Updating Sync 3,0 to 3,4 with navigation

Maybe a stupid question, i would like to update my Sync 3,0 to 3,4, i have already updated my navigation.
Is it possible to update only my sync with the old maps?

No, you can’t. In order to install 3.4, you need to reformat the unit, thus erasing everything.
