Hi guys and girls

I’ve started you use the motorway quite a bit lately and I’ve noticed if I want to go 70mph the speed on the clocks must be 76 mph is this common or do I need a software update or something

Thanks

It's common for speedo to be out to gps speed, it's doesn't sound to far as it's only 10% saves you getting a speeding fine.
Oh that’s good as long as it not just me
Thanks

Speedo will never be 100% accurate. As tyres wear, the circumference lessens, and subsequently will affect the speedo reading.
Mine is off by about 2.5 miles. Quite normal on any car. Smile
