigation might show wrong speed values. The navigation will show the value 25mph for a speedcam with the speed limit 30mph, 37mph for 40mph and 56mph for 70mph.
We write the correct speed values into our database. You can see this in our map. The database file also contains the correct values. Nevertheless, the device software/firmware transforms these values when you’re inside the UK. We don’t have any idea why the software by Harman/Becker does this. Unfortunately, it is beyond our control to change this. We have made many attemps with many customers – without success.
However, you can rely on the fact that each and every speedcam that is shown on our map will also appear as a warning on your device. Please keep an eye out for the correct value while on the road.
