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
