SD Card Removed Nav error?

2019 Sierra Denali Ultimate.  900 miles.  Truck is great.  Love it.  However after 2 days the Nav started acting up and now doesn't work at all.  I get an error saying the SD card has been removed.  SD Card is perfectly fine and in place.  I've tried reseating, rebooting multiple times... nothing...  I've also noticed the USB plug in the center console right next to the SD card slot does not charge anything.  I'm suspecting a loose connection or bad wiring harness. I've checked the connectors directly behind the card slot and reseated them but no dice.  Where does the other end go? Behind the glove box?  Not trying to tear everything apart but it is annoying.

 

Anybody got a fix?  Really don't want to take it to the dealer and wait around while they figure it out if I don't have to.

 

On a positive note as a result of this bug I've discovered Android Auto and love it.  Almost better than the infotainment system itself!

Any updates on this anyone?   I'm still having the difficulty with this.   Now on Version 807.   Thanks.

Evidently the SD card must be "Ejected Properly" here's a link explaining what's going on and how to fix it...     https://gm-techlink.com/?p=13677

Yes. My AT4 did the same thing last week after a software update. It did it a couple of times in one day, but hasn’t happened since then. ??‍♂️

So now the Nav suddenly works (not sure why/how) but the check engine light came on.  I did unplug the wiring harness behind the glovebox for second but that's it.   Fix one find one...

Update:  Everything works now. Truck sat overnight and check engine light is off and nav continues to work.  I'm thinking the reset of the power to the system did it when I unplugged the harness.

There is a software update for the SIM card I believe, Also there is another fix, take the card out and make sure the little side button on the card is in the "Lock" position.

My 19 Denali had intermittent NAV  Error  SD CARD missing.  It would show the error and next day would start working again.  Talked to dealership several times about it but usually when at the dealer it would be working properly.  It finally failed completely and dealer got the chance to see the error.  GM had dealer send cable to the SD card reader unit and SD card reader unit back to engineering.  Cable and reader were replaced and no failures since.

I had my AT4 in for repair on this and the software update was not enough to fix. Dealer swapped out the SD Card socket due to reports from GM that *some* were fitted with defective SD card slots on the assembly line. If you still have trouble, have them check. the socket.

My Denali displayed the same message a few times, then it just went away.

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.

At 200 miles I got an SD card error and navi didn’t work. Dealer replaced the SD card and navi worked until 1500 miles. Now it says SD card removed but it hasn’t been removed and navi does not work. I guess I’m back to the dealer.

Take the card out and put the slide to lock, reinsert card and see if that does the trick for you.

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

      Gas Prices

      Can ask that about a lot of places.   Holiday sells 91 for $1 over 87 octane. BP 93 is 80 cents. Amoco 93 is 80 cents Kwik Trips is $1.20 for 92 or whatever they have and $1 for the 91.   I know that this is not exactly same as what you are saying with the premium to premium debate of those two stations but why is there such a difference. Top Tier this and that, it's all BS. All the fuel comes from the same damn refinery, so give me a break.

      Why does Mobil Premium cost 90 cents a gallon more than Shell Premium when their regular offerings are but pennies apart?

      Was all the way down to $3.69 a gallon but then jumped back to $3.99 just because for some reason.   Diesel floats between $4.80's to $5.10ish a gallon. I even saw Diesel #1 for $6.09 today but nobody in there right mind even buys that in the summer.

      OTA updates and radio still cuts out

      By Coastie05 · Posted

      Mine just keeps lagging or getting stuck on the reverse camera. When I turn off the truck, get out, and close the door it will still stay on. It’s very intermittent and I would not be able to duplicate the issue.

      Gas Prices

      I was checking out fuel prices at my farm fuel retailer at their pumps and yes the farm price is a bit lower than the non dyed fuel and was glad to see that the regular farm gas price has dropped a lot from what it had been but what blew me away was the price of diesel as the spread now compared to before the prices went up earlier in the year, diesel was actually slightly lower than gas which was a switch from the theme the last number of years. However that sure isn't the theme lately and definitely not right now. The prices I will post are not from that retailer but just looking at gasbuddy for the main city in this area and instead of posting the lowest price someone found I will list the higher price ( and that may not be the highest price, just whatever someone posted on gasbuddy ).   So regular gas and there are a lot of stations listing the same price for regular is 1.68 a liter, premium 2.00 a liter. Diesel 2.03 a liter for a top price I saw on diesel.   Figures out to 6.36 a us gallon Canadian funds for regular and 7.68 for diesel. With the US exchange rate it would be 4.58 us for regular and 5.53 for diesel.    Thought I would figure that out to get a picture of what it settles out like compared to various US prices and its about the same as the current price in Fairbanks AK as Anchorage tends to be lower. So yes, these would be the prices and higher along the way on the Alaska highway where they know they have a captured market !, for fuel prices for those beginning the long drive back to the lower 48   The problem is our Canadian dollar and going to the states that have the high prices, boy do we pay then !
