MagnaWorks(R), a business group of Magna International(R) Incorporated (NYSE:MGA), today announced the availability to vehicle manufacturers of Navex(TM), the first true, turn-by-turn telematics navigation system. Telematics systems differ from other navigation systems currently available because of their ability to provide true, turn-by-turn route guidance to drivers at markedly lower cost -- less than $500 per vehicle -- by using a wireless network.
