My 2020 did not come with an SD navigation card.  Dealership told me I could buy one and utilize the nav system "offline" (no subscription services, no data plan).  Have not found good info online so far that says the same...  Can anyone confirm?  If I buy  a card and plug it in will this work?  Where do I buy the card?

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

My wife had a NX200t F Sport and had nothing but problems with her radio, traded it and got an Acadia Denali. All brands have issues

I am having the same problem with my 2019 Colorado ZR2, and haven't been able to use the Navigation system  properly in months due to this!

 

Corporate had me bring my truck in to a dealer for a software update; Version 807, which they stated will be released as an over the air update in January.

 

They stated they were absolutely confident that this would solve the problem, as the software was created to solve this particular problem.

 

Well… guess what… the problem remains!

 

Beyond upsetting that after all this time, and the assurances provided, that there’s no resolution in sight!

 

Anyone else have any news to report?

 

Anyone find resolution? If so, how?

 

What has corporate / your dealers been telling you?

Total BS.  If you have the Nav system, you get a card.  Note the cards are serialized to the truck, so you can't take one out of a buddy's truck and swap it to see if it works.  Call you (idiotic) dealer and explain to them that you were not given the SD card for your NAV system.

Had this exact same issue with my new 2020 AT4 (CarbonPro) diesel.  Would not work while at the dealership, but I drove 500 miles to get my truck (and it was Saturday Evening) so I made the trip home without NAV.  After I got home, I was troubleshooting (seeing if other connections inside the console worked) and after plugging a USB cable into the jack next to the SD slot, it started working.  This was the first time the SD card ever worked as it then began to "initialize" the card for the NAV system.  Figure it was a loose connector on the cable or the jackplate.  Every once in a while, I'll get a "SD card removed" error after I'm messing around inside the console, so there's likely an intermittent connection issue there.  I'll have a look at it when I get around to installing my AutoStop Eliminator.

 

Anybody seen a TSB on this?

My finally got fixed had to have take it to the dealership and they had to download a software update to the radio that The dealer could only get. It took two days for them to get the software to download even to their computer. It’s been working for me since it only messes up sometimes but it fixes itself.

what software version(s) does your system report now?

Posted

After researching the Nav upgrade for my 2020 Silverado 1500 I had my dealer order the card and they're going to install all the software and updates when it comes in.

I could have saved a few bucks by ordering it myself but this way their warranty covers it.

I've read about all the problems you all are having so I'm aware things might not all be rosy for awhile so we'll see.

 Any updates on this anyone?

 

I'm still having the difficulty with this.

 

Now on Version 807.

 

Thanks. :(

Bummer, I got the updates last week, and after a couple of days, I'm still having all the same crashing issues too.  so it would appear the update didn't fix anything.

Is the lock position on the nav SD card switch UP toward the top of the card or DN toward the contacts?  I want to try this.  Thank you.

Hi Andrew,

 

So your SD Card Removed problem has been resolved?

 

Can you please give us a break down of your whole matter and which vehicle you have.

 

My 2019 Colorado ZR2 had ZERO problems on what I believe was software version 509.

 

Did an over the air update at home to 805 and the SD Card Removed error started happening.

 

Often had to drive without NAV, which was annoying, as I specifically wanted a NAV truck.

 

Dealer did an update to 807 and the problems became worse with the system freezing, going black and restarting frequently.

 

They now want to replace the SD Card receptacle (jack/cable).

 

Can you please give a complete, detailed break down of what you did and how you got them to finally fix yours.

 

Do you have any problems at all now with your infotainment system?

 

I'm concerned with what you wrote: "it only messes up sometimes".

 

Please explain.

 

Thanks so much.

They replaced the sd card first, reader part, the usb cable, the whole radio unit, and finally they called GM and got a software patch that the dealership had to download it. It took them two day’s to get it to download to their computers. After the patch update it was fixed. It’s been okay every since. At first sometimes it would still pop up the error message but it would fix itself and work right then. Last week the only random thing was my backup camara had a blue screen on it. But it finally came back after it sat awhile and worked. Your best bet is to take it to a dealer and have them call GM and have them install the patch for the radio system.

    • There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.                  
    • drive the truck back to the dealer and complain that the button works.

    • I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip. 
    • Fuel mileage?  That's all how you use your right foot.  Exhaust will give you sound.   Stock exhaust 5.3 is 2.75" diameter piping.     If the truck is nice and worth putting some $$ into it, I'd go for a Corsa catback.  I had one on my 2019 old body 5.3 and it was just perfect.  Zero drone, just driving around and cruising on the highway you'd think it was stock, but when you opened it up it was like a Camaro with the factory dual mode.  Corsa bumps their catback to 3in diameter.
