@Ap Hammer Attached is a screenshot from Techline Connect showing the options you need to select to start the process for the USB update.

I can check my laptop later for the specific steps/screens, but it's in SPS2.. one of the options is a USB update, it will prompt you to insert a blank USB memory stick into the computer, and then once it's downloaded you plug the USB stick into the truck and it applies the update.

I was able to resolve this issue, sharing in case it helps someone in the future.. 1) Instrument Cluster (IPC) updates need to be updated via USB after they are flashed. Thanks to William for the tip. 2) Some 2016 Chevrolet and GMC vehicles require an update to be flashed after the Android Auto upgrade (bulletin 16-NA-042) is completed to resolve USB update problems. Bulletin 16-NA-134 addresses this (see attached). 16-NA-134.pdf

Came here to search the exact same issue with my 2016 Silverado 1500! I was having similar symptoms and used my VCX-NANO with SPS2 through Techline Connect to successfully reprogram a few modules last year with no issues at all. I was having ghost chimes, so I hooked it up again this week and saw the Instrument Cluster update available. It said it was successful, however only my gauges work. The DIC stays off, and I have no indicator lights at all except for the normal check engine light at startup.. no turn signal indicators, headlight indicators, etc. Cruise control are the only steering wheel buttons that work. I reflashed the calibration a few more times hoping it was a flashing issue, but nothing changes. I am guessing that the latest Instrument Cluster calibration should not be flashed on all vehicles despite it appearing in Techline. I am aware that every TSB I have ever seen warns not to flash calibrations that aren't explicitly called for, but it's too late to undo that now. I'm going to try checking with local dealers, but is there a way I can flash the previous calibration version myself?

I came on here to research this exact same issue. My factory bulbs had a dab of paint on them, which shielded the camera from the glare. Been trying to find an economical solution for awhile myself.

Also considering these on my 2016 Silverado 1500.. did either of you end up purchasing these?

I wanted to provide a follow-up post for everyone regarding my attempt at upgrading my the rearview mirror in my Silverado 1500 LT with the custom harness from @pgamboa and the Gentex mirror from @rjp869 -- it works great!! I now have Homelink buttons built into the mirror, and auto-dimming on all my mirrors (I had previously upgraded my side view mirrors with Phil's DL3 custom mirror upgrade). Phil and Bob are both true professionals that we are fortunate to have in this community. Both of my transactions with Phil were very easy, with incredibly fast shipping and great post-purchase support when I didn't understand something. Bob was equally fantastic, with fast shipping and great service. When I tried this installation, it didn't work at first -- I assumed I had messed up some wires, but Bob thought it might be his custom connector on the mirror. I sent it back to him and he rebuilt the connector and shipped it back to me on the same day he received it! He even offered to reimburse the return shipping for me. If anyone is considering this mirror upgrade, use Phil and Bob and you'll be in good hands! -Mike

Thanks Phil! I reached out to the seller and he replied back looking for more details about your harness, so I directed him to this thread and explained what my ultimate goal was. He did confirm that the presence of OnStar in my current setup and the lack of it on his mirror will not cause any problems. Will post an update for everyone's benefit if I hear anything. -Mike

I have a 2016 Silverado 1500 LT with the DL3 side mirror upgrade using pgamboa's harness. My existing inside mirror is the non-autodim OnStar model. I'd like to get autodim plus Homelink on the mirror.. I don't need OnStar. The Gentex GENK40A4 appears to do this.. but would it work in my scenario? And would the side mirror dim? There's an eBay listing right now that says it's plug-and-play "as long as your vehicle currently has the factory 10 pin auto dim mirror without OnStar." That's not what I have, but curious if pgamboa's second custom harness would get me what I'm hoping for..? -Mike

Just wanted to share a positive vote of confidence about my experience upgrading from DL8s to DL3s with pgamboa's help.. his harnesses make the process very straightforward, but his tech support is what puts it over the top! Just follow his guidance and you should be fine. A few small tidbits I would like to share with those looking to embark on this adventure: 1) It is very doable, even if you are not a "car guy" or electrical genius. It takes some time, but it's not complicated. 2) Sheet metal is sharp, especially in areas that GM didn't expect customers to be sticking their hands. 3) Remove your door speaker! It's simple but took me awhile to realize how much easier that made things. It's only one screw and a simple wire harness. Thanks Phil!

Here's another positive review for pgamboa and his custom harnesses!! I have a 2016 Silverado 1500 LT crew cab and upgraded from the standard DL8 mirrors to the DL3 like most of you. When I first started researching the upgrade and discovered all of the wiring differences, I almost wrote it off and decided it wasn't happening. Thankfully I happened to come across one of Phil's posts about offering his custom harnesses for sale, so after grabbing a set of mirrors from another member and a new door switch, I dove in head first. Not only did Phil ship quickly (literally within an hour of my payment), but he also virtually held my hand as I worked my way through the install. I had a few questions along the way, and he replied to my PMs within minutes. It was mostly silly little things, but he saved me lots of time and headache by pointing me in the right direction. The price is more than fair, as these harnesses are complex and he clearly knows what he is doing -- not to mention the tech support he provides. I am very happy and could not have done my upgrade without Phil's products or his knowledge. Thank you sir!
