And there's two temper proof seal as well. (void factory warranty)

Just becareful when you hook the two new ribbon cable. they are quite fragile I found.

And, ground yourself before you do anything inside the headunit.

I've also succesful installing the backup camera, however, the car original came with a "Solder" on switch, I didn't had the patience to resoldering it.
I left the switch un-operable.

Too bad, I sold the car in August.
But I can provide tips when you guys gets the material.

thanks for your help

Or can I stream music via Bluetooth from the Android module and have navigation going on at the same time?

It's so confusing.
Let me explain how this system works.

PART 1.
---------
Basically, we are cheating the original OEM headunit and feeds video to the original display monitor. The audio of the headunit is NOT modified. Audio is output via the AUX, 3.5mm jack inside your armrest compartment.

The original headunit is basically, separate into three main component.
1. The disc drive unit.
2. The monitor
3. The motherboard.

All 3 above are interconnected via ribbon cables.

We are trying to intercept the video feed from the motherboard to the monitor.

The add-on kit that you purchase from the Aliexpress seller will have the following main components
4. An PCB that intercepts and control video in and video out to the monitor.
5. An interface control box
6. Android box

Part 2
----
How the system works,
A. The interface control box controls the MODE you want to operate.
i. By press and hold the Navi Button for 2 sec, it will switch to the interface main menu.
ii Once in the menu, you can select the video input you wish to select.
iii. You can enable and disable which input you want from the "SETUP", language setup is here as well.
iv. Then you will found two "Home Button", one to go back to the interface, another one for the Android.

Part 3
----
How audio works:
A. The audio feed from the Android must be connect to the AUX stereo 3.5mm jack inside your armrest compartment. This is how audio is output to your speakers.
B. All other function of your original OEM headunit still function and remain unchanged, including Bluetooth, USB (inside your armrest compartment), CD/DVD drive, Sat Nav, Sat Radio, system HVAC and other car parameters still works.
C. You can switch in and out of the Video interface, while keeping the original audio (BT or Sat Radi or AHA) or Nav. Then you can switch back to AUX for Android audio.

Part 4
----
How to operate:
A. Once everything is connected properly, to switch between Interface/ Android, press and hold the "NAVI" button on your radio.
B. For sound on the Android, switch audio on your radio to "AUX".
C. To go out of the Interface/ Anrdoid, press NAVI or CAR button.
D. There is two USB port on the Android unit, you can buy USB extension cord and route it somewhere more convienent. Only FAT32 or exFAT format will be recognized. No NTFS.
E. To use Internet on the Android, First Enable Hotspot function on your phone, then go to the Setup menu of the Android, connect your phone Hotspot. (This is the only way to connect to Google Play Store and other online stuff.
F. I found our Resistive touch monitor is difficult to use, so I added an USB airmouse, it has an keyboard on one side and mouse function on the other. Extremely Practical to move the apps around the Android Screen Aliexpress-Airmouse-Keyboard

Part 5.

Here are two very useful document to use for installation and understand how this whole setup works.

That was the most helpful, clear and direct post ever. That paints the "big picture" for me.

Thanks for going above and beyond.

I'll keep this thread updated with progress.

This is the screen calibration screen, it shouldn't come up everytime you boot.

When I start up my PMC every time go there?
1 - No, you should go to the "Interface, setting to disable to onboard backup function" Your OEM camera should work.
2 - The black screen is for screen calibration, it shouldn't come up every time you boot.

For the language, camera setup it's all going thru the interface page.

Remember this page I show you?
It's all in here to do the setup.
Change the language to English, then it should self explained.

I am planning on installling in stages...if possible.

Can I install the PCM card only then later install the modules?

Will the radio still work, looks like that on the videos?

Yes, that's fine. Before you close the head unit, install the card and route the wire bundle out, then you could install the rest later.

It won't affect the pcm and radio.

USB connection from Android module

There are 2 USB connections off the Android module. What are they used for?

Does the external speaker need to be plugged into the Android module? I don't think it's needed.

Do I need to use RCA connectors from the Android module to the a/v input on the switch module?

Do any changed need to be done to the dip switches?

Mine did not have any instructions.
