<P> Ford has extended the warranty for Sync on several 2011 to 2014 models to five years as a customer satisfaction matter . (Field Service Action Number: 12M02) </P> <P> On December 11, 2014, Ford announced Sync 3, which will replace MyFord Touch, will have simpler features and will be powered by QNX software by BlackBerry Limited instead of Microsoft . The Sync 3 name will be used for both Ford and Lincoln models, though Lincoln's will have a different theme .

A Cambridge Silicon Radio (CSR) BlueCore4 chip provides Bluetooth connectivity with compatible phones and devices . SYNC's major circuit board chips cost roughly US $27.80, which allows Ford to profitably sell the system at a much lower price than competitive offerings . </P> <P> In 2011, Shutko and Tijerina reviewed large naturalistic studies on cars (Dingus and Klauer, 2008; Klauer et al., 2006; Young and Schreiner, 2009), heavy good vehicles (Olsen at el, 2008) and commercial vehicles and buses (Hickman et al., 2010) in field operational tests (Sayer et al., 2005, 2007), and concluded that: </P>
