It's in the Console, on the near the USB Port. Hard to see and have to push in to have it pop out!

 

Yep, when writing software you create lots of IF Do loops, etc. Some interact in a way not considered or every wanted.

Another fun "anomaly" I encountered in our work was by a friend who started in R&D about when I did in 1964. Good friend and about my age. He's an EEE (my name for an EE with a Masters.) My tech expertise was automatic welding processes etc. We worked together on a SAW control back when. Ted probably had more computer courses than I, which was as a Senior using an IBM mainframe and programing in Fortran! I moved on from a slip stick to a Ti-59 programable calculator than managed the filler metals and MIG shielding gases R&D Lab and Ted remained in the equipment design. I bought the 1st Radio Shake PC for a LAB project that came into OH (the store manager told me that as I always called because it was late.) 2K of memory and do your own programing as there were no canned programs in the mid 1970's. Recall when we formed a leveraged buyout of the welding business I bought and IBM XT and Okidata printer for my home office for $3500 1985 dollars! Last time I did any programming as spreadsheet, word processing etc programs were available.

Had worked with Ted when he developed the 1st microprocessor MIG welder in our industry and I had formed a marketing arrangement with Unimation robotics. Ted and their top engineer developed the communications protocol so they communicated with each other! A similar control was employed on two automatic Pulsed MIG welders a company making Stainless Steel food freezing belts used to make a spot weld on the stainless pin that held each line of belt links together. About every 400 to 600 welds the voltage spiked and burned the link. The production line stopped and links had to be cut and removed. Promised the distributor owner who sold the systems we'd get that solved.

Sent our best welding process guy to visit as sounded like a typical grounding problem with a moving part like this belt. It wasn't. I went to the equipment R&D lab and saw Ted had set up an automatic carriage system that went back and forth making the Pulsed MIG spot welds on a plate. He was able to duplicate the issue BUT had checked all his programing and said it just can't be happing. But sure enough every 400 to 600 welds it did. I recall saying, understand you can't fine it but can you put in a small detection program so if this "can't happen" tries to happen you block the high voltage spike? He yes and did.

Problem solved but he never found the original reason in all the parameters being controlled, pulse height, pulse frequency, low and high current, current rise rate etc. which combo caused that to happen!

 

Reloaded all my songs on a new high speed Thumb Drive to see if speed would help.

Decided to use the new GM NAV Card I purchased. It came in the Unlocked position!

I had moved the Tab in the OEM 2020 Nav SD card that came with my 2020 from the locked to unlocked position! Or I'm 90% sure it came locked! So looked and found a good pic of a 2020 NAV SD card posted by CJ8. It shows the Tab in the unlocked position.

Started the car and all worked fine, got music and No SD Card Removed message. Doesn't mean a lot, we'll have to see how often I get the message (hope never!)


I Thought My Original NAV SD Card Came Locked and I Unlocked It! But This Pic From CJ8 of His Card Shows It Unlocked. ???? Anyone have a 2020 NAV Card and can look?

 

I have read all the posts. I had never removed the SD card and have never tried to load music on it. The error message just appeared. I tried the lock and unlock, no change.

I received an offer for a new map upgrade from GM. I called and explained my problem. They said if it did not work, I could return it (normally not a returnable item). I just installed it and it seems to have corrected the issues.

Not sure if that will fix everyone, but it worked for me.

 

Interesting that you brought back this 2022 Thread. SD Card for Maps no longer an issue for 2024 and up. Corvette no longer has one! Have to pay Google ~$30/month to get their NAV. By the issue I and others started about conflicts on the Buss that carries lots of info at the same time in the Vette turned out to be my Flash Drive (you don't load music on the NAV SD Card they just communicate on the same Buss!

The great Tech that works on my Vette solved this on my 2020 C8 by 1st reloading the Infotainment software.. BTW same issue with GM Trucks and other cars that use the same Infotainment system. No help. BUT on the bottom of the GM Trouble Shooting steps another Tech had placed a note. It said IF the car is using a San Disk Flsh Driver that could be the issue. I asked why and he said we Techs often post info without an explanation because we have none. Just what we observe!

So I bought another high quality Flash Drive and it solved the problem! Here is my research as why, bootlegged, fake Flash Drives sold on Amazon:

Bought this quality but not as well known brand Flash Drive for Music and all started to work fine. Is now in my E-Ray!

My experience with parts copiers in my business, welding, reinforce why the leading brand would be the one copied! Parts copies are smart! We had the leading TIG torches and consumable parts like collets, collet bodies, gas lens etc with our Heliarc Trade Name products. By far the market leader. That was from the 1950s. When the patents expired parts copiers, copied and sold our products. They did not use our Heliarc Tradename as we had enough Lawyer's to stop that. But copied the profitable wear products like collets and collet bodies often made from inferior materials like plan copper versus the Beryllium copper or Chrome copper we used because the parts get hot! BUT they copied our part number which before computers always had few numbers and letters.

For fun I just checked a welding market leader, Lincoln Electric who didn't start selling TIG products until ~1990 because the founder JF Lincoln (who died in 1965) and his successor Irrgang who followed the Henry Ford Model Tee philosophy lower prices continually hated anything to do with industrial gas. They now have a full line, probably bought from China and note they still, like all others sell collets with our old part number 19N21 etc etc.

BTW we kept the high quality and the company was happy our products were copied! WHY?? Because their main and very profitable business was the Oligopoly Industrial Gas Business. Back then we had ~60% of the US Argon production. Sold ~30% ourselves and the remainder to the few other Industrial Gas manufactures. We controlled the price. Today two European Industrial Gas company's bought the US leading companies. They have ~70% of the Argon production (BTW Argon is the gas used in TIG welding and a majority of MIG welding.) Argon is very expensive and obscenely profitable for the gas companies. It's a byproduct of making liquid Nitrogen and Oxygen. Have to make those two gases, store and transport and sell distribute those two gases to afford to make Argon that is only 0.9% of the air. Yep our patent company thought more TIG torches in the market, the cheaper the better, more Argon Gas Sales!

Helps me do very well with my part time business selling products that reduce Argon waste in welding!

Yep buying from Amazon- be very careful!

 

@JerryU You're dating (not in that sense) me now. LOL.

 

I had this error on my GMC Acadia. The problem turned out to be a defective reader. Local dealer had to replace the reader, not the card. It was an actual defect. This was in my specific instance, but may not apply to all or any other.

The incident occurred when I ejected the Nav SD card and then reinserted it. No idea how it caused the reader to fail, but I no longer touch that thing.

 

^^^^
Not sure why my 2022 Thread has reappeared BUT worth reviewing again for some for another reason.
Turned out after many dealers had tried to fix card readers, replaced SD Cards with similar message to what I was getting (Pic below as shown in Post 1) in Corvettes, GMC's and other Chevy's with the same GM Infotainment system and getting the message if you search. It was NOT the card reader. It was the Music Flash Drive trying to load on the same Buss as the NAV Card when the car starts. I spent 4+ months chasing the issue, cleaning my Card reader contacts,, shimming the Card to get higher pressure on the reading contact fingers, chasing a lead (that helped) reducing the MB size of the songs another member showed worked for him. Since it was a ~30% issue when staring would think i found an answer- THEN NOT!

Turned out found by my Tech who had replaced the infotainment software that was no help, another Tech had put a note on the GM Service Computer troubleshooting page that said IF using a SanDisk SD Card could be the issue. As stated SanDisk is the Market Leader how can that be?? Easy I bought from Amazon! How do you know it's a "Real" SanDisk. You don't! Could be a bootleg copy and in my case that was the problem! Sure bootleggers are smart and copy the market leader!!

Just had an Amazon bought AA battery fail, on our electric activated (capacitance on off) kitchen sink faucet. Two of the 6 were OPEN. NOT low voltage or week 4 of 6 tested fine. It was open. At our retiree Tuesday lunch an EE from our R&D group who attends relayed what he found about Harbor Freight batteries. One brand was fine but the others had failures by Opens! In fact the two of mine that failed were made in Vietnam. So as companies switch from Cheap products from China to Cheap products from other countries expect they will have production learning curve issues! From experience with China, my SD Card could have been from rejected of SanDisk SD Cards that didn't meet the required minimum read rate MB/sec spec. When thrown out, picked up by a bootlegger etc.

 

I've never seen that on my 23 and I have a huge sd card with songs on it but it's not a cheap slow sd card so if bandwidth is the issue maybe it's the sd card with the music on it. The host communicates with every device on the USB buss but not at once...

In the Corvette there is NO SD Card for music. In the 2020 thru 2023 there were two SD cards. One for the Google Maps (updates sold by GM) and one empty required for the Cosworth PDR is so equipped. 2024 and later eliminated the NAV Card that was in the Console. Now only a blank one needed to record PDR info. As in 2020 that SD Card slot is to the left side once you open the glove compartment. Music as it was for my C7s was from a Flash Drive (also called Thumb Drive, Pen Drives etc.)

 

In the pre 2024 1LT cars without navigation the SD card slot in the center console could be used for music. I think it might be able to be used for music in the 2LT/3LT cars if you want to give up built-in navigation.

 

Actually, in a 1LT the SD card slot in the console was empty because there was no Nav, and could be used for music. But for the 2LT and 3LT you're correct.

Oops, RCKRLR beat me to it.

 

Sorry I meant usb storage device... dunno why sd was on my mind lol. Too many cars with different music storage devices.

@JerryU I was told by my GMC dealer that they had to do a complete checkout vs just replace the Nav SD card when that message came up OR if it turns out that he problem is not the card and is in fact the reader, the dealership has to eat the entire cost (Apx $450-$550 at the time, not the $100 upgrade charge) of the Nav Card.

Yep in the 4+ months I chased the issue some folks did have the reader replaced. Like many of my "tries" it 1st looked like it was working since the message only came about 1/3 of my starts. Other GM cars with the same infotainment system that were getting the message were the same. The fellow who said his issues was sol ed by reducing all Music to max 160

I'm sure there were other causes and fixes but for me, what my Tech found on the GM Service Computer, the note from another Tech, was my solution. Yep lots of Bootlegged "stuff" on Amazon. Can be SD Cards, Flash Drives etc. Leading Brand Names are ones they would logically copy. Looking for the lowest price, which can vary significantly for what appears like the the same capacity is one clue! That was my issue a Bootlegged SanDisk Flash Drive I used for Music. The Verbatim Flash Drive I bought solved the issue. Have not seen message once in my E-Ray in 15 months an am using the same Flash Drive.

 

Help
Purchased the 2025 update for my 2021 and put into the nav sd card slot. I get error card removed. Put original card back in and it was OK. Tried again and it said card removed. Put the original card back in and not it will not read the original card. Was there a specific procedure?

 

IIRC, a new SD map card needs to be installed with the lock/unlock slider set in the unlock position. The system needs to write to the card to activate it and lock it to your vehicle forever. The map card cannot then be used in any other vehicle. When I encountered the error message with the original, factory installed map card, I tried removing and reinserting with no effect. The dealer service guy told me on the phone they would need the car for at least a day to diagnose the problem. I went on e-Bay, found the new updated GM map card for my 22 C8, and bought it for about $40. It arrived a few days later, I plugged it into the slot, and the maps/HUD have worked perfectly ever since. Really, I figured it was worth $40 to avoid the dealer and worst case was a $40 loss.

 

I had this exact problem on my Acadia. I went to the dealer and it required a SD card reader replacement. Under warranty free, otherwise $500 out of pocket!!! It was during the first year so free, but never updated after that. Waste of $100. I use Google maps.

The problem was not the card(s). There is an obvious defect in the ecard reader design Hardware or software). It is probably due to the car VIN specifics of the software security to prevent owners from copying other owners newer card data. Thank you Bill Gates for software security nightmares..

 

5.5 years of ownership and I have yet to touch the nav SD card for any reason. I use Waze over AA just fine.

 

41k miles on my MY23 and my map works fine... I've never used Waze or AA whatever that is. Interesting this old thread keeps popping up.
