So my 2014 Denali is in for some work (leaking front diff, seat heaters not working) and they gave me a new 2015 Sierra as a loaner for the week. I've noticed a couple of new features and was wondering if anybody knew why they couldn't be added to the 2014s. They seem like simple SW updates. I'm asking about the 4x4 menu in the Instrument Cluster (N/A for 2014), the sound settings for the radio (2014 only has talk and manual - 2015 has 6-8 sound settings), and the text messaging feature (N/A on 2014). Are there HW differences for these features?

Thanks.

I thought I read with the 4x4 screen it's not a simple software update. The truck needs an entirely new body control module as well.

Christ white can add that 4x4 screen to 14's I have read, not from GM directly. Text messaging can also be added by him.

 

The 2015 uses capacitive touchscreen (ones found on modern day smartphones) 2014 uses resistive (pressure points) and this limits the 2014 to single point touch, 2015 can handle pinch zoom on the maps etc.

 

But 2014 should work with thick gloves while 2015 will require fingers exposed.

I was wondering why the '15's screen seemed more responsive than my '14. Now I know why. Thanks

what 6-8 sound settings are you speaking of?

i just got my 2015 Denali and it looks the same as my 2014 (i did upgrade the HMI module in the 2014)

all i have is an icon for talk and the EQ icon. (i haven't used either) i just adjust the bass, mid and treble.

 

i will say for the record that i am convinced the sound is better in the denali than the All terrain i had previously. both were Bose but this Denali is supposed to have 7 speakers (sub under center console)

while i could not prove or disprove my 2014 had the sub, they both have excellent deep bass. in fact i think the denali has a little more, but more significant the denali seemed to have a lot better stereo separation.

I've been a car audio guy for about 30 years now. trust me i have installed some of the most amazing audio systems and frankly for a factory stereo the Bose is damn good as long as you listen to actual music and not rap crap.

i find it more than adequate, better than many aftermarket solutions.

but the denali system seems just a bit better.

and trust me, that is a pretty big compliment from someone like me..

Chris can add the 4x4 screen, other than that nothing is cross compatible or swappable between the 2014/2015/2016 years as far as the infotainment system goes.

      I like the idea.  I would pick diesel if I had a choice. I need pictures though.

      Help purchasing a touch screen digitizer

      By newdude · Posted

      I've installed cheap eBay new aftermarket digitizers before.  They work.  Did a bunch of Cadillac CUE (aka Cadillac's MyLink) for someone years ago.  They all worked fine after the repair.    That number 22740886, that is a component part # for GM.  You can use it to search, but its not something that's obtainable at the dealer level.     So pretty much any of these will work - 2015 Colorado Digitizer for sale | eBay

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
