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.
We can also get free maps for Tom Tom if we follow the sales available in their shops or the Internet.
By connecting the device to the PC and activating Tom Tom Home it will prompt us when we can download the available updates from the Map Share package.
Another great advantage is that compared to paid maps which come out only several times a year, the free updates for Tom Tom included in Map Share are updated monthly or even daily.
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.
Except Map Share, there are several other independent projects which are try to provide free maps for Tom Tom using Open Street Maps that we have talked about here .
