Description

This factory service manual covers the Xanavi NA6W-4200 Series Audio & Navigation Control Module (ACM), also known as the “Brick” unit, used in Ford Motor Company infotainment systems.
It provides complete diagnostic, repair, validation, and software update procedures for both navigation and audio control subsystems, integrating GPS, HDD, DVD, radio, and CAN-based control logic.

Engineers and technicians will find bench testing setups, wiring pinouts, and flowcharts for accurate troubleshooting, including step-by-step replacement instructions for all modular components (HDD, DVD, fan, display, PCB boards, etc.).
