Start 52 not using the newly installed map

Hi, we have updated the maps on our TomTom Start 52 which are now showing, however, near us there is a new road (been there for a couple of years). This is showing on the map, however the route tries to take you down the old route...that is no longer there in reality, but still on the map!
Also it is not picking up on the postcode for Westfield shopping centre where we need to go next week.

It's a new device so not sure what we are doing wrong.
