So did everyone just give up on development of this thing?

 

When I heard this system was open source I got visions of custom themes, and taking advantage of the hardware in new and exciting ways... Like gauges and stuff.

 

Let alone enabling Android Auto or free use of backup cam for less than the $1,000 other companies charge...

 

 

People don't understand that open source ISNT. It just happens to utilize SOME open source components lol They are required to disclose what open source components they use and the code IE busy box etc... these aren't even close to open source but they do use some components.

The intent was for this project to be open source. I don't have access to the firmware nor time to reverse engineer the HMI module meaning the project is at a stand still.

 

For the time being you will have to rely on those who have capitalized on access to gm equipment for updates and modifications.

Hey I have the usb update files and map update files you’ve been looking for! If you got some programming skills I could really use the help making a way to boot into this HMI and try to get access to a file directory. Here’s my bench setup so far.

I believe steering wheel controls would be through the LIN bus, you may have to get the PAC or Metro steering wheel controls retainment kit, if they make one yet.

Hi,

 

I see there is a lot of HMI experts on this thread.
Please help me undarstand few things...
I'm base in Poland (EU) and wanted to convert HMI to have a EU maps and language.
After doing researching I figured out that I cannot do that on NA module and have to replace to EU module.
So I found one for Opel Insignia (Buick Regal) and used foreign VIN (from EU model) to unlock the HMI module. All programmed via SPS.
Guess what? All is working great! I have a EU maps, voice recognition and all other features meets EU specification.
So let go for question now because this is not my first and last GM I want to import from USA and convert to EU specs. :)

 

1. Do I really need to replace HMI module to EU version to get EU specs?
2. Because I used VIN from the car that has rear A/C and video (my car does not have) I have control icons on CUE screen now for those systems which I don't have.
    Do I have to find a proper VIN to hide it or may I use my car VIN to unlock EU module and it should work?

3. What is the different in mentioned here "calibration" and "software" and what actually the open source does?

 

Thanks!

Woj

The CAN bus is jumped through in the module. I'm not sure what side is in and what side is out yet until i meter the wires.

The MOST bus is intriguing as it is an A/V bus connected through the HMI, Instrument Cluster, DISC Player, Display, Amplifier(if applicable) and Radio. MOST bus is also jumped through in the module.

The LIN bus I think hits the buttons like steering wheel, hvac controls, media controls...

 

I'm still investigating the system setup to further evaluate the next move, rather breaking the HMI software and reusing the hardware, or building a new bit of hardware. My only issue is a MOST controller is nearly impossible to come by. Although there are some aftermarket MOST integration products for foreign cars.

The HMI is actually pretty decent at a glance, it has 8Gb DDR3 Ram, 32Gb eMMC, LIN, CAN, MOST50, Accelerometer, BT/Wifi, GPS.

 

I'm may start finding someone with one of the nav map updates to see if they'll share the files. It may have some insight into the update process and maybe an easy way into the software. Otherwise steps will have to be taken to try and read the eMMC memory.

 

More to come...

   Can you indicate were the back up camera wires are connected? I got the OEM camera, but do not know were is connected since the truck does not have the hareness that comes from the tailgate, but have all the HMI conectors available.

 

Thanks

I pm'd a guy about sharing info/files from the map update, would provide some insight about an update procedure or hopefully a bootloader if its more than just maps.

 

Another thing I've been looking into is the emmc chip. There's a test header and pads next to it. If the cmd,clk,and dat0 can be located then a nand dump can be obtained. Probably would be encrypted but its a start.

 

On the opposite side of the emmc chip near the test header there are 6 large test pads that are exposed while the PCB is encased. Would make since if those were associated.

      Missing thrust bearing? And oil selection

      By Black02Silverado · Posted

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By revmanii · Posted

      So, lot's of googling and reading, and a trial fit found, that indeed they hit the newer fatter caliper. I did some re-testing today, and found just 3/16" worth of washers was enough for the wheel to spin freely. I added 2 more on each, and again it spun freely. Tested lock to lock with the 4 washers, about 5/16" not quite the 3/8" Im considering, but pretty close. No issues. I've been looking at the BORA .375" spacers and using extended lugnuts to get back lost thread due to the spacer. All the ET lugs I've seen are all .33" reach inside the wheel lug holes. For those that don't like spacers or think they're unsafe, I think it depends on what type of spacers you're using and making sure you get good quality hubcentric ones, and if you're using bolt on ones, regular mainenance, checking the spacer lugs. Not wanting or needing that much spread. Looking for the minimum that will let me run these rims and tires.  it does look to stick out a little, but I really want put these on. and use the stock all-terrains in the winter.
