Good morning folks!  Got a call from my service advisor at my local GMC dealer that there was an infotainment system update available to download.  I asked him if it could be completed OTA (over-the-air) as I hadn't received any automatic updates (nor manually either).  He said that it appeared, due to the size of the update, that it would require the vehicle to be brought in for the service.  He admitted he could be wrong about getting it OTA, but this was his experience with it (see below).  Brought the truck in and was heading home 45 minutes later.  No issues with the update...so far!  This is a long post!

 

I subscribe to a website called RepairProcedures.com and was able to look up the software update to see what was...well...updated.  Here's what I learned:

 

  • This update is for vehicles equipped with infotainment systems ROP codes IOS, IOU and/or IOT.
  • The reason for the update was to fix software-related anomalies.
  • A new radio software update, version V158, was released to service for vehicles equipped with Infotainment system RPO IOS, IOU or IOT. In addition to providing general robustness and stability enhancements, this update includes all enhancements from previous software version releases (i.e. V152, V155, etc.). This update can occur remotely through in-vehicle prompts from the radio display. However, some customers may decline the vehicle update, or the update may be unsuccessful. Along with the vehicles mentioned above, vehicles in unconnected markets, and fleet customers may need the dealer to reprogram the radio with the new software package.

 

V158 Most Notable Improvements and Fixes Include:

 

Bluetooth

  • A blank or black screen may occur when making a slight adjustment to volume knob

Camera

  • Automatic Park Assist (APA) may not switch to the 360-degree camera view at times

  • APA may not launch.

  • Note

    It is normal, design-intent behavior for APA to not launch while 360-degree view is active. This fix will not change that.

Energy

  • Improves graph format in Energy app

  • After pressing the Stop Charging and Unlock button the screen may not display a message that charging has stopped and that vehicle can be unplugged

  • Charge completion time may display in an incorrect color

  • If a user attempts to select Charging Options while the vehicle is being driven, it does not display feature unavailable while driving

  • After setting “Stop Energy At:” the Rate Schedule Type may not change

HMI

  • Non-responsive touch condition that self-recovers after 3 minutes may occur after installing any app

  • While downloading an app the characters in notification that indicate time remaining may be incomplete, the lower portion is missing

  • While using wireless charging and after ending a phone call CarPlay will show the phone is still charging but the Home screen charging status may not match

  • Bluetooth phone signal and battery icons may appear and disappear intermittently when Performance Data Recorder (PDR) is active

IPC Interface

  • A portion of the Press Handset overlay message may be missing in the IPC

  • After merging two phone calls, the IPC may display a blank overlay box

Navigation

  • When Head Up Display (HUD) transitions from Next Maneuver overlay to Lane Assist the display may flicker

  • After changing Location Services from Off to On, the Traffic Flow feature may not become active

  • The navigation interface may change to 2D and be inconsistent with Porch view display after sliding on the Destination card

  • A speed camera icon may intermittently disappear and reappear on the map

  • Improve navigation map data SD card VIN binding process

  • Improve, but not yet eliminate, an SD card removed message that may occur only on startup when using a customer’s User Profile

  • The Speed Bump Alert may disappear at the beginning of route guidance on certain destinations

  • Voice Recognition button may appear in regions that are not supporting the voice recognition feature

  • Charging station POIs may be displayed on the opposite side of a roadway

  • SD Card error message displayed with 0x8 error code

  • Predictive navigation estimated time of arrival (ETA) appears on radio, but may display dashes on instrument cluster

  • Navigation route may not start from Main screen if user selected “xx minutes to Home” by steering wheel controls in the clusters Navigation Menu screen

  • Alerts for Charge Vehicle Soon and Charge Vehicle Now may not appear in the radios Navigation app while the vehicle is being driven but do appear in the cluster, and Charge Vehicle Now does appear in radio if vehicle is stopped

  • (Non-GMNA) When GPS signal is blocked (example: parking structure) the dead reckoning may not go active causing vehicle to have to reacquire GPS location once leaving the structure or area that blocked GPS signals

Settings

  • Door Lock/Unlock customization settings for All Doors or Driver Door Only may not be retained

  • The Collision/Detection Systems customization settings may be missing some options after changing languages

  • If in the Settings app when ignition is cycled off then on, the Settings page may be blank

  • While scrolling in the Climate and Air Quality interface settings the display may flash

System

  • After using the Infotainment Control Switch in the center console to change the station in the Tune screen, any input into the radio may change the station again. Example: Pressing the Radio button on the control switch to return to the Audio page or shifting to Reverse to pull up the rearview camera could cause the station to change again

  • When attempting to adjust Lumbar position a message that “Massage Seats Unavailable” may appear for one to two minutes after startup. The memory seat function will still recall Lumbar settings

  • At startup, the display may freeze on the myBrand splash animation screen. A radio sleep cycle recovers this condition

  • Improve ethernet DTC diagnostic algorithms for U1008, U18B4, and U0078

Trailering

  • When launching Trailer app, some trailer profiles may cause the display to go blank then return to Home screen

 

I don't know if any of you are affected by some, or all, of these "fixes", but it certainly cleared up a couple of issues I was having with the truck.

 

Cheers!

While in for other issues I complained about my radio function and they did an update about 2 weeks ago. Prior to the update my radio would turn on but be at zero volume. It would also automatically connect to my phone and auto-play whatever book or podcast I may have been listening to. It wasn't earth-shattering but it was annoying. Fixed that.

Would it be possible to add heated/cooled seats in my 2014 if I were able to come upon a wrecked vehicle for the parts? I have heard the computer in my truck wouldn’t let it work, but if anybody knew for sure I thought you might. And if I need a harness to make that work.

Does anyone know of a way to watch videos from your phone on the screen. On my 2017 I was able to have the radio module unlocked to be able to watch videos and use the nav while driving. Can this be done on the 2020. By the way mine successfully updated over the air

I have an appt to go in and hopefully they know it is an update and can update it manually.  Would be nice if GM would allow up to update it our selves...

 

Got an update that failed and I have not display at all update failed...Only displays a command window.

    • If everything checks out at the MAF, then the MAF is BAD, new or not.   You don't need a signal generator to troubleshoot this. PCM needs ALL powers and ALL grounds able to light a halogen headlight bulb - if it can light the bulb bright, then the wiring is good enough to run the PCM.   Best thing you can do for yourself is spend some time here: scannerdanner.com - Check out all his YouTube videos on similar issues. If you decide to subscribe it's the best bang-for-buck ratio in the automotive world, hands-down. He's got TONS of free vids on YouTube, too.
    • Yes, I used my multimeter to probe all of the wires at the MAF, both with the sensor connected, sensor disconnected, key on engine off, key on engine running, etc etc etc. I probed all of the wires again at the PCM, at the connectors, etc. All voltages are what they should be according to the service manual/wiring diagrams. All grounds are good, less than 20 millivolts from the battery negative under load. Both at the connector of the MAF, at the PCM connector etc.      I know this throws a pretty big wrench into things, but this truck was acting up before the swap. I don't have very much information, if any on what was causing it, but if you cleared all of the dtcs it would do the same thing where it would crank, fire, then die. And it would do the same thing a dozen or so times, and eventually it would start and run, but the difference is that it would run and actually be drivable. Whereas now if you can drive it at all, it goes into reduced power mode almost immediately, and even then it's not running correctly. When you come to a stop at a light it stumbles down to for 500 RPM before catching itself and returning to the smooth idle. And if you go more than about 50% throttle then it immediately goes back to doing the misfire thing.    Like I said, I know that throws a wrench into things, and unfortunately I was not able to pull any data or anything like that before I did this work, so I don't have much to go on.    I'm trying to not fixate on one particular thing as the cause of the problem, but it seems like all avenues are pointing me towards the PCM. Like I said I have tested the wiring extensively (see above), and during cranking the sensor does produce seemingly legitimate values at least according to my multimeter, but as soon as the engine fires those values quickly descend into gibberish. I've tried it with multiple different known working sensors, I have done literally every test I can think of multiple times on the wiring (probing the signals, probing the pins with the sensors unplugged, probing the pins at the PCM, voltage drop, voltage drop under load, continuity, ohms, and double-checking everything against the wiring diagrams/ proper values in the service data.)    Another thing that pushes me towards a possible PCM failure is, I have noticed in troubleshooting a little bit taking a break and coming back, that when I leave the truck to sit for a while and cool off, it starts and runs smoothly when I first start it up. However once it warms up. It starts having problems. For example, when I went out to the truck this morning after it had been sitting overnight, I was actually able to drive it down the block. And then once I got on the throttle a Little bit after going about a thousand ft, it started misfiring again. I pulled it back into the driveway, shut it down, and started it back up. It idled smoothly. As soon as I touched the throttle it did the misfire thing again. From then on as soon as I started it it would misfire. I shut the truck off and went to go get a coffee and do a bit more research. When I came back out I started the truck up and it immediately went into the smooth idle. After a couple of minutes of playing around with it, it would not idle smoothly anymore. Let it sit a couple of hours, rinse and repeat. This makes me think with temperature change something is going wrong inside the PCM. I have the PCM out of the 2007 donor vehicle and I'm thinking of getting a one-day subscription to the ACDelco programming service to try and program that and see if it helps.   Like I said, I'm really trying to not fixate myself on one potential cause, but it seems everything is pointing me towards PCM failure. I would really like to try to confirm that, but unfortunately I don't have an oscilloscope or a signal generator to do the GM service procedure where you feed 5 khz into the signal pin. 
    • Ahh, sorry about that - I got some bad info. Newdude is correct. That's what I get for working 13 hours straight ... on my "vacation", lol.   Should've checked the files I had instead of the internet.   Anyway ... this is GREAT news, since this would've been an absolute friggin nightmare to get working.   I don't think the lack of VVT is causing this - you've got another issue. Wiring, I'm betting.   I'm telling you right now, your computer isn't bad. If it worked before the swap, it's working now. You need to do some more (better) diagnostics and figure out exactly what you're missing. Did you test every wire directly at the MAF? Have 5V reference? Ground? If you're reading ZERO g/s, your Hz isn't much use - it's going to be the wrong value anyway. The MAF is not working, and you need to find out WHY.   I got this off the net, so VERIFY first: Pin A: Black (BLK) wire, Circuit 552, serves as the Sensor Return (Ground).  Pin B: Tan (TAN) wire, Circuit 472, carries the Intake Air Temperature (IAT) signal.  Pin C: Yellow (YEL) wire, Circuit 492, is the primary MAF Sensor Signal output to the PCM. Pin D: Pink (PNK) wire, Circuit 339 or 539, provides Ignition 1 Voltage (Power).  Pin E: Tan/Black wire, Circuit 552 or similar, often associated with the Intake Air Temperature ground or signal return.  Global-A list: https://postimg.cc/KKJnQC85    
    • Correct....the end user can't reach to Realtruck directly like they can if they purchase a Bak, Undercover, etc...  It has to go through a dealer.
