Hey guys I'm posting on here to see if anyone was successfully implemented an idea I've been tossing around in my head. I was thinking of putting in a car PC and just tying into the factory lcd but have read mixed feedback of the screen being hard to read and then managing the shut off and turn on of the PC. I was originally gonna go with a raspberry pi and then a video signal converter and tap into the resistive touch screen.
But now I am thinking instead of the PC if I could use an MHL enabled phone like a S5 with the mimic G4 like in this video. https://youtu.be/lpL1krZvyEE . Then replace the factory lcd with a new touchscreen with a USB interface and a video card that could convert the factory 15k hz singal to vga and then the mimic g4 should send the touchscreen events to the factory system. This way the mimic g4 would control the switching over and I would keep all factory features. This way I don't have to account for a PC in the car and if it will drain battery or if it freezes up but it's hidden hard to get to. I just plug my phone in and go. If I don't plug it in I can just use the factory system with no problems.
What do you guys think? Is it possible? Have you done something similar I would like to hear about it.
Go even further with the HiKey960 + 7Inch touch screen.
But it's still a dedicated PC that is going to need management and some sort of internet connection to do everything I would want it to. My phone would already have that and all my latest music. Do you have a link from the 7" screen? I thought the factory one was an 8"

the hikey 960 has a WiFi chip.
You can create a hotspot using your phone's LTE connection and "share" it to the hikey 960.
A 7inch tablet fits perfectly in place. So I'm assuming a 7 inch screen will also be just right.
Obviously this is for a car pc but you can program the factory buttons to control the car PC which is cool.
If I can use the same drivers on my phone then I might use this interface.
I am working with an electrical engineer on a custom circuit to see if we can accomplish something similar.
The extra factory unit is sitting at my house. I will update later with what I found. But if you are going with a Car PC I recommned the GA-Net +
Also to the admins thank you for enabling this account. I wasn't trying to create multiple. I messed up my email when first registering but it is all fixed now!
Alright I finally got around to taking apart the factory unit. It is made of some quality parts. I took some high quality photos so anyone else on this adventure can benefit.
In case anyone is secretly following. I found this thread were other people were actually able to hack into the factory IEbus and read the events happening in real time. He was able to read the events from the touchscreen and use them to control his CarPc its a great read and the project is open source to help anyone going with that route. It does you to know some programming as you would have to load everything onto a PC and start programming events. But by hacking into the bus you could use factory buttons such as the buttons on your steering wheel or seek buttons to control your CarPC not just the touchscreen itself. Unfortunately the guy got to busy and moved on. But maybe his work will help someone in the future. As for my project. I have a very basic rough diagram of everything I think it will take to do what I want.
I will start by replacing the factory screen and then building some custom boards to accomplish what I want. This is a rough diagram with some minimum requirements that I wanted to share in case anyone has any input.
I have chromecast installed that has cell phone mirroring, with a hotspot in my car, i can screencast youtube, audio, videos. I can switch between the 2 and still retain factory navigation. Was that what you were looking for?

What are you using to switch between the video signals? and it has an HDMI input or are you converting to RGB?
You have somewhat of the setup I am going for. I found a couple of devices that together accomplish what I would like but I am still working with the engineer to create something that is an all in one.
I'm sure i'm missing a couple of things but below is what I have bought mostly from eBay. I use Localcast app on my Android phone to cast music, videos, Youtube, etc. Total cost was around $200 something.
$8 - Mini Composite 1080P HDMI to RCA Audio Video AV CVBS Converter Adapter For TV
