Ask any 70 Series owner what they love about the 70 Series and you will hear about the engine, the suspension, the resale, the indestructibility. Ask them what drives them mad after a big touring week and the conversation shifts quickly: wind noise, a wheel that does nothing, a head unit from the previous decade, and a gear knob positioned as though ergonomics was a foreign concept. Almost every technical write-up on the 70 Series covers DPF issues, clutch wear and chassis concerns. Almost none of them cover the thing owners live with every single day, which is the interior.
This article covers only the cab. What Toyota left alone, what eventually changed and when, and what you can realistically do about each complaint. Where there is no good fix, that is what you will read here.
At a Glance
- The 70 Series interior has changed very little since the current body style arrived. Most of the meaningful updates only came with the 2023 facelift.
- Factory cruise control arrived in 2017. Any 70 Series built before that has none at all, and an aftermarket kit is the only solution.
- Factory steering wheel controls did not arrive until the 2023 facelift. Every pre-facelift 70 Series has a plain wheel with no buttons and a clock spring with no provision for them.
- Noise, seat comfort and the hard plastic dash are genuine long-haul complaints with limited factory solutions.
- Several of the cabin frustrations have practical aftermarket answers. A few do not, and it is worth knowing which is which before you spend money.
Three Eras of the 70 Series Cabin
The easiest way to understand the interior history of the 70 Series is to think in three distinct periods.
Pre-2017: No factory cruise control. No steering wheel controls. The wheel is a plain four-spoke design that has barely changed across decades of production. The factory head unit is a basic analogue system with no steering wheel integration because there is nothing on the wheel to integrate. If you own one of these, every convenience feature you want has to be added from scratch.
2017 to 2023: Toyota introduced factory cruise control with the DPF model update. That is a genuine quality-of-life improvement for highway driving. Steering wheel controls, however, remained absent. The wheel stayed the same, the clock spring remained a single-function unit for the horn and airbag, and head unit integration with the wheel was still not possible from the factory.
2023 facelift onwards: This is where Toyota finally addressed both. The facelift brought steering wheel controls for the first time in the model's history, meaning the new wheel has buttons and the factory clock spring now has the contacts to carry audio, cruise and phone signals through it. On a 2023 and later build, none of this requires any additional hardware. The wheel plugs straight into the clock spring and everything works as you would expect from a modern vehicle.
If you own a pre-facelift 70 Series, understanding which era you are in matters a lot when you are deciding what to upgrade.
The Steering Wheel
The factory 70 Series wheel is a large, plain, four-spoke rim that has not meaningfully evolved in decades. It is not offensive, but it is not comfortable for long drives, it offers no hand purchase around corners, and before 2023 it has nothing on it at all. No audio buttons, no cruise resume, no phone answer. You reach for a button that is not there, every single trip.
On a pre-facelift model, the reason you cannot simply wire up a replacement wheel with buttons is straightforward: the factory clock spring has no provision for steering wheel controls. The clock spring is an essential part of the SRS airbag system and you do not touch it. The clean solution is a wheel upgrade that keeps the factory clock spring exactly where it is and bridges the new wheel's button signals to the head unit wirelessly via a steering wheel controls module instead, using the horn power circuit. No custom loom, nothing permanent. The 70 Series Steering Wheel Upgrade Kit does exactly that for pre-facelift vehicles, using a 300 Series style flat-bottom wheel design. On a 2023 facelift, the wheel swaps directly and the buttons work through the existing clock spring with no module required.
No Cruise Control on Pre-2017 Builds
If your 70 Series was built before 2017, it left the factory with no cruise control whatsoever. This is not a setting buried in a menu. It simply does not exist. On a long highway run or a stretch of outback bitumen where the speed limit is consistent for hundreds of kilometres, the absence is exhausting in a way that mechanical issues rarely are.
An aftermarket cruise control kit is the practical answer here and it is one of the more worthwhile things you can do to a pre-2017 70 Series. These kits are model-specific and pre-programmed for the 70 Series, which avoids the calibration headaches that come with generic units.
The Head Unit and Screen
The factory head unit in the 70 Series is a basic analogue setup, and so is the wheel. The button signals, where they exist at all, are a simple resistive signal rather than anything running on a data network, which is why adding controls is a wiring question and not a software one. The factory screen is small, the resolution is dated by any current standard, and on a facelift running the factory unit you are still not getting navigation, streaming or split-screen functionality.
An Android Automotive OS head unit makes the biggest single difference to daily usability inside the cab. Running apps like Newtracs or Wiki Camps directly from the unit without needing your phone connected is genuinely useful for touring.
The Dash: Hard Plastic, Glare and Heat
The top of the 70 Series dash is a hard, textured plastic that reflects light directly into the windscreen on bright days and radiates heat into the cabin in summer. After a few hours it becomes noticeable. Toyota has not changed the dash material across the production run in any meaningful way.
A replacement dashboard is the way this gets addressed properly. It is a complete dashboard assembly rather than a cover laid over the factory one, wrapped in Italian Napa leather or Alcantara and moulded to the factory mounting points, so it deals with the glare and the heat absorption at the same time as changing how the whole cab feels.
Door Trims, Storage and the Missing Armrest
The factory door trims are flat, hard and offer minimal storage beyond a shallow pocket. There is no armrest from the factory. On a long drive, the absence of somewhere to rest your left arm against the door is a low-grade irritation that compounds over hours.
Aftermarket armrests that bolt onto the factory door panel using a magnetic mount system, requiring no drilling and no permanent modification, are one of the simplest comfort improvements available. Door pod upgrades that add speaker enclosures with proper grilles and integrated USB-C charging also address the storage and connectivity gaps in one piece.
The Shifter and Gear Knob
The factory shifter sits low and requires a reach that is awkward for taller drivers, particularly on long runs when fatigue sets in. The factory gear knob is functional but nothing more. A 2 inch gear stick extension moves the throw into a more natural position without altering the factory appearance, and an aftermarket gear knob improves the tactile feel of every change.
Noise and Cabin Drumming
The 70 Series is loud. Not loud in a performance-car way, loud in a wind-roar-and-road-drum way that wears you down on highway drives. Toyota fitted very little sound deadening from the factory and the basic door seals do not help. There is no elegant fix here. Most owners who address it do so with aftermarket floor mats, improved door seals and targeted deadening on the firewall and floor. It reduces the problem rather than solving it. Be realistic about expectations.
Switchgear, Accessories and Phone Charging
The factory centre switch panel has always had blank switch positions, which most touring owners fill over time with compressor, light bar and fridge switches plus UHF wiring. The result is a tangle that accumulates. A switch panel with an integrated wireless charging tray, designed to fit the factory switch panel location, tidies this up while adding fast charging without cables across the centre console.
Where to Start
If you are only going to do one thing to the 70 Series interior, address the steering wheel first. On a pre-2017 build that means pairing the wheel upgrade with a cruise control kit, because you are solving two of the biggest daily frustrations in one project. On a 2017 to 2023 build where cruise already exists, the wheel upgrade and its controls module alone changes how the cabin feels on every single drive. On a 2023 facelift, the factory wheel with its buttons is already a step forward, and your attention is better directed at the head unit, the noise or the door trim depending on how you use the vehicle.
The 70 Series will outlast almost everything else you could buy. The interior just needs a bit of help keeping up.
