Profit? That never happens, but that would be awesome! Thanks!

Well here's one selling for $700

 

And here's the lowest price one I could find at $375

 

Even sold at $300 you're still profiting almost $150, as you'd only need the HMI and the USB.

 

Also, side note, if someone wanted to do the carplay/android auto mod and retain an I06, here's a 2.5 HMI selling for $350 (great price for factory nav and AA/ACP capability)

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

Well then I guess the beers are on me if I can sell it! Will I need to go to the dealer to get it updated or is that already done on the hmi module? I think I have the "2015.5" version as I have a text app on my display now

I believe the logic there is install it first and do the update at the dealer later if you need to.

So is it safe to say the following is true:

2014-need to upgrade radio module 

2015-need to upgrade radio firmware 

2016-nothing additional needed

 

I included 2016 since there was a shortage of the 2.5 HMI for a bit for that years model

I believe all is true except, 2015 might need radio module, 2015.5 may need firmware

Looks like my 2.5 hmi from dokus223 on eBay will arrive tomorrow. It’ll go into my “shortage model 2016”. I’ll report back as soon as I install. This is a great thread!

OK, update time. 

 

First of all, don't get your hopes up for self programming.

 

I don't know if it's that the VCX Nano is a piece of shit or that I legitimately cannot program a newer module in an older truck but that seems to be what's happening here. 

 

Module stays blank, cluster display states "audio off", no chimes or any audio are heard. 

 

When I attempt to program, the programming fails. SPS cannot even see the SW version currently installed in the radio module.

 

Looking further into this, it appears I may need a harness that has an ECU and a BCM from a newer vehicle in order to complete the process.

 

If I had a 2016+ vehicle to use as a test I would, but unfortunately I don't have access to one.

Well I guess the other big take away is that it absolutely must be programmed. At this point how sure are we that the dealer can do this on an older truck?

Oh yea she needs to be programmed. 

 

As of right now, I don't know if this is something even the dealership can do. It is against GM policy to swap a used part into a vehicle and it might not even be possible for them to swap.

 

As of right now, it looks like sending it to our boy Dokus might be the only option.

I just sent a message to Dokus to see if a VIN programmed receiver module would work and how much.  If he replies in the affirmative I'll take the hit and order one.

Also, @th3magpi3, what was involved in replacing the receiver module?  Is it behind the glovebox too or behind the dash panel surrounding the display panel?

Pry tool, 4 7mm bolts, various clips. Behind panel. 

 

It's the top module

Gotcha.  What's the module below it?  Don't remember seeing another one on any of the diagrams?

      seat base height *lowering* (base 40/20/40 seat, 2026 1500 WT std cab)

      By bwiese · Posted

      Folks, Have a great new 2026 WT  (std cab, 2.7/4WD) w/base 40/20/40 mech adj bench "fake buckets"  (with lower and upper center console) heavy vinyl seats.  Overall the seats are very comfortable and the vinyl is heavy and appears less likely to 'split out'. Am very tall (6'5")  + a bad back/osteporosis/former hyperparathyroidism so ease/range of movement is a bit restricted.  The truck rides a bit high and I use a nerf step bar w/my left foot to step in, then I put right foot/leg in, drag my butt in  & get seated.  Worked fine in my 2018 RAM quadCab. But I end up dragging my butt over the left raised sidecushsion area of vinyl seat, and due to texture there's fair amount of traction on slide inward.  (ArmorAll didn't improve.) If the seat were even ~1/2" - 3/4" lower it'd be helpful, but base seats just have the forward/backward underseat bail and the side lever for tilt which really doesn't affect seat height.   I really don't want to 'de-puff' the left side sidecushion forming the  fake 'bucket'. I know one company sells 'seat elevator blocks':  but is there a simple way of lowering the height of the driver seat instead?   Thanks Bill W San Jose

      I have a basic 2026 1500 WT  (2.7L/4WD reg cab shorttbed). Comfy, generally happy with electronics/radio - but is there a way I can add switches to steering wheel right-side position (curr. empty) so I can adjust volume, push phone button to voice dial, etc? Bill W San Jose

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By Tyler Gibbs · Posted

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Dave's Auto (custom engine builder) tear down of L8T

      By No F-bdy Bs · Posted

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.
