Works perfectly on TB78 with Google Agenda & Contacts, very easy configuration ! thank you so much.
Install "Provider for CalDAV & CardDAV" and also "TbSync" from the same developer.
Then change this setting following the instructions from the developer : https://github.com/jobisoft/DAV-4-TbSync/issues/240

This review is for a previous version of the add-on (1.24).
