Dear all,
This is my first tutorial so, so correct me if something is not right.
Note: Firstly, always backup with Windows File Explorer
Step 1. Use your TomTom Home to update your Navcore to the highest version
Step 2. Eventually backup your device's content using the application
Note: Backup MapSettings.cfg manually from the map folder to keep your favorites
Step 3. Look at the compatibility charts (http://www.navitotal.com/topic18262.html) that corresponds to your Navcore version
Step 4. Copy the map to your TomTom
Step 5. Download the latest FastActivate at (http://www.navitotal.com/general-discussions-about-tomtom-f81/fastactivate-latest-update-jan-2016-includes-version-updater-tool-t14003.html) place it at device's root folder and patch your navcore and map
Step 6.Safely disconnect the device from the computer,
Step 7. Now that the map is correctly working and running, connect your TT back to your computer, disable auto backup in TomTom HOME settings and update your device to get the latest QuickFix GPS optimizations (for finding quicker satellites locations)
