Backup favourites to SD Card for Android

Hi,

Is it possible  to backup My places, My routes and/or Navigator settings to SD Card ? I think we can't backup the TomTom license. If I uninstall Navigator and reinstall it from Play Store, will I lose all the favourites previously created along with the TomTom license ?

My problem is that Play Store doesn't let me update Navigator from 1.0.35 to 1.0.48, I can only open or uninstall it, so I wanted to force it with uninstall / resinstall.

Best regards
Florian
