I have been getting a message on dash indicating that SD card has been removed. When I attempt to start navigation app, it gives message that SD card has been removed. I tried removing and re inserting the navigation SD card in middle console, but the error continues. I removed the music USB drive as someone had suggested but it didn’t make a difference. Has anyone encountered this and how was it fixed?

 

My wfes 2020 Acadia just had this issue. Dealer had to order a new SD card.

 

We have had several threads on this. The NAV SD Card needs to be ejected and re-inserted and that usually resolves the issue. Card resides in center console armrest above the USB ports.

 

I think it resolves it temporarily at best. Mine is acting up again

 

I have a 2020 Silverado and I go the same problem. I ejected the Micro SD and "locked" the tab on the card. I reinserted the card and I was able to get the issue to stop.

I did this multiple times with no result.

 

I did this too, but did not resolve the problem.

This occurs when the USB drive is streaming music while the NAV is initializing. It only occurs if you use high density music 320bps.

To follow up on my research I built 2 USB drives with music. The first drive has songs recorded at a bit rate of 160kbps and lower, the second has songs all recorded at a bit rate of 320kbps.

To make this problem occur you need to be streaming music from the USB drive to the Media app while the NAV is starting up.

I tested the 160kbps USB drive for 3 weeks without a failure. I then replaced that USB drive with the one recorded and 320kbps and the failure occurred the second time I started the car.

The obvious conclusion is that the NAV SD card and the USB media shares the same data bus, and with the higher bit rate music playing while trying the read from the NAV SD card creates contention on the data bus that the SD Card control software is not able to recover from thus the NAV SD Card Removed message.

2 Friends of mine with C8s have tested this with the same conclusion. In one case the dealer ordered him a new NAV SD card, and in the other the dealer wanted to replace the SD Reader in the center console.

Neither of these will fix the problem and this idea of re-seating the SD card is totally ridiculous. It just give the dealers a quick exit from having to deal with this problem.

 

@zo6devilcar Glad you posted this--great research! And it happened to me today; and only then did I find and read your post.

Here's how my experience went down this week. Got the car in December and had not driven it much while waiting for my PPF install. While my detailer had the car, I ripped several CDs into 320 kbps FLAC files on a USB drive using MS Windows 10.

When I picked my car up Tuesday and inserted the USB thumb drive, the infotainment system repeatedly indicated no drive inserted. After several failed attempts, I just let it be. Then a couple of car re-starts later in the day it then recognized the thumb drive and worked fine. Oddly, on the same day, my Nav wanted me to again accept all the new user agreements, as if it were the day I took new delivery. I thought it was due to the car having been on the battery tender for a couple of weeks.

Today, while listening to my new USB tracts, I selected the NAV app and got the error message below. Pulled into a parking lot and searched and found this thread. After inserting and reinserting the Nav SD and thumbdrive, I was unable to get the Nav app to work. Then the USB could not be located. Tried removing the Nav SD card again but couldn't get it to pop out of the slot. Also, I stopped and restarted the car with no effect. I then unplugged the USB and drove on.

About 15 miles later I parked the car. Returned in about 20 minutes and the NAV opened and worked.

I have not had the opportunity to try, but I wonder if just switching to a non-USB audio source before activating the Nav app, then returning to the USB audio will allow both to run concurrently. Anyone tried this?

Also, if you have re-ripped your tracks at 160kbps, have you noticed a discernable loss of audio quality through your C8 audio system? Just looking for work arounds to having to re-rip my CDs and possibly sacrificing audio quality.


Nav App Conflict with 320kbps USB audio

 

Have had a hard time getting the Nav app to work. Kept getting the screen error posted above. After two days and multiple car re-starts, I decided I would try removing and reinserting the Nav SD card. To my surprise it was ejected. I reinserted it and the Nav app booted up.

Can the SD drive self- eject the Nav SD card the way a PC ejects a DVD?

 

I've found that I have ejected my nav card while in the process of getting in/out of the car and thus putting in /taking out my cell phone (thats plugged into the center console usb port for android auto n charging). the xl size phones seem more prone to accidental pushes

 

Interesting. A couple of weeks ago I tried to remove it to see if I could correct the SD card missing error, and I couldn't get it to eject.

 

Yes, by rebuilding my USB drive with 160kbps music the problem has never reoccurred. The audio quality doesn't seem to suffer using the lower bit rate. I also use spotify via blue tooth.

Hmm, my "No SD Card Installed" appears to occur randomly. Never saw the problem until I stopped using the FREE XM when it ran out and now use the USB with ~1000 songs I had in my C7s. Just checked and most songs are 160 kb (a few less) BUT some are higher like 192kb and 262kb. They play in shuffle mode so wonder if I stop when a 262kb song is playing and it restarts when the car starts IF that is when I get the message???

Should I buy some software to change the bit rate?

PS: Found some free Open Source Software Audacity, and converted all to 160 kbs or less. So far (a few hours) it's working! We'll see it that is the final solution.
