This is a problem I've experienced since soon after I bought my GO 750 LIVE but has never been resolved. I've had 4 very long threads with TomTom Support over 4 years and it's still not been resolved. Two of the threads were closed by TomTom whilst I was waiting for a response from them! On 2 other occasions we had to close the thread because the road works had finished and the problem didn't show anymore.
When I'm driving through roadworks covered by average speed cameras the device will 'stick' at unforseen points and for an indefinite time it will show the wrong speed. As my GO is at eye level it's easier to check your speed on the device rather than look down at the cars speedometerwhen driving on 2 or 3 cramped lanes with lots of other traffic. It is really frustrating when you find that your actual speed is perhaps 10mph above the speed shown on the device as you've very slowly increased speed whilst the device is still showing the wrong speed. It can also happen in reverse. Having increased speed (perhaps to get past an adjacent lorry) the device speed has not decreased as my true speed has.
I have never experienced the problem during driving on normal stretches of roads.
TomTom have stated that there's nothing wrong with my device but none of their many recomendations (many illogical and others plainly wrong) have made any difference.
