As far as I can make out, there is no way for current speed to be displayed. The system can be made to beep if the speed limit is exceeded and the speed limit is displayed (on faster roads) but not the car's actual speed.

Has anyone else found a solution?

Look at the speedo?!

Not accurate! Overstates by 7%. True speed 70 MPH, indicated speed 75 MPH.

Would that not mean everyone will get a speeding ticket using a capture?

Speedos are renowned for over-reading. It "helps" people keep to the true speed. The only "true" speed is the speed the law enforcement agencies say what you are doing.

No. On my Captur, if the speedo reads 70 MPH, I am only doing a true speed of 65 MPH.

Most trafficlaw enforcement agents use radar and not satnav readings to determine the speed of the subject. So it is not advisable to use the satnav as the means of determining one's speed. Furthermore, satnavs have an inbuilt error, as they do not resolve down to a fine detail; only to a few metres. One can see this if one deviates from the course chosen by the satnav. It takes several metres of deviation until the satnav snaps back onto the actual road upon which the car is travelling. The error is typically 3 metres.
Another error with satnav is the vertical distance. Travelling up or down hill will introduce further errors in the satnav speed reading.

Speedometers are designed to never read less than the actual speed, and are permitted to read up to 110% of the actual speed + or - 6mph.

According to Tom Tom, at 60 MPH on the flat, the error bounds are 0.5 MPH - much better than a speedo.

Ran a test the other day to establish a better idea of the accuracy of the speedo in our Captur. Our trust portable SatNav suggested our speedo overreads by 2-3 mph so definitely one of the more accurate examples we have owned in recent years.

The speedo is one of the best being digital you can assess actual speed. Remember most cars have a vague arrow on an analogue system. Stop moaning!

Car Speedos are governed by law and regulation by the EU. Satnavs are not. Whilst the satnav probably gives a more accurate representation of speed and distance, especially over faster speeds and longer distance, it is unlikely to serve as a mitigation in a court of law, should one find themselves there for a speeding offence.
So I suggest using the speedo at all times, with due regard to the legal specification laid down my EU and UK law.

Just trying to be helpful, and not mislead.
