Interchange 8in for 14in display?

Did you buy the truck used? Previous owner probably did the swap themselves. I have not heard of someone making a harness sorry.

 

No, bought new (it's a '24). Completely OEM.

 

Electronic seat adjustments?

 

I am sorry... you bought a stock OEM Tundra (TRD Pro trim) and you have NO volume knob with the (stock) 14" screen? Can you upload the pic? Am I the first one to be surprised to hear that?

 

He said TRD OR so assuming he just means package, not the Pro trim. I’d have to see pics as I’m wondering if he actually has the 8in screen and is not knowing exactly what that’s measuring since it’s highly unlikely he got a 14in screen and no volume knob from the factory

 

That's exactly why I found his question very confusing.

 

@johnson156 yes, both driver and passenger electric front seats.

 

@Pine_Cone67 not a TRD PRO, A TRD Off Road (OR) and yes, it is most definitely a 14" screen with no volume knob. I have pulled the HVAC panel as well and there is no wiring for a volume knob hiding behind it as others have found. I'm not sure why that is so surprising to some (@Goobax) as there are way too many factory inconsistencies throughout the 3rd gen Tundra, which can be realized by reading the 3rd gen section of this forum. I can absolutely attach a picture later tonight when I get home to show if people are really that skeptical.

 

Please do show us what you have because - if true - it will be an absolute unicorn. Below is things should be, at least based on what Toyota is printing in the manual (B is the volume knob):

 

Yep my bet is it’s used

 

Definitely a 14" screen without a volume knob... and it doesn't really surprise me though. A quick search on those switching from the 8" screen to the 14" screen shows weird shit as well. I am not the only one that does not have the wiring connector. Lhh305 and TigWeldingCreations both mentioned they did have it either. KroppDuster was trying to come up with the commonalities, but kept getting conflicting info (not sure where he is at with it at this point). And just so we can clear it up again, I am the first owner of this Tundra. It is a 2024 and I bought it over Memorial Day weekend this past May. I have NOT changed/added anything yet in regards to the audio system.

 

@terraj66 you're betting what's used? The truck? Cause I already clarified to you that I bought it new. It is a 2024 that I bought over Memorial Day weekend this past May. Are you referring to the screen being used? Cause if that is the case then I am smart enough to have clarified that in first place. I have not changed/added anything yet in regards to the audio system.

 

@H2ODoggy78 Do you have the window sticker from when you bought this new? Are you sure you have a TRD OR package truck? You are missing the red TRD start button. I believe the SR5 also needs one of the TRD OR "Premium" packages w/options or Advance technology packages to get the 14 screen from the factory. Window sticker might help clarify if it's in fact something messed up on the build.

 

New to you, or new off showroom floor with just test drive miles?

First time that truck been titled?

Your missing the locker switch as well

Doesn't look like a trd off road but who knows if this new or used

 

Exactly why Toyota wouldn't sell them this way. If they did, they'd have incorporated digital controls on the UI. And it likely wouldn't be an option to have a external volume knob. Either they all do or don't. All Tundras with a 14" display do, or in your case, should.

 

we have a 2024 Tundra on our showroom floor with the 14" screen, the JBL system has the large knob, just below and to the lower left of screen. His screenshot shows it as a NON JBL system, maybe ?

 

@Fxclm5 really man? I kinda feel insulted that you would ask "new to me" when I have stated multiple times now that I bought this truck brand new off the showroom floor, or more exactly off the dealership "New Vehicles" lot. As stated, it is a 2024 that I bought on Memorial Day this past May. Other than the 3.5" RC Vertex lift and 35X12.50X20 Nitto Ridge Grapplers, I have not done any other upgrades/modifications yet.

 

@Toyota_Ed yes, it is a non-JBL audio system.

 

Based on the pic you posted earlier, it appears you got an incorrectly built spec truck as it has been established that all 14 inch system (with or without JBL) should come with a volume know (as documented in the manual I found and posted above). Depending on how important this feature is to you, I wonder whether you have any recourse in taking the truck back to the dealer and requesting a proper fix - installation of the climate control panel with the knob (plus whatever else needs to be done). Crazy but I guess stuff like this can happen on an assembly line.

 

@H2ODoggy78 Just curious what your window sticker shows from when you bought the truck? If it lists the 14" multimedia screen as an option, then you should most definitely have the volume knob. It doesn't come without it unless something else happened with the truck between the factory and the dealer.

 

@SpilledTheSalt that is a great suggestion. I will have to find the window sticker. Unfortunately, for the life of me I cannot remember where in the hell I put it. I do remember it stating a couple of packages that are apart of the build. I know for sure one is the SR5 Premium Package and I believe the technology package (i.e. BSM, RCTA, automatic braking, etc.). I assumed it also had the TRD OR package (yes, I know, the window sticker will state such, but I honestly cannot remember if it was on there or not) since it has the rear decal stickers, the TRD "honeycomb" grill, and 20" matte-black TRD wheels. As you, and others, have pointed out missing details that TRD OR equipped Tundras should have, I am really questioning if the dealership just added the rear decal stickers. I am making it my weekend goal to search and find my window sticker and hopefully find some answers.

What started all of this was my questions regarding the volume knob, or lack of, and looking for info from the forum. Yes, I bought my truck brand new and yes, it came with the 14" infotainment screen. However, it did NOT have the volume knob (only the volume controls on the steering wheel) and sucks for me, but it also does NOT have the wiring connector behind the HVAC panel as so many others have found with their Tundras. Something that doesn't make sense to me is those that have switched from the 8" screen to the 14" screen and have the wiring connector hidden behind the HVAC panel plugged into the dummy connection point. The 8" screen has the volume knob built into the head unit itself vs the 14" with a separate module and wiring for the volume knob so common sense would say there is no need for wiring connector. Now, if Toyota simply makes one harness that they install at the factory for all models of Tundras and then of course equipment gets installed according to the package(s), then by all means I would understand why those that came with an 8" screen from the factory would have that wiring connector hidden back there. That being said, then my truck should have the wiring connector no matter what (8" screen vs 14" screen; volume knob or not), but there is not wiring connector that I can see.

Hopefully I do not convolute matters by saying this, but if I had read anywhere from anyone that swapped from an 8" screen to 14" screen that they did NOT have the volume knob wiring connector it would help clarify that Toyota factory does indeed have different harnesses (in regards to the head unit ONLY) for the 8" and 14" screens in 3rd gen Tundras. If they did production in a manner that "just makes sense," then in regards to the head unit ONLY, all models of Tundras get the exact same harnesses installed at the factory, and then of course it is simply the packages that determine the equipment that gets installed. If the equipment doesn't have the function, then the plug gets installed into a dummy port, which is what I have seen in 99.9% of 3rd gen Tundras in reference to the volume knob, of course. If by chance I am not in that unlucky .1%, then I need to remove my head unit and the HVAC panel, and hopefully by the Grace of God, the wiring connector came loose and is dangling somewhere in the rats nest of wiring harnesses behind Qi wireless phone charging panel. I am due for some good luck....

p.s. my apologies for such a long post.

 

@Pine_Cone67 unfortunately (and the way my luck usually runs) I most likely got a truck with a screw-up from the factory. But what intrigues me the most, is that all of the people I have spoke to and/or read their posts that have done the 8" to 14" upgrade, all found the volume knob wiring connector plugged into the dummy port on the back of the HVAC panel in their 3rd gen Tundras. With that being said, it makes me think that from the factory all models of 3rd gen Tundras get the exact same harness (in regards to the head unit only). Then the equipment gets installed according to the package build sheet. If the equipment doesn't have the function (in this case 8" screen with volume knob built into the head unit) the connector(s) gets stowed, and this is what I have seen so many times with those completing the upgrade from 8" screen to 14" screen (JBL and non-JBL audio systems). As I had just wrote in my reply to @SpilledTheSalt, I am hoping that I am NOT in that unlucky .1% and the connector just came loose and is dangling amongst the rats nest of a wiring harness that is below the head unit. I am going to pull out the head unit and HVAC panel and do a thorough search through the entire area in the dash and pray that I find the connector laying loose somewhere.

 

the inner dash wiring harness part# states the harness's are different, depending IF they have the JBL system:
"82141-0CF90" JBL w/12 speaker system USA specs

 

Why wouldn't you just take it back to the dealer and show them the issue? It should have a volume knob if the 14" unit was installed at the factory. Toyota should fix it. It was a new truck when you bought it and I assume still under warranty. They can pull up the build information to confirm the options that were Factory installed. No need to find the window sticker.

 

Your missing the locker switch, that is the most important thing in the trd off road package.

That's why it really seems awkward your truck is built wrong, not just your 14" volume knob.

 

Does the dash VIN match the window sticker?

 

Not my truck, that op decided to tear into the unit looking for a loose harness.

Still curious if he got his locker switch addressed or not

 

Most likely it's trd sport, not trd off-road. Anyways this is the weirdest spec I've seen

 

@Fxclm5 So yeah, I have come to find out quite a few disappointing facts. Let me start by saying, yes, I was led to believe I was buying a TRD OR equipped 2024 Tundra. I will admit I was not fully versed in what makes it a TRD OR at the time (this is the first foreign manufactured vehicle I have ever owned, and yes I do know it was built here in Texas. I have always owned Chevy trucks prior to this Tundra), and this is completely my fault for not doing due diligence to know all the details. Shame on me.
All that being said, my Tundra has the TRD OR stickers on both sides of the rear truck bed and has the TRD wheels, all original as I first saw it on the dealership lot. Again, me not aware of what a true TRD OR equipped Tundra should have from the factory; I believed I was buying one. In all honesty, I never even looked into all of this until trying to figure out the whole volume knob issue.
I have recently looked up my VIN through the Toyota website to see the actual build, and as I am sure you already know, I do NOT have a TRD OR equipped Tundra. I have an SR5. Here's where things get extremely confusing to me. It shows that at the "Port" the 20" TRD wheels and different tires were installed. It states that I have an 8" multimedia screen (there are other options that are listed as well, but I cannot get the website to pull up the vehicle's specs off the VIN right now). I definitely have the 14" screen as seen in the pictures I previously posted. So all I can figure is the dealership swapped out the screens, or the Toyota website for my VIN specs is wrong, and the dealership also put the TRD OR stickers on the rear of the bed (No, I did not put them on). If the dealership swapped the screen to the larger one, then they coded it to the VIN because I have had Toyota Connected services since the day I bought it. If the dealership had nothing to do with the head unit and the website is incorrect for vehicle specs per the VIN (8" screen vs 14" screen) then I got the tarded unicorn that did not come with the volume knob from the factory as well as does not have the plug and harness to connect a volume knob and module.
I have called my salesman and am waiting a return call from him. Hopefully he can shed some light, but I'm not getting my hopes up.

 

Tbh, i would ask dealer wtf happened, they led you to believe it was a trd off-road, since it had the rims and the stickers, was your front grill swapped as well to a trd or still sr5 style?
