Most folks complain about the factory navigation but I love it. Just have to figure a way to keep it updated as the last one was 2016. The looks and screen was little different from a Pacifica we rented two years ago so maybe there's a way. I've yet to locate a mapping/navigation company offer an update other than the folks GM contracted with.
Yup, pre 2012 was able to update with a cheap DVD copy. 2012+ is with a DVD but it is locked to your VIN when you order it.

Thanks for all your advice above. We did buy the 2012 red Yukon Denali from a used car dealer in Conneticut this week, with a little more then 98,000 miles. It was about a 3 hour drive from here, and we went down and looked at it, and decided to buy it, and came back without it to work out the details.The next day my 2003 Yukon SLT had zero oil pressure and bad engine sounds when I started it. So I had to rent a car to go back down there and pick up the "new" vehicle. So now I have to figure out what to do with it.

The 2012 seems in great shape and was GMC dealer serviced since new. But the 97,000 mile recommended maintenance was not done (new plugs, transfer case oil, and transmission oil) of coursde so it looks like that needs to be done. Dash also has a crack behind the instrument panel so it's not that noticeable.I read this is a common problem for the 2012. No problem for the 2003.

The instruction manual is about 1.5" thick and the technology of the electronics is staggering to have to learn and understand.

But even the basics are difficult. GM Recommends ("requires" because of warrranty issues) the GM Dexos oil (or equivalent) which is a synthetic oil. So I looked at the list of approved oils on the GM Website and will have to follow that. I am convinced I got 325,000 miles on my 2003 Ykkon with the 5.3 because of Mobil 1. But in order to try to do that again, it would probably be useful to read these owners manuals and do what they suggest.

The gasoline they recommend is supposed to carry the "top tier" logo, which most of the major brand stations do. There is a list of approved ones on the top tier site. THey also recommend 91 octane, but say you can use 85 and see if it doesn't knock. No MMT.
I presume there is probably a discussion topic about all this on the forum for all these GM vehicles using this DEXOS since 2011, and the gasoline experiience but I have not yet looked. WIth this 6.2 with the FMT, it would appear that for that system to be kept in good shape you need the DEXOS oil and gasoline specs with those additives. But then I guess I can't use the "nameless brand" gas that is a lot less money per gallon.

I stil haven't figured out how to remove the trailer hitch cover , but it has not been above freezing since we got the vehicle. Any one can pass on that information for me? i didn't find it in the book yet.

Seems like it wil be a great ride with a whole lot of improvements since the 2003 SLT, and my wife loves it. Still need to figure out now what to do with the 2003... Fix it and keep it, or unload it for probably next to nothing.

For the hitch cover, there are 2 twist-lock 1/4 turn tabs on the bottom. Turn them and pull the panel down and out. It has tabs across the top that fit into slots in the bumper.

This video is for a 2015+ but it's basically the same....

Thanks for the info on the hitch cover. Had a major problem with my 2003 spare tire mechanism. Apparently no dealer or anyone else ever lubed it, so of course when I needed it once, the salt had totally seized it up. Mechanic finally had to literally cut it away making the system un-useabe. So I carried the spare in the back, but without that third seat, it was no problem. But AAA had to tow the vehicle in because the spare tire could not be lowered.

Anyone else have this issue? I presume the system being totally exposed to the water, wind, snow and salt has a difficult life without some maintenance.

Thanks for the video! If my wife had to try to do that at night to get the spare down, the only way would be that you already knew how to do it. But if it happened she would call AAA and have them do it. Flat tires are uncommon, but in most cases you want to be out of the vehicle and way off the roadway so someone doesn't run into you.

That's great Bob. Yes, it is good practice to inspect and operate the spare tire hoist at least once or twice a year. Mine failed too last year. Mobil 1 oil is Dexos approved. Run top-tier 91 or 93 in your Denali. Exxon is pretty much the best with Mobil a close second. Sunoco isn't bad either. Record your mileage readings and see which works best for you. Around here Shell is terrible but a fella in high altitudes does great with it. Get a Tech-2 so you can work on it. Keep the fluids clean in it and use GM OE or ACDelco Professional parts.

You'll see tons of posts by me and others repeating the part numbers and quantity of fluids for the differentials, trans, transfer case, etc. Same for plugs, wires, air cleaners, etc.
