10.25 inch android headunit installed












I have a 10.25 android 10 with Snapdragon 625 4GB / 64GB and NTG 4.5
I also am going to see if I can try and split one of the camera signals - the unit supports recording of a video signal through an RCA input port (so CVBS or perhaps a digital equivalent), I got this hoping that I can split the signal for either the front or rear cameras: Fakra Z Plug Male long and Female to RCA Female Vedio Adapter Extension Cable 6" | eBay (RCA to the roadtop DVR input)

i’m worried if I have to actually wire to my aux in or not - which I’ve read is not required but likely needs a configuration change in the engineering mode.
if anyone has any explicit information on that it would be welcome.

So far:
- Removed the factory screen
- Removed the A/C vents
- Removed the Comand unit. What a pain in the ***. In my '11 A207, none of the trim had to come off. I unscrewed the top screws until they got hard to turn and the unit would wiggle but not come out. I unscrewed some more but I didn't want the lock bars to fall off, but kept going until I could feel the bars not hitting the hooks on the head unit.
- I installed the wiring harnesses and connected it to the Comand and Android screen
- Issue 1 - no sound. After rereading another set of instructions that didn't come with the unit, I realized I needed to move the fiber optic from the factory harness plug to the Android plug that goes into the Comand.
- Issue 2 - I tried several Vehicle Display settings, starting with NTG4.0 (2008-2010) and I'm still getting No Signal.
- Issue 3 - They sent me the GPS cable splitter so I can use my factory GPS antenna. The factory plugs on the Comand have a double wire/plug in 3 locations - Blue, White, and Green. The GPS should be Blue like they are on the splitter but not sure which wire to install the splitter.
Great resource

also in yours do you need to open up the console to plug into the factory audio aux in?
My car doesn't have an AUX port but it has an AMI port in the glove box. The kit came with an AMI to Aux cable. I'm going to run the USB and AUX to the glove box.

- Issue 1 almost resolved. I'm getting sound from the factory system. The Android system works through AUX which is an AUX adapter in the AMI port. I set the radio to AUX and go to the Android screen. I play music and it comes out for 3 seconds and shuts off. The Comand is auto-switch from AUX to Media Interface.
- Issue 2 resolved. I didn't have a power source going to the display adapter, duh.
- Issue 3 workaround. I'm going to use the GPS antenna that came with the Android and hide it behind the A pillar cover. Easy solution.

It took about two hours to route the big harness properly in order for the Comand unit to fit back into the space. It was very frustrating figuring it out but patience prevailed. I ran the harness through the Comand space to the lover back left corner and up the left side to the screen space. I only left the T connectors for the main Comand plug. One in the back of the unit and the factory-Android tucked down in the bottom of the space.
I'm routing the USB and AUX plugs from the Android harness from the space where the old screen was to the glovebox. I managed to get some string routed and will finish up tonight. I didn't remove the glovebox which made it harder. I popped the AMI port out and ran the string through there. I'll notch the side of the opening so the cables can come through and pop the port back in when I'm done.

What are you trying to install one in?

I dropped the glovebox because I'm OCD about clean installations. I didn't want two USB ports dangling in the glovebox so I ordered a dual USB port and will install it when it arrives tomorrow. Then the only thing left is to reinstall the glovebox.

Some screen is different then posted picture here, I don't know why.
On home screen for some unit - main icons which I can swipe left and right - show current car status by graphic, like opening doors, mine is not.
And original command screen, other shows like these pictures:
Right side has graphical information
Left side you can see sensor information
This picture is from other member, but mine is exactly same, except this shows NTG 4.0, mine shows NTG 4.5.
Right side shows nothing but speed. Reverse mode also same style screen shows. No car graphic and more info.
Is it depend unit's software and firmware version?
My unit comes with Android 11, and seller said this unit has latest firmware/software....
Any suggestions?
