Hi thanks for the reply, the version of my map is nr, 7.
I would like to update only the maps because I am afraid of not being able to update the whole system and I don’t know if it would be possible to go back if something does not work. Thank you
As @SaNdMaN pointed out above, you can update the maps only, or apps and maps. Since you are on Sync 3.3, you will be able to revert back from Sync 3.4 if you wish.
