Following an announcement at CES in Las Vegas by aftermarket infotainment system maker Pioneer, rival Kenwood has announced a revamping of its double-DIN multimedia receiver line. The firm revealed 15 new models, 12 of which replace a previous model in its Kenwood or eXcelon model lines. The big change that prompted the whole-line revamp was a processor upgrade, said the company, which improved stability and faster startup, along with a new native user interface, new shortcuts, and new solid-state memory that helps to double data-transfer speeds.
