Integrating contact PIM data into IVI has several unique challenges. The data must be available almost instantly after turning on the system and users expect good integration with their mobile phones and web services. A solution must be tuned for the specific needs of the UI and at the same time be flexible enough to be used in different models and car generations. In this talk, Patrick Ohly will present the solution chosen and enhanced for Tizen IVI over the last year: Evolution Data Servers stores contacts in sqlite, supporting direct reading for best performance. SyncEvolution caches phone address books using Bluetooth and PBAP. It synchronizes with cloud services via CardDAV, ActiveSync, or SyncML. andprovides a flexible unified address book. The entire stack is available as open source and developed in public.
