GM5 Redesign

GM-5 Redesign

The General Module 5 Redesign (GM5RD) is the heart of the general vehicle electrical system. The GM5RD, which was used on the (E85)Z4, has been further developed for the (E83) X3 SAV with a combined K/LIN bus module. The K/LIN bus module is integrated in the GM5RD for operation of the door mirrors.
