I have recently purchased a Start 52. I have installed the newest maps, but the speed limits for my home area are not up-to-date. I live in the London Borough of Lewisham. In September 2016 there was a borough wide 20mph speed limit introduced on all roads other than the Red Routes managed by Transport for London, and the main trunk roads. My Start 52 still has 30mph as the limit on these roads.
This means the speed warnings are wrong, and I wonder whether it would also effect the journey time calculations. Thoughts please.

Welcome to the Community!
I moved your topic to the Map Quality board where our Maps Specialist might be able to shed some more light on this. As for effect on routing, as Zsolt explained, routing is mainly done using the IQ Routes data rather than road speeds. For more about IQ Routes, please see here. The following video explains you more about how we do routing.

haha, so true... every single time when there is problem on the main road.. Now I would think twice before taking the suggested "green" route..
Hi, @Steam106,
In theory, you need to report such changes via https://www.tomtom.com/mapshare/tools/ .
However, based on my experience, DON'T expect any dramatic results! The last time that I posted a Speed Limit Error/Change, it was still "Pending" after 12 months. Even when finally accepted it can take over 6 months for the change to be incorporated into a Map!
