Many people have wondered if the construction updates for Map Point would end up updating the maps that Map Point uses. This is not the case unfortunately. As with many other navigation software packages, the only way to update the maps is to purchase the newer version of the software.

Below is a quote from Chuck (the lead StreetDeck developer) with an explination from a seperate thread:

Construction updates will not do anything in StreetDeck.
