Remove the screws, disassemble the button panel, and disconnect the wires connected to the panel. Remove the screws and take out the CD host, then unplug the original power cable from the head unit. Reminder: There is no need to disconnect the other cables, you can decide whether to disconnect and reconnect based on the difficulty of installing the vehicle model. Linux ScreenUser Manual 08/21 Linux ScreenUser Manual 09/21 3. Installation Steps - Wiring Connection Take the power cable from our product and route it inside the vehicle structure shown in the image below. 1) Wiring Arrangement Reminder: If your car has an optical fiber cable, you have to plug it to the host and pass through the new power cable. (Detailed images and explanations: 4.6 sound setup. ) Take the USB cable and connect the bm168 port to the screen, and the USB port will extend from the storage drawer through the internal vehicle structure. Check whether your car has an external Aux port. Usually, you may find it next to the cigarette lighter or below the central control screen. If available, connect the Aux cable and with the car Aux port and the new power cable. Reminder: Aux cable can only pass from the outside of the vehicle structure and cannot be hidden inside in any form. Remove the screws of the OEM screen and disconnect the wires connected to the screen. Linux ScreenUser Manual 10/21 Linux ScreenUser Manual 11/21 For the CD hosts, connect the new power cable with the CD host and the original power cable, as well as the fiber cable. But for the CIC system, the GND cable should be disconnected to avoid sound distortion. So please double-check your car system. 2) Connections For the screen, you have to assemble the bracket and screen first and then connect the cables shown in the image below. Reminder: For CCC and NBT systems, the GND cable should be connected shown as in the image below. Linux ScreenUser Manual 12/21 Linux ScreenUser Manual 13/21 4. Functional Testing Due to the particularity of the system, it is recommended to only open one function at a time, otherwise it may cause the system to run slower or other problems.
