When I start using my navigation system, this message pops up all the time and I don't know why. It says "Nav SD Card Message.  Once initialized, this Nav card can only be used for navigation in this vehicle."   Then you would press the CONFIRM button and everything starts to work. But why do I see this all the time when using the navigation system?

Had this when I first got my 2021. Tried removing and reinstalling card, did not help, did an online search found that if you remove the card and flip to small switch on the side to unlock reinstalled never saw it again. Also never touched it again!

Can you tell me where the sd card slot is. I can find the slot on mu 2019 z21 3500 duamax.

If you have the center console open the top of it. The S.D. card is in the little slot just behind the latching area of the console top. Owners manual has this information in it.

I just bought a 2021 1500 AT4 3 days ago.  I did the “walk-thru” today and noticed this SD card slot.  Do I have to pay for the SD card, or should it already come with the truck, as there was no card installed?

If it came from the factory with Nav, then you should have an SD card. If you are the 1st owner, look in the glove box for it, the dealer may have forgot to insert it. If it did not come from the factory with Nav then I think you are  SOL. GM used to sell them on the Accessories site, but It appears it is no longer available.

Thanks.  Apparently I have navigation but it is accessed via the “Home” screen at the GMC Maps+ app.  
I thought I needed an SD card to access it.

Apparently no SD card needed.

      OCI, not when but why?

      By PunchT37 · Posted

      I agree. That`s a LOT of sludge for 12,000 miles. I tossed that out here since this is an OCI thread. There`s tons of people here that do not post.   I used to work on a city fleet. That includes police cars and fire trucks. Lesson is, not to only use the odo for oci. A police car has a ton of hours on the engine for the miles it shows. And, not just idling, directing traffic. They beat on these things.   Course, since it is a Kia, they were gonna use the "100,000 mile warranty" for their OCI.😉

      Manufactuer's Defect - Paint Failure - Cherry Red High Country 2021 Suburban

      By AlVeron · Posted

      CLASS ACTION SUITS?  Does anyone know if there is already a class action suit for the paint - which was to have been fixed, changed in after the 2020 GM vehicles?  Does it look like this?    Just started 3 weeks ago - No help from GM as of yet - Dealer will not assist in speaking with GM on my behalf. Confirmed it is the paint they use along with the way the put it on that causes it to fail.  Clearly a Manufacturer's Defect.

      That dog don't hunt. 😏   First, a 2025 with 12K on the clock AND idled for a year nonstop is false on it's face; this is 2026. You can do one or the other but not both.    Second, ENGINE HOURS are absolutely available. The rest is third grade math. Micky Mouse scanner he got out of a box of Cracker Jacks OR an ID10T error.    Third, if they ran it out of oil "Several times" that motor is boned on the first hit.    Does this guy think piling higher makes it stink less?

      That's interesting, I assume that would add to the cost of the oil but also I was forgetting to bring up the issue of the low tension rings allowing more oil past which in turn forces the cats to have more oil additives pass through them that wouldn't otherwise so they are creating that problem and of course its all in the name of fuel economy. Mind you the other issue would be the lack of additives that fight the formation of carbon within the piston ring grooves which turn the engine into an oil burner and with in this GM forums case is your average off the shelf Dexos licensed oil, meanwhile the other off the shelf oil being Valvoline's R&P isn't licensed and the only one that is which is that certain Mobil oil that came out recently ( its not even being marketed in Canada ) and only a fraction of vehicle owners are going to be using it out of all the other oils on the shelf or the quickie lube bay that meet the Dexos spec by way of actual licensing.    Also I suspect that its an easy excuse to pool the non turbo DI engines in with the turbo DI engines and design the oil to not have LSPI issues in the most demanding engines and short change the naturally aspirated DI by not offering a higher concentration of additive package they could handle and still not be at risk of LSPI.    I wonder if Amsoil flipped the switch just lately and did whatever packaging designation at the same time as I wonder what oil formulation I would have bought in May, of course I don't know when it was packaged at the factory vs how long it was in storage at the Edmonton warehouse. I know its been said at least in the past that the big players switch over to a reformulated oil but the packaging has not changed until they make that move as well so there is that cross over time where its a new formulation in a predated formula marked package.

      Hmm. A real reason to not just use the odometer to determine OCI?
