Does anyone know any other alternatives to get these made? It’s my understanding JerryB is no longer making them (if this is not correct let me know)

Is there other companies that we can get these made from? It seems like there are multiple people looking for them. Could we give them Jerry’s specs and have them made for a Group Buy?

Are there other OEM harness available that can be spliced or modified to work?

Source a RHD unit with the pigtails attached?

Any alibaba suppliers have them?

If you have recently done the Nav Delete what are the best options without getting all the tools to make my own? Thanks

I can get all of the parts shown in this pic for those wanting to do a swap. The parts marked in yellow are what's needed for the LC and the LX will also need the vents and panels that are not marked. The parts will come with the plugs and wire pigtails for your wiring. Send me a PM if you're interested and we can chat.

Hey Bud, there is a whole forum on what is needed. I'm actually working on making a harness. I have obtained all the parts and will be working on it this week/ I hope to make a video detailing the installation once I get it figured out.

Here is the main forum:
2003 and beyond nav delete
hi, were you able to complete the installation and make a video? would be very much appreciated if you could share any insights...thank you
 
I’m "actively" developing a standalone HVAC controller for 03–07 LC100 / LX470 nav-equipped trucks.

The intent is straightforward; retain the factory HVAC ECU entirely, replace the nav-integrated interface with a dedicated CAN-based HMI, open the dash for a standard double-DIN head unit.

Working on vehicle-level body CAN capture, identifying HVAC command vs status frames, handling rolling counters, timing, and periodic transmission, verifying behavior via CAN injection.

I am approaching this as a production-grade embedded system.

No timelines yet.

If anyone has documented HVAC CAN data they’re willing to share, feel free to reach out.

I will be one of your first customers!

Sounds perfect. Almost pulled the trigger on a used non-nav conversion from Pakistan but some iffy reviews and a need to make a harness dissuaded me. This sounds like it would be a great solution.

I would be very interested in this as well. Do you have any idea what the price will be?

This sounds like the ideal solution! I was thinking about this the other day - it seemed 'doable' based on my high-level research, but my engineering skills certainly lie more towards physical hardware than electrons.

Let me know if you'd like any help developing bezels/faceplates/etc for the conversion -
I've gotten pretty good at getting a factory-fit on stuff and would love to help out.

Making the harness isnt too hard. I did it and Im a total noob beginner. As shown in the video I posted. But, I did make it work and have had zero issues

This is an awesome project. I hope it comes to be. Toyota missed the mark when they integrated everything.

The availability of Non-nav kits has dried up. Shahab only had 5 kits left a few months ago and I've had two people contact me for install info, so Im guessing those last ones are gone. This project is the only real way for anyone else to add an aftermarket stereo to the 100-series. Those Tesla screens are s***.

Anarchy, If you collaborate with LJE, you may have a winning product for a decent price.
 
I do this for a living, I already have the tooling. I could make the harnesses, but it seems the market may not have the supply for everything else. If Toyota didn't have so much in the kit NLA I'd probably make a bunch. Seems a one or two off isn't worth the time though, especially if there are other solutions being R&D'd.

The wiring and connectors are available... The components have dried up. The big holdup was the M9 connector, but one of the guys located the source on aliexpress. The updated link is on the video.
 
I'd be very interested in a plug and play option for my '04. I have all the parts, but can't gather up the courage to start. The differences in wiring in the 03 and the 04+ trucks are something I still have to work through as the info isn't as clear as I need it to be.
 
I'd be in for a solution as an 06 owner that could never find the right AC amp part number. All the kits from overseas that I looked into had the wrong AC Amp for my vehicle so I could never commit.
 
I’m definitely in for an 03 setup. The GROM VLine is ok enough after lots of tinkering but still fairly clunky compared to most aftermarket radio setups. It’s not without its daily frustrations.
