3rd Gen Tacoma HAI's Cable Assy. for Front/Rear Camera Anytime, Navigation Override, Smartphone Mirr

@tonered - thanks. Now I see those cables are already included in the HAI cable. Can I assume it doesn't matter which order they go, connecting to those two switch cables (green, and red1)?

Also does anybody know what year Tacoma changed design, where they can no longer use this assembly? Earlier somebody said it doesn't work on a 2020, and @tacofish is asking about a 2019. Mine is a 2018. What's the latest model confirmed to work?

Thanks again!

 

You're welcome.

There is no order. You're just completing a circuit.

It will work with no problem on a 2018.

 

I have another newby question! I'm planning to install tomorrow. Reading the forum, I notice several recommendations to turn the override switch on and let it sit there for a few hours. Explanation is it takes a while to synchronize, and for navigation to start working properly.

My question - how can I tell if the switch is on or off (either pre, or post install)? There's no indication on the switch itself. I have a meter, but not sure how I would test the way it's assembled. I'd like to know for sure when I'm actually turning it on.

Thanks again!

Good question. First, it will only start updating while you are driving. So, don't worry about letting it sit.

If you have ACC On and see the A/V input selection on the HU, then it is in the On / override position.

For the first little while while driving in override, it will freeze the nav display updates. When it does update, the refresh rate of the updates will be a bit slower. @BigWhiteTRD noticed that. I think it was about three per second versus the normal of about six or so per second?

Still, I have had mine in override for months at a time with zero issues.

 

Wow that was fast - thanks for the info!

One more question please. Original post explains what to buy for the described functions. I purchased what was recommended (Mirabox, front camera, RCA couplers). Now I'm planning the install. The assembly comes with 3 RCA connections; red, white, and yellow (I assume the yellow is for video). If I connect the front camera *and* the mirabox, won't each require a video feed? Not really clear yet how I'll get video from the camera to the assembly unless I use that cable (with a coupler). But wouldn't then leave a need for video feed from the MBox?

Sorry for all the questions I'll get there soon!

You're welcome!

I only have the basic override harness and front camera video only on the yellow input. I do believe with that, that there is only one video input possibility without some type of switch.

And, yes. The L / R audio input would be for the HU A/V source option.

Unfortunately that is all that I know as I do not have a MirrorBox.

The harness has been flawless for about 3yrs now.

 

To add to what @tonered said, worst case if you can't tell which is which, drive around and watch your location on your map. If you're "not moving" then the override is on, or the truck thinks you're not moving. Flip the switch and it will catch up to you shortly. There isn't really a need to let it sink in so to speak for a few hours since you're essentially just moving or sitting still. I don't have the HAI kit but I did install the Nav override with my ABC kit and I don't see why it would be different.

 

Thanks for your replies! Another question re the rear-camera switch. I assume I don't need to connect the other wires that came with the switch...unless I want the switch to light up? I guess would be nice but not really important.

 

I'm assuming that you are talking about an AOB or CH4x4 switch harness? If so, then no. Just the switch circuit is fine.

That said, I put my switch in a hidden location (near the steering tilt lever). It wasn't worth taking up a switch panel slot.

You can see mine somewhere in this thread.

 

Selling mine, pm if interested

 

My truck is a 2016. Does this still work with 2020's? My buddy just got a 2020 - if it works I may point him to you. I love mine.

PS: are you replacing it with something else? When I got mine it was the only game in town. Now there are other options out there. You can PM me if you want.
