I have found several options to upgrade the OEM (non Bose) system to add Nav....Has anyone had success in this?  Found the control unit and SD cards from different vendors....just don't want to invest if this is a headache waiting to happen!

Might be easier for u to just replace with aftermarket. Be cheaper. I have a bose system and installed a pioneer headunit. Gave me android auto, screen mirror, nav and rear.seat entertainment. Got the radio for 500. Needed a few other bits. All in all 900

For starters, can't do it from GM, they discontinued the SD card upgrade. 

 

You MUST verify what radio you have first.  If you have the IOR 8 inch radio, there is no nav upgrade.  You MUST have IOS radio to do it.  IOS is standard on an LTZ, and optional on LT and RST.  Its part of the Convenience II package.  Easiest identifier is the vehicle build sheet or, if you have the power sliding rear window on an LT or RST.  If you have the window, you should have IOS radio.    

 

This place would be your best bet:  https://www.gm-navigation.com/shop/2019-chevy-silverado-factory-navigation-system/

 

These guys are good too:  https://www.infotainment.com/products/2019-2020-chevrolet-silverado-mylink-iou-gps-navigation-hd-radio-upgrade

 

These two options involve no aftermarket splicing/swapping/headaches.

Wonder why GM dropped the SD card upgrade? I did it three months ago and it works very well.

This seemed to be the easiest but doesn't show on their website anymore. It was there probably 2 weeks ago. Emailed them and they said only doing 2020 Silverados right now, were having problems with other years. $599 if you have SD card reader in center console, $699 if you need new usb / card reader hub.

I've noticed at minute 4:48 that "OnStar Connected Navigation" is showing.  Is this to be used only with OnStar?

I am wanting to do this also, I believe the sd card could be purchased on eBay but not sure If it’s plug and play. Anyone done this themselves?

Inquired about upgrading to navigation when i purchased my truck. Dealership said that was not possible. I'll show them (hopefully).

I don't believe so. There is an option to get directions from an Onstar advisor but since this mentions the SD map card needs to be inserted in the SD slot in the center console I believe that is where the map info comes from. I still haven't decided which way to go. I tried an address the other day in my 2017 Silverado and the business had since moved so new location wasn't found, my phone showed new address. Android auto and Apple Carplay will always have latest map info since it comes from your phone.

I have some good news and bad news about the GM nav upgrade for ios radios.

The good news: I found a dealership with 3 of the cards in stock. GM Part Number 84489271. They originally bought them for a commercial client with 3 WT trucks, but found out they wouldn't work due to the trucks having ior radios.

The bad news: I asked this dealer to investigate whether this could be installed on my truck. They called GM. GM has abandoned the program for the dealership techs to do the reprogramming upgrade after the cards are installed. Upgrading is not possible through GM. Only viable solution now is to go aftermarket.

      Missing thrust bearing? And oil selection

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.

      Missing thrust bearing? And oil selection

      I agree with this assessment. As you know I’m testing longevity with vehicles for the first time. I have a few vehicles I passed to kids and grandkids. We’re all past 100K miles some approaching 170K. I’m the only one doing 5k oil changes. The rest whatever the minder says. I’m the only one doing frequent transmission service. My odyssey the trip vehicle at 200K will be finished as a trip vehicle. I recently changed to high mileage oil, Valvoline. I can’t get past the fact that all manufacturers want to claim long service life. I just don’t make sense that they would go with low weight oil for mileage. While sacrificing longevity.

      There's absolutely a mountain of profit in catering to the "I do my own research" crowd, people who are certain they know better. And I don't mean there isn't data to support that 0w40 produces less wear product than 0w20 in an engine like the 3.0 Duramax, that only feeds them the assurance they need. Again, my whole thing with oil selection is, sure, 0w40 or 0w30 produces less wear product. Are we talking the difference between the engine lasting only 100k versus 200k? Or are we talking more like, if the engine will already go 350k on a good 0w20 regimen recommended by the OE, is using 0w40 going to get us to 355k, assuming we can even get the rest of the truck to last that long, meanwhile sacrificing the first 5y, 100k in powertrain warranty. The answer isn't easy, there are tradeoffs.   I willfully use 0w20 Dexos D for this reason, knowing that a 0w40 will produce slightly less wear. I don't believe the delta in wear product is meaningful over the lifetime of the engine, and I place much more importance on driving style and overall feeding and care of the engine as a whole. It's the mentality that someone can abstain from alcohol their whole life which is an amazing boost to health by itself, theoretically. But if they're sedentary, that lifestyle choice will most likely kill them young despite their other, concerted efforts. Maybe someone doesn't drink AND they are the perfect picture of health and activity AND they use 0w40 AND they treat their engine perfectly. If living until 130 years is the goal, sure, do that. But it's going to be a really old truck falling apart around a good engine for that last 30 years, without a doubt.   I watched Demonworks' other video on the 100k+ 3.0 Duramax that had dealer 0w20 changes on what appears to be OLM-prescribed intervals (8-10k).   The QR codes are still present and readable on the main bearings. That's how little wear it has.   That's not proof that anyone else should stick to 0w20, but it's confirmation, for me, that 0w20 is perfectly acceptable to use in these engines.

      Castrol Edge VS Amsoil OE

      1Based on independent testing of OE 0W-20 in the Peugeot TU3M Wear Test as required by the dexos1 Gen 2 specification.
