Please remember doing the work slowly and carefully, don’t force anything and don’t rush. If you have any questions while installing, just stop it, then contact DVDGPSNAV for help, you can take some clear photos to show and explain all your doubts or questions. If you are really don’t know how to start and have never installed an aftermarket head unit before, just ask a professional car stereo shop to install it for you, the installer should be responsible, because he may not install such a unit before and he may have a question while installing, a responsible installer is willing to ask for a help from the supplier of your Android head unit.

So let’s get started.

1. Factory dashboard with 6.5″ small screen head unit from 2012 BMW 320i with working aux.
   
   This is the factory display which will be upgraded with a new 10.25″ larger touch screen
2. Firstly use a trim tool to pry the corner of the trim and gently pull out the air vent, remove the 2 plugs behind and set the vent aside.
   
3. Remove the 2 screws(left and right side) to free the CD and climate control panel, then pull out the cover panel.
   
4. Remove the top 2 screws to free the factory screen, and gently pull out the screen, remove the LVDS plug behind.
   
5. Remove 2 screws of the CD player, so that you can pull out the CD player.
   
   
   You need to unplug the harness behind the CD, so you have got 2 plugs, one female wiring harness and one male plug behind the CD, connect the female harness with the new male plug, connect the male plug behind the CD with the new female plug.
6. VERY IMPORTANT NOTE:
   If there are green and black fiber optic cables from your factory wiring harness, you will need to move them to our new plug at the same position, if not, there will be no sound or the unit will not work properly.  Gently lift the indicated tab, and slide out the connector for the black and green optical cable, then install the optical cables in the same position in the male plug of the provided adapter cable.

   
   
   
   

7. Now you can connect the 2 screen cables with white plugs, 2 plugs from the back of the screen, 2 plugs from the main unit: LVDS, TO-TFT, if you check the connectors carefully, you will find which cable should connect which connector, that’s easy to find it out.
   
8. Connect factory LVDS plug with the main unit named CAR-LVDS. Connect the provided black small plug with CAN connector, and connect other plugs with different colors to the related connectors from the unit.
   
   
   Important note: Please check the connectors carefully, then you will see every plug is different, make sure you don’t connect wrong, and don’t use force to push the plug into the connector, if the plug matched, you should be able to push it into the connector easily.
   
   Note: You can click the above image to view larger.
9. If you want to connect an aftermarket rear view camera, firstly the camera should be powered with your car reverse light, secondly, there are one green cable with RCA connector to connect the video input from the camera, and there’s a loose REVERSE wire which should also connect the red trigger line from the camera.
   
   Note: If you have connected the camera correctly, but still no signal or the display is not stable, that’s because the voltage from your car reverse light is not stable, you can connect a relay to solve this, if you need more info about the relay, you can contact us we can send you some pictures.
10. Double check all connections, install the new screen at top, reinstall the head unit and A/C controls and other things, since you have already done how to remove these parts, you should also know how to reinstall it back to its position.
11. After all was done, it’s time to test, turn on the car and watch the screen to boot up, and test function.
    
    

    
    
    

12. If there’s no sound from Android menu(music or video playing), firstly please check if you have activated factory aux mode, switch to aux mode, and see if aux can be selected, if it’s dark grey and can not be selected, please check if you unplugged the iPod.

    After factory aux mode has already been activated, if still no sound, that’s because your aux wires don’t go through factory CD or factory Aux wires from the plug behind the factory CD don’t match our aux wires from our plug, so you can connect factory 3 aux wires(red,white and black color) with our new aux wires directly to get sound, or you can use our special aux-adapter cable to connect your 3.5 mm aux port directly:
