This part of the standard is a representative example of possible customer experiences in terms of in-vehicle multimedia functions and features. These functions and features will be enabled by implementations of foreseeable technologies. This document covers representative use cases in categories of commerce (abbreviated as COMM), customer relationship management (CUST), emergency (EMER), entertainment (ENTE), fleet management (FLEE), guidance (GUID), home automation (HOME), information (INFO), messaging (MESS), mobile devices (MOBI), customer preferences (PREF), productivity (PROD), security (SECU), service and maintenance (SERV), user interface (USER), safety (SAFE), Bluetooth (BLUE), intelligent transportation systems (ITS) and combination use cases (COMB). Each of the use case categories has at least one high-level use case, which describes customer experiences in a more generic fashion. A high-level use case is denoted by CASE x, where CASE is the four-letter abbreviation of the category and x is a natural number. A use case category may have low-level use cases. A low-level use case has more information about specific ways of rendering functions and features than the corresponding high-level use case. A low-level use case is denoted by CASE x.x. This document does not cover all possible use cases.
