Message Access Profile (MAP) specification allows exchange of messages between devices. Mostly used for automotive handsfree use. The MAP profile can also be used for other uses that require the exchange of messages between two devices. The automotive Hands-Free use case is where an on-board terminal device (typically an electronic device as a Car-Kit installed in the car) can talk via messaging capability to another communication device (typically a mobile phone). For example, Bluetooth MAP is used by HP Send and receive text (SMS) messages from a Palm/HP smartphone to an HP TouchPad tablet . Bluetooth MAP is used by Ford in select SYNC Generation 1-equipped 2011 and 2012 vehicles  and also by BMW with many of their iDrive systems. The Lexus LX and GS 2013 models both also support MAP as does the Honda CRV 2012, Acura 2013 and ILX 2013. Apple introduces Bluetooth MAP in iOS6 for the iPhone and iPad.
