Upgrade '16 Denali to HDMI input from '17 models?

Darren S said:

Ok folks . .

The infamously difficult to find a part number for the 2017+ blue USB cable from the HMI to the DVD player / screen / center console is PN# 84275164.

The 2017+ center console wire harness that goes back to the rear seat entertainment receptacle is PN# 84202933. Just a quick note that this required taking the entire center console out and taking it completely apart, which was easily the most intensive work so far. The plus side of this though is that everything is plug and play!

The 2017+ rear seat entertainment receptacle with HDMI is PN# 84144678.

My 2016 Yukon Denali already had the the IO6 version 2.5 HMI and video enabled screen, so I bought a new 2017+ DVD/Blu-Ray player (PN# 84409491) and sent my HMI and the new disc player to White Automotive and Media Services to be programmed.

More to come!

cmatt..
Have you had any revelations? I'm thinking it's a combination of a newer DVD player (84409491) and a newer HMI module (84331776 or 84546904) to make it work.
Did you ever get this figured out ? I'm having the same
I have a slightly different problem. I have a 2018 with RSE (hdmi input). The input is not displaying any res higher than 480p. Signal from a Roku appears zoomed in to just the bottom left portion of what the Roku would normally put out. Yet, other 2018 Tahoes on the dealer lot display 720p just fine. I'm thinking the problem is either my version of the DVD player installed during the build (not support more than 480p from the hdmi input coming to it) or the HMI module. I have 84364936 which is an earlier build than the ones listed above. GM infotainment support is aware of the issue. GM tech support is telling the dealer techs that replacing the HMI won't fix the issue. Of course my response to them is "then what will make it output 720p... if you're so confident it's not in the HMI then where is the problem?". I haven't received that answer yet but will pass along if I find out.

It works!

The key to all of this is the DVD drive . . it is NOT the HMI (although the HMI and the DVD drive need to be programmed, and you've got to be using a 2.5 HMI). I did not connect the grey connector on the back of the DVD drive (because you can't . . they're different sized connectors between 2017+ and below), and am unsure what it's even used for at this point because all audio / video functions work perfectly.

Huge thanks to White Automotive and Media Services for programming / unlocking the 2.5 HMI and the 2017+ DVD drive.

Darren,

I have a 2015.5 Yukon Denali XL. Based on your posts, I believe I will need to purchase the following:

2.5 HMI (part number from the list at WAMS)
2017+ blu-ray player
Blue coax cable (84005111)
Harness for the front floor console (84202933)
Rear entertainment receptacle (84144678)

Can you confirm that's all I need?

You might already have a 2.5 HMI, like I did in my 2016, so I'd confirm first. Either way, you'll have to have the HMI and DVD / BluRay player programmed.

Outside of that, I replaced my center console with a console from a 2017+ escalade that already had the short run of blue usb cabling attached that meets the new blue usb cable I ran at the front (that goes to the DVD, Screen, and HMI), and runs to the hdmi breakout receptacle at the back. All that to say, I'm unsure of what the part number is for the blue cable that's required to run from the dvd / bluray to the receptacle at the back.

Hopefully that's helpful.

Best,

- Darren
