Has anyone successfully gotten video to play on the ceiling drop down monitors through a USB stick? I was under the impression this was possible but I haven't been able to get anything to work. The DLNA system is flaky to say the least and not exactly easy to setup with iPhones.

 

I have formatted the USB stick to multiple drive formats and tried MP4s that are h264 encoded, mpeg4 and mpeg2 encoded. So far, nothing works. The center console USB ports don't seem to want to recognize anything despite showing up in the rear entertainment menu. iPhone will play music and audio but that's it.

 

Thanks all. Sorry if this has been covered. I've been searching the forums but haven't found an answer. And GMC will not define what the system does or what "compatible devices" are. Aggravating.

I have connected USB flash drive to the rear screen, and I have successfully used DLNA.
For the USB, you MUST connect the USB to slots at the back, not at the driver centre console. All control will be from the rear.
For the DLNA, you must download the media you want to play on you IOS/Android devices and search AppStore/GooglePlay for DLNA apps. I have used TV Assist (by e2eSoft) on my iPhone and it works perfectly.

Thanks, Sarncan.  
 

Can you tell me what format the USB drive was and what video format you were able to play on the USB stick? I have tried FAT32, NTFS, MAC Journaled on the stick, h264 mp4, MPEG 2 mp4, MPEG 4 mp4... nothing has been recognized. 
 

The DLNA has worked but the connection has been a little flaky. I think I had better luck with TV assist than the other apps. 
 

Thanks again.

Great. Going to give all of this a shot. Thanks again.

 

Side note: was at the dealer this morning picking up a few things and talked to their parts/expert. He said he tried for four months to get it working and couldn't. Crazy.

I would say it is definitely the media conversion. Just use the website I’ve provided and use *.mp4 format and hopefully it will work. If not, try different USB 3 flash drives, but I doubt that it was the problem, because I previously used USB 2.0 without issues.

Update on all I did here:

 

The USB 3.0 flash drive I was using wasn't liked by the system. To mix things up, I put an SD card into a USB reader and plugged it in and it liked it. I was a bit surprised. I grabbed a USB 3.1 reader formatted at FAT32 and that worked great. Seems to like a variety of codecs but sticking with H264 MP4 seems to be best.

 

Thanks again for your help. Much appreciated.

Great news, so everything is working fine now?

 

And what I understand is that the problem was from the USB flash drive itself, right?

The issue was with the USB drive which is weird. I tried a few different drives that were USB 2 and USB 3.0  at FAT32 and they were not working. When I tried the SD card through the card reader and it worked, I figured it had to be a USB protocol thing. The USB 3.1 drives worked. Odd that it would be that picky but it's not exactly a mainstream system. All of these car systems are finicky.

No problem.
It is really weird that it is so picky, but at least glad that it finally worked well.

This video solve your problem with video play back on USB.

Link to video: 

 

Video must be MP4>720w x 300h>25framerate>1500Kbps bitrate

 

Videos play perfectly on both front and back video players.

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

      By revmanii · Posted

      The BORA 3/8" spacers arrived yesterday along with the extended lug nuts. I got the front wheels changed out today, but was overheated and covered in sweat so bad, I figured getting both front wheels done was a win, and took a cool shower. Hopefully, I'll go out tomorrow morning before it gets into the 80+ temps and do the backs. After getting the first wheel snugged up, I backed out one of the lug nuts then hand turned to count threads. I believe I stopped counting around 12-13, so I think I'm good there.

      2027 GMC Sierra: Official Discussion

      My fullsize truck is averaging over 26mpg so I'm pretty happy with the increased fuel economy targets. When I had my gas Silverado (2020 5.3) it was averaging 21. Again, for a fullsize truck, that's very different from the 12-15 these things used to get 30 years ago.   Whine all you want, increased MPG is a good thing.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That is a fair point, and I think an OBD-first proof is probably the right next step. I agree that the value is not the hardware box by itself. The marketable part would be the software: always-on capture, baseline learning, event reduction, system-specific reports, and alerts. Also agreed that if an OBD device is always plugged in and has local storage, it should not miss the event in the same way that a scanner plugged in after the fact would. The only thing I would not want to assume yet is that an ELM327-class device gives all the late-GM data needed at the rate needed. Standard OBD live data, DTCs, freeze frame, Mode 6, VIN, and calibration information are definitely the right starting point. GDS2 also proves that a lot of useful ECM data can be viewed through the DLC without needing a DTC first. The question I need to test is whether the data needed for a useful GM V8 event report is actually available through the DLC, and at a useful sample rate: - misfire counts / roughness by cylinder - AFM/DFM state - oil pressure and oil temperature - fuel trims - voltage / reset context - U-codes and communication events - calibration / software information - whether these are standard PIDs, enhanced DIDs, Mode 6 data, GDS2-only data, or not available So I think the right benchmark is: 1. Build the OBD-only version first. 2. Keep it plugged in and logging locally. 3. Compare it against GDS2 / freeze frame / HP Tuners or another higher-end logger. 4. Measure which parameters are available and at what update rate. 5. Only justify ECM-side hardware if it captures useful evidence the OBD version cannot. So you may be right: the consumer product might simply be an always-plugged-in OBD event recorder with much better reporting. A question for you: when you say ELM327 devices can already deliver all the data needed, do you mean generic OBD Mode 01 data only, or GM enhanced data as well? For a useful GM V8 report, would generic OBD data be enough, or would you expect the tool to include enhanced items like misfire by cylinder, AFM/DFM state, oil pressure/oil temp, U-codes, and calibration information?
