I tried that, nothing.  I took it to the dealer, they had to order a new SD card reader.  Hopefully that does the trick.

The dealer replaced the SD card reader today, it seems to work fine now.  We'll see if it last.....

I know this topic is a month old, but my AT4 that I've had a week did the "no navigation/SD Card Remove"thing tonight.  It was working and then stopped in route.  On the way back, after the truck being off for maybe 5 minutes it worked fine.  Hopefully, this issue doesn't continue.  Everything else has been great, including the navigation when it works.  

 

I was wondering if anyone else is still having this issue or if they have fixed the problem for the most part.

Thanks, I haven't had any issues since, hopefully it was fluke.  I installed a console lockbox earlier that day perhaps I jarred something.

Well it happened again, the navigation wouldn't work, with the message that the SD card had been removed.  Also as someone else mentioned the USB ports (all four in front) stopped working.  This all occurred on start up this time, last time it was while I was driving.  

 

I drove down the block and back and turned the truck off.  Waited a minute and turned it back on and everything, navigation and usb worked fine.  I'll call the dealer on Monday and see what they say.  Hopefully this isn't one of those things that is hard to trace.  With the USB charges not working, it appears to be more serious than just the SD card needing to be replaced.

My AT4 is doing the same thing with the card error but I have also noticed that the entire media unit is inoperable. The USB ports and aux jacks are not working either. The entire media port is defective. Need to contact the dealer to fix I only have 400 miles on it!

Brought mine in for this issue about two months ago.  In the end, the dealer replaced the card, card reader, whole radio unit, and the USB/USB-c plug under the radio.  They managed to finally fix it but it took two weeks for ordering various parts and stuff.  Just for fun I asked what they do if all this didn't work.  They said they still had one more option which would be to put in a new wiring harness.  Luckily, they didn't have to do that.... yet.  No problems now for two weeks now.

Been having this issue still wondering if your problem has been completely fixed???? Or if you still have trouble with yours?

Ever since they replaced that usb-c plug under the radio it has work fine ever since.  I believe there should be a tsb on it.  Time to schedule your appointment!

Just had this happen to me when i turned the truck on today to go to work. 

 

I reseated the SD card. Nothing. 

 

Stopped on the side of the road and turned off the truck for 30 seconds. Nothing still. 

 

I got to work and went back out 30 minutes later. It restarted the truck and it booted up. Although it took about 3 times as long to do so but it did it. 

 

We will see how it continues going forward.

I would call Chevy and complain everyone needs too! They don't take it serious enough. They replaced the charging cord today and it did it again after it was turned off for a few minutes.

Very strange the fix for mine was to pull the SD card and slide the side tab to the UNLOCKED position. Previous posters said it should be in the LOCKED position? Only had the truck a few days so not sure if it is really fixed or not...........

Same thing on my 2019 with 800 miles on it. GMC needs some quality controls at the plant. Now I remember why I have been driving Lexus for ten years -never a problem. 
 

dealer said that they will order a new card reader but don’t think that’s the problem. I guess I don’t have nav in my $70k vehicle why they try to figure out what their problem is. 
 

**update: flipped the switch on the card and now it works. Not going to tell the dealer just in case but Nav is working again now

Did you lock or unlock the card?

Mine has been at shop for three days, 500 miles. Dealer is supposedly replacing reader. Not happy

I have had my truck in 4 times for the sd card error.   They replaced the card, reader, checked connections, and just did software update.   Guess I have to wait and see

    • Would you supercharge the 6.2L on a 2021 GMC Yukon Denali XL with ProCharger?.... 605HP is the stated number without going crazy - it's not the LT4 682HP package, but I'm tempted to install it... This vehicle was ... not... recalled on the engine swap - but I don't really know if that means ...don't do it... or do it;)    Maybe i should start a prediction market pool on it in case it blows up;)   Any thoughts appreciated - I already OWN the supercharger - stopped the installation when the recall was announced and now it's taking up space in storage until I can solve an electrical issue with the vehicle...  4th GMC suburban-equivalent truck - I like them a lot - when they don't a) discharge their batteries randomly, or b) throw a rod at highway speeds;)
    • We tested the sleep mode with an ammeter in series with the negative battery terminal - 30amp fused - so we do know the actual shutdown and non-shutdown current draws and timing of the shutdown sequence.  We just have no protocol information to determine what module is issuing the network keep alive.  
    • TrueBlue...Even if you don't have that info stuff displayed, If Mr. Computer thinks there's something you should know about, it will pop up a warning message no matter what else is being displayed. I keep the speedometer displayed all the time, yet the brake pad message pops up anyway.
    • BTW, the 11.5amp draw is all the usual systems active - it's not a single draw - that's the "we're all awake" state of the vehicle - forinstance if the power steps are actuated, the draw will spike to 22amps for that operation.  when the battery is disconnected and then reconnected, the vehicle shuts down that one time only - and we see a 10-15minute progression down 11.5  10.5  9. 8 6. 5. 1.6... 500ma... and then off to sleep at 40 milliamp... as expected.  So we know it's a module that is simply refusing to allow the SDGM to proceed to the sleep state.  We do NOT think it is the telematics VIM module - since we already duplicated the problem with the "VIM bypass" solution installed (we reverted that since it also disables the gmc app - but it does not appear that the telematics system is the culprit).  We've replaced the rear heater control module, tested without the wireless charger, and the other modules on CAN Bus 5 - but still something is keeping us awake and removing X2 from SDGM allows sleep to proceed.  We cannot diagnose from OBD since OBD drops off at about the 9volt level in sleep mode and we can't communicate with the vehicle - also we can't trace the SDGM internal packets from the OBD side - we have Autel Ultra.   Any ideas on why disconnecting X2 would allow sleep to proceed appreciated.  This is no longer a repair situation - this vehicie is simply unusable in this condition and NOBODY at GMC Dealer can even understand what it is doing.  This is crazy.  We made these systems too complex and now we're paying the price.
    • Did this ever get solved?   I'm chasing 2021 Yukon Denali electrical issues - vehicle will not enter sleep mode - we can disconnect and reconnect the battery and it will sleep - but that's likely because we powered down whatever module doesn't correctly sleep.  once we start/accessory the vehicle and turn off, it will stay at 11.5 amp draw with something keeping the SDGM alive - it appears to be activity on the X2 segment, specifically CAN FD Bus 5 - but we don't know which device and we think we've already isolated all of the devices on that segment - so what keeps the BCM and/or the SDGM alive is unknown.   I don't yet have a packet trace from CAN 5 (and since this Global B we might not get much info from it) - but the vehicle has been down for 8 weeks and previously GMC Dealer was unable to resolve "kills battery" issues with this particular vehicle - so I'm at a loss - it seems to be beyond local repair capabilities - and the number of "telematics keeps vehicle from sleeping" posts indicates this whole architecture has major issues - I hate to say it, but we might have to install a battery cutoff switch on the front grill - one of those red boat switches - to turn off the vehicle.;)  Any pointers appreciated;)  I just bought a CAN FD interface and I'm planning to try Savvycan and Peak Can SW to triage this further.
