Delayed Navigation screen loading

After 1 month of owning my new 2019 AT4 without any issues, I had the Nav SD card not installed error. The next day, the nav system went through s long loading process. Since then, with every vehicle startup, I now have a 10-25 second process of the nav system loading before it can be used. Previously, it was always nearly instantaneous. Also, the radio will be randomly self-muted. I brought it to the dealer last week and they did an infotainment system software update claiming to have fixed the problem. Nope, it’s still taking 10-20 seconds to load navigation and the radio was muted this morning. Anyone with 2019 Sierra AT4’s or Denali’s noticing a change in navigation loading, specifically now seeing loading screens where there haven’t been before?  Is this just normal Nav function and somehow, for some reason, I just didn’t have it happen or didn’t notice it the first month? Could GMC pushed an OTA update that now cause the Nav to take longer to load?

I always get the loading screen as well. Seems typical to me and not a major issue. I 

 

Not sure if you noticed it before, but if you restart the truck within some period of time, it doesn’t have to reload the Nav.

 

No idea on the muting part. Never had that issue. There is a setting in the menus that will lower the volume on startup. Perhaps if your volume is too high when you turn it off, the muting is part of the max volume limit taking effect.

I get the same delay as well, since new, never loaded fast, I’ve had it for 9 months /11k.

Thanks for the input. I wouldn’t have thought the navigation loading time was a big deal at all if it had happened from the very beginning. However, I literally had zero nav screen/map loading times, instant on, the first month I drove the vehicle. Then, suddenly, I had the ‘SD card not installed’ errors then nav/map loading screens ever since. The audio issue is also weird. It’s not that the volume was turned down. When it happens, there is literally no way to get any sound at all other than to change from AM to FM or Sat or visa versa. The truck is at the GMC dealership now and they told me today that GMC 2nd tier technicians told them the radio needed replaced. Not sure it will help with the navigation, we’ll see.

I was getting the "No SD card" error about once a week.  It has been two weeks since I locked the SD card and have not had the error code since.

horseshit, especially if you have the navigation feature.

      2015 Sierra Denali L86 cyl 5 misfire at idle

      By Gkistler · Posted

      Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions?

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.

      He is not saying that an SAE *W20 will have more viscosity than a *W40 due to MORE VII polymers. He is saying that although multiple *W40 may post in the PDS the same or similar 100 C and 150 C viscosities that the blenders choice of modifier TYPE and AMOUNT to get his chosen base to grade will not give identical real world viscosities in shear and at temperature. All will pass the SII test but not all will pass the 100 C HTHS (unpublished value) testing the blender does and relies on to get the required by law "percentage improvement' referenced to his last great work.    Tis the problem with the lie. Once told others are required to support it.

      Parking Brake - Automatic Engagement Questions

      By PunchT37 · Posted

      I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.
