100 Series NAV Delete – True Standalone HVAC Solution (OEM+)

[akfjord]

Thanks for all the work on this!! Excited to see it come to be. I’d be a buyer for the v2 finished product for 2006 LC

Progress Update

Core hardware direction is now locked and we’re transitioning into schematic and PCB.
v1 uses a dual rotary setup for TEMP and FAN (with push-off on fan), supported by dedicated physical buttons for AUTO, A/C, RECIRC, MODE, and FRONT DEFROST. MODE cycles through vent positions with indicator feedback.

Feedback is kept simple and OEM-focused: a small center display for temperature only, mode indicators (Face / Bi-level / Floor / Defrost), a fan level LED bar, and active-state indication on key functions.

System behavior is designed to mirror factory AUTO climate operation, with proper integration into OEM dash illumination for dimming.

With this layout does the temp knob center at 72 and turning it changes the auto temp?

So awesome I will for sure get this. 2003 LC

One question, and sorry if I’ve missed the answer, but how would an aftermarket head unit fit? Being as there are no adapters for these.

I, too, am interested in the answer to this.

I'm happy to be an early adopter and supporter for a v1 on a 2007 land cruiser

 

[StickyNotorious]

Please put me down for one for 2004 LC. Can’t wait.

It would be worth making the temperature display selectable between Fahrenheit and Celsius to cover global markets, maybe through a key press combination.

Edit to add - now seen a few other have commented this!

 

[D Fitz]

I will buy one when available, preferably V2. with an Auto function on AC.

 

[SquareOne]

I am definitely looking forward to this when it's available for purchase.

Moved into PCB design

Brought in dedicated automotive PCB experience for this phase. Hardware locked in now with a focus on clean, stable operation in-vehicle from the first revision.
Once boards land, it goes straight into bring-up and in-vehicle testing.

Progress has been steady behind the scenes

 

[willc]

Just chiming in to say… if you crack this for all of us who dislike the stock setup, you’ll be a hero

 

[Anarchy]

Major components are placed and routing is in progress, with heavy focus on power distribution, grounding, and noise isolation for real in-vehicle conditions.

Designer comes from ultra-high-performance automotive electronics, so the expectation here is production-grade reliability on the first revision.

@LJE handling initial 3D Scans & CAD for physical constraints and fitment.

LX gets a true OEM-style integration into the cassette slot.

LC is slightly different, will require a faceplate to adapt cleanly.

Both will function the same.

Initial small run being planned.

 

[implayaz9]

Quick questions. Why would LC need a face plates vs LC being in the cassette slot?

 

[Manhattan]

I've been following along and think (thought?) I was keeping up. But can you briefly explain what happens to each of the these sections - since the Toyota engineers decided to spread controls all over the place. Also, THANKS for taking this project on!

The only thing that @Anarchy is changing is replacing the stereo in #5 for HVAC controls.
Everything else will be unchanged. However, this WILL require you to install an aftermarket head unit, or relocate the stereo unit.

what is going on with the theft ecu if that's the case?

Sold 2005 lx - so excited

Where would the aftermarket head unit go?

 

[seanz0rz]

I'm in for one.

 

[Dutch178]

Where would the aftermarket head unit go?

You would remove the nav. screen, and place it there. There are several aftermarket kits that would fit around the new head unit and fill the gaps to the surrounding OEM trim.
