Has anyone tried this yet?

 

 

I set up an appointment Friday to have the firmware in my stereo updated and will be ordering the 2.5 HMI module tonight to see if this actually works.

For anyone interested I believe I will have the ability to do programming very soon. I have made quite a bit of progress and hope to have the reprogramming method refined and ready within the next few

Making even more progress! HMI has been updated to the newest software, which means Wifi compatibility ! OTA updates are enabled, meaning you will receive all future software updates for the HMI over

For anyone following along I am once again waiting for parts. I was having issues with the radio module I had originally ordered. A new module is on order and should be installed and ready to go by th

I did this, since my 2016 was one of the trucks that had the $200 rebate for having the old 2.0 hmi and no apple carplay or android auto.

However I went through these guys, https://www.gm-navigation.com

It's a little pricey, but the hmi is already programmed with your Vin and whatever options you want. And mine works great, the only glitchy thing I've ever encountered is the pandora app on my home screen can be finicky, but pandora plays fine through android auto so whagevs.

From what I am seeing it's a little more friendly to iPhones just swapping out the HMI.  I'm taking a chance, will just upgrade what I have to to get it to work.

Mine was less than that. But yeah, I paid extra for a no hassle plug and play. I suck with electronics, so I was willing to pay extra for it to be easy.

Yeah, if I'm going to drop that much money I'm going to gut it and replace it with aftermarket.  Those guys look like they offer a good service and I know a lot of people here are happy with them but I don't want factory Nav and I won't pay a premium for it.  I just want Carplay added.

Module arrives Wednesday.  Had the truck in the shop on Friday and got the radio software updated to try and alleviate any potential issues there. 

If I can get the module in Wednesday night I'll definitely update, good or bad. 

Only roadblocks I see right now is I have the old USB ports in my console (with the SD card slot), some guys have had to upgrade to the new USB ports.  That said, the guys that have had issues with the old ports were on android which apparently requires more bandwidth than Carplay.  I'm on iOS so I'm hoping for the best.

I hope it works as I want to add CarPlay to my 15 especially with iOS 12 adding Waze and Google Maps. I seen some listings on eBay that offer the 2.5 module without GPS and USB ports already programmed to your VIN for like $600. If it can be had for cheaper that will be great

The third party Nav apps coming to iOS is what finally lit the fire under me. 

 

Also, don’t pay $600 for just the HMI module. Look in the comments of the YouTube video. There’s a guy listed there selling them for far cheaper than that.

Alright, Ladies and Gentlemen. 2.5 HMI module arrived today and I swapped it out. It takes longer to get the glove boxes out than it does to swap the module. 

 

The bad news, everything except Apple CarPlay works. It just doesn’t detect the phone. That said, I have not yet upgraded the USB connector in the armrest. That will now be my next purchase to see if that makes it work. 

 

If if that doesn’t, the next thing is apparently the radio module and I have been told that is relatively reasonable in price too.

I think it will work with the USB connector based on the comments on the YouTube video. It seems that the people having problems are with Android. I’m going to order the HMI and USB connector

Keep in mind, my truck is a 2014, non-Bose, non-Nav. The people that this has worked for on iOS, from what I’ve seen, are in 2015’s. I’m prepared to ultimately spend whatever I have to to make this work, I’m just trying to logically get to that point as cheap as I can.

      2018 Silverado Console USB Port Not Working

      By Tbhats2130 · Posted

      My centre console USB ports haven’t been working and the one in the glovebox is starting to act up. When I plug my phone into the cord the radio will go black and stop playing, and the CarPlay is inconsistent.   I checked the fuses and they were fine. I changed the USB port out and still nothing. Hoping for some advice on what I should be looking at.

      The truck is a 1995 Chevrolet S10 Blazer, 4.3 VIN "W" engine. :cracks knuckles:   On a whim - because I needed a headache - this truck was for sale so I stopped to take a look. Doesn't run. Well, it does, but barely. Long crank, choppy idle, bad misfire(s), it REEKS of fuel. I can DO this..I'm thinking. Diamond in the rough. One owner until last year. A young guy is selling it, he bought it 6 months ago. It stranded him more than once, he's got a newborn. It was in the shop 10 days ago and he "thinks" they said it needs a new fuel injection system. He can't put any more money into it, needs it gone. I was thinking of upgrading my Macbook, which is a total want, not a need. For less than the price of a new laptop I can have fun for months tinkering on this truck and enjoying it. I'm taking this truck home. The guy was beyond thrilled, his wife was there, she thanked me profusely, I could tell they were hurting. They seemed like good people in a bind.   Some parts, a wash, maybe a set of tires, and I can have a few months of fun and then turn it for beer money (or the next project).   Sure enough, there's a work order from a shop last week in the INCHES of paperwork on this truck dating back to when the first owner bought it. They put a new distributor in it, fuel injection work describes basically opening the plenum and putting it back together. He said he couldn't afford any more work so he had them button it up and that's when he put it up for sale.   I'm not well versed in 4.3. I did discover 1995 uses the 1992-1995 SCPI "Spider" injector which is riddled with issues from splitting lines, clogged or cracked poppet valves and plastic spider legs that crumble over time. Cool. I'll just order me a ne---. Oh, the auto parts store doesn't have it? Rock Auto doesn't have it. eBay? $$$$$$ for used. These are UNAVAILABLE period end of story unless you know "a guy" who's still got one in a box somewhere.   Can't upgrade to the '96-'04 injector, it's a different plenum, wiring/pinout and sensor config.   There are a few kinda "know a guy" -guy rebuild services for these injectors out there for about $350. Okay, Okay... I'd like to know if anyone has used them? Anyone got a lead on these crappy 92-95 spiders?   I also don't want to send MY spider to Narnia and back without knowing if that's truly the problem. I guess I'll need to pull apart the plenum and do some digging.   I was also thrown for a loop. This 1995 model year truck has an OBD-II connector. The interface is decidedly not OBD-II. I can read and reset trouble codes and view live data, but there's not a lot of data. Like misfire count and on what cylinder, that's not there. It's OBD-1.5.   Nothing is ever easy. Now it makes sense why this guy wanted to disappear this thing for cheap. I'm guessing the shop told him the injector is toast, the part is unobtainable and they're not going to sort sending the thing to a rando offering rebuild service on craigslist, and the kid likely can't be without a working car for 3 weeks even if they'd facilitate that.   Experience with these early SCPI's? Stories? Things to check? Sympathy? (..Nah...)   This can sit until I sort it. But I haven't had a problem with a vehicle I couldn't easily solve in a long time.

      I have four that read by the dash 8 to 10% better than miles/pump calculations and I have one that is spot on.
