Its the same tech you can get in Phillips hairdryers. It is part of the climate control, and controls the ioniser. Helps to remove pollutants/pollen.

I forwarded links via email

It's on the right side of the map light area behind a little slotted grill. It works quite well for me, maybe you need to increase the mic volume on headunit

You can set the behaviour of auto locking and unlocking doors based on shift selector on P or D, via a simple combination of holding the lock or unlock control whist depriving ignition on, in the relevant gear. It's in the user manual

I'm no help here, fortunately i have only ever needed a wheel bearing on an older Toyota to be replaced. I need to find an AC specialist, I've started to get the green flashing light of ac doom.

You can download a preconfigured virtual machine for use on windows. You can find clear instructions on the Toyota ih8mud forum https://forum.ih8mud.com/threads/how-to-techstream-in-5-minutes.1034923/.

Are you able to access the files? They are on Google drive, but your btinternet email cannot be added as a trusted address. Hopefully the direct link works

Will send a link to the diagram.

Could be aftermarket alarm or wireless door entry. What keyfobs do you have?

What? Would be a keyhole drivers side Post photo of drivers handle, previous owner may have fitted a blanking plate that is removable

Left column is front, right column is rear.

Well done. The rear fog cheapo switch triggers me everyone i see one, so glad you prioritised that 😂

I found this DA-G2.Standard MOST25 - mObridge UK https://share.google/HhuTvhUiKk9jZjEH6 I can't recall if the alphard uses most25 or most50. Perhaps this company can advise?

Diy route, you can buy (about £ 160) from AliExpress or alibaba, a generic Toyota compatible box. The one i bought a few years ago used the phono input/aux input and i used the kit to splice into the touch screen on the headunit (there is a small switch that flips between the box input and the original headunit input, for navigating around the screen. I've not found the same supplier, but there are a few around.

I don't think I've seen an adaptor that takes the MOST signal from the headunit and converts to an rca. The closet i have seen is an amp bypass adaptor, or the converter you linked that allows you to retain the amplifier (both assume headunit replacement) The other auxiliaries like auto parking and cameras and rear screen use GVIF ( gigabit video interface) There must exist an adaptor that converts most to RCA, maybe another Toyota model?

The 20 series doesn't use fibre optic, although aliexpress refer to it as an optical converter. Most doesn't use the canbus, it's a separate network. The headunit does all the work, so of you are replacing it, it's irrelevant if you are bypassing the amplifier. That adaptor is used for aftermarket headunits to convert their analogue outputs into a most signal to the amplifier. If you are removing the headunit and amplifier, you don't need that converter

Dashboard illumination control. Odo memory switch. Camera view selector ( switches between front, rear, and side/front) Next row Traction control, rear roof illumination brightness toggle. Parking sensors on/off Next row. Rear foglights. Front light auto turning mode ( your dipped beams move to the left and right when cornering. Wing mirror fold control ( centre position will fold and unfold with locking and unlocking doors.) switches to the left. Auto parking (i can add a link to a translated English manual that covers this and the headunit) - yes, this model can parallel and reverse park automatically Sliding doors power ( to switch them into manual mode, if want to for some reason. The toggle button is aftermarket, may be linked to additional interior lighting or daylight running lights, you'll have to check.

Not sure to understand the point. This kit is to enable a non oem unit to connect to the oem amplifier. If you are bypassing the amplifier, you don't need this kit. Maybe state what it is exactly you are trying to do? If you want to use the connections to the oem speakers directly, the sockets at the amplifier are wired like this. If you want to see the block diagram for how the most system connects to the sub-components, use this file Headunit block diagram.pdf

You can also use the button on the steering wheel to select the eco display on the dash, so you can see how hard you are accelerating. The eco button is really just the opposite of a 'sports' button that some Toyota have, it just softens the accelerator response. I turned off the eco light as it was distracting flashing on and off.

I believe the folding when locking is an aftermarket module they may have installed (previous owner). You can buy these modules on AliExpress. The auto tilt mirrors are not installed on every model, you appear to have a base level vehicle. The auto tilt requires the mirror that has the additional motor wiring and hall effect sensors, often combined with the electrically adjustable drivers seat and seat memory ecu. If your driver's seat is manually adjustable rather than using buttons, you will not have auto tilt mirrors or auto folding. The fold mechanism is just holding the signal at ground, which is what an aftermarket module will do in combination with the central locking signal.

Ah ok, you do not have the more advanced auto mirror system installed.

You need to purchase a generic/Toyota compatible box from somewhere like AliExpress. You will need one that has an rca output. The box will usually come with either an external controller or a touchscreen interface board. I opened the screen and used a ribbon cable to connect to the touchscreen that has a switch to select of the touchscreen settings signal to the carplay box, or the official headunit. I interrupted the parking brake signal to the headunit so that the aux video remains on when car is in motion.

When i have insert dvd. It automatically lowered on both screens, i can use the dual option to only show it in rear, if disk is switched off it mirrors the front. On yours the cd/dvd is greyed out which means you dont have a dvd inserted out recognised

In the image, you have it set to hdd, which is the internal harddrive that stores mp3 chips of music cds you insert into headunit
