I have surprised in the past to find that all my favourites have been erased after updating a map with the TomTom Home application.

This was extremely frustrating, so to make sure it doesn’t happen to you here’s what you should do

The favourites are stored in a file called MapSettings.cfg within the map’s folder.
Take a copy of the file before you run the update and copy it back to its original location afterwards.

<Device Root>/<Map Name>/MapSettings.cfg

Hope this helps!
