remove main fuse/battery cables before proceeding.

allen driver.
2. Connect the OEM USB and radio antenna cables disconnected during removal of the OEM head unit
to the matching sockets on the back of HDHU.14. If either are di󰀩cult to connect, verify the orientation

Bluetooth calling microphone will be used, secure it to the desired installation location, then route its
cable to the corresponding input on the back of HDHU.14.
