  • Uses Ford Audio Control Protocol (ACP) to emulate stock 6 CD Changer.
  • Adds AUX audio input to vehicle.
  • Allows stock head unit playback control of iPhone.
  • Protoshield hand wiring diagram included in Resources folder.
  • EAGLE PCB files in eagle folder.

Directions

  • Open Ford_ACP_AUX.ino located in Sketch/Ford_ACP_AUX and upload to Arduino UNO.
  • Acquire parts on Bill of Materials located in Resources/LIU_FORD_ACP_AUX_BOM.xlsx.
  • Do one of the following
    1. Wire up Arduino UNO like shown below. Note: Updated pin 8 → pin 7 in latest code.
    2. Print PCB using provided EAGLE files.
  • Place the assembly in your car.

BLE vehicle lock/unlock.

  • Follow directions above but use Ford_AUX_BLE_control.ino located in Sketch/Ford_AUX_BLE_control and upload to Arduino UNO.
