All these changes are uploaded by Tom Tom owners following the steps here.These are then grouped into a single package that becomes available for download to navigator owners which register on the developer website and have the Home app installed on the PC.
This app offers raster maps, route creation, route adjustments and warns us if the route isn’t being followed.
These maps must be paid for but they are also the most carefully reviewed and updated.
Map Share is a facility by means of which the users can make changes to Tom Tom maps by correcting or modifying street names, blocked roads, turn restrictions, changes in traffic direction or in speed limits.
Moreover, with this software’s help you can import and use Google Earth’s (Maps) registered routes in GPS format.
Unfortunately there is no turn-by-turn guide or other complex features.
Taking into account that Tom Tom has a huge user database then the adjustments brought by Map Share will most likely cover most regions of the world.
