How ? What is your motorway speed ?

I'm not sure but, maybe with Toyota Techstream, there's some settings for headlights. It need confirmation (maybe I'll check this WE if I got some spare time).

Autodoc got the good refs for GGH20, if you want to look.

Yes, I love this so much. For those who need, you can just enable google translate on your phone to verify

Pivot answered me this night. For the common knowledge, here is the answer they translated from Japanese to English :

Thanks a LOT for this find. I just emailed them, I hope I'll have an answer.

You should find the USB C outlets on aliexpress, with the correct size. Just measure it and check aliexpress. Yes, read my posts, I linked a video showing exactly where it is.

No sorry, I kept the switch, because I think it's pretty neat to keep my hand on the power usage in the back. You can still use a multimeter to determine which one is what.

That must be that yes black/white is ground, Black is +12. So take a note of how you link them and check before connecting your new plugs.

Yes this is exactly this plug.

I can talk only about Vellfire. I've got one imported from Japan, and after researches, there's English available since the 2012 restyling, not before.

You can only change to english from the 2012 version, when they updated the GUI. Before you are locked to Japanese. As a complement to the previous answers, I personally found (but didn't order by now) those 2 products which seems to keep the original features : https://www.dvdgpsnav.com/blog/toyota-alphard-head-unit-replacement-android-radio-upgrade-navigation-multimedia-system-tesla-style/ and

And you can replace both of 100v power outlet by 12v (converter included to 5v) USB converters (found on aliexpress in my case) for a pretty cheap price, with the exact dimension to fit for Toyota. I just did it, picture joined.

I found it. So the converter is under the driver's seat. It's easy to access, check this : https://youtu.be/uwfSWvKsLec?t=110 Remove the plastic next to the right driver's foot, remove the trim in front of you (check video, I don't have the exact english word), and then you get access to the converter. I checked the wires, when you unplug the connector and watch it from the front, the 2 wires on the left (top and bottom) are the 12v and the 2 others are the ones going to the 2 100v power outlet. I hope it helps

Bonsoir I finally found the converter. It is really under the driver's seat. As I don't have an Alphard I'll not pollute this topic, but in the Vellfire section there's one similar, so I'll post in it !

No. But I finally found the information after some research with the Alphard 1st gen inverter assy part number. It seems to be under the driver's seat (RHD version) : https://www.amayama.com/en/part/toyota/8621058030 part 86210A . Will have to unmount the front seat to access it, it seems.

Well, it's not under the console box in the 2009 Vellfire

Thanks for your answer. I was going to remove the dashboard, so if it's only under the console box, it'll be very very much easier. I'll check this later. Thanks again !

Did you removed the 100v AC converter ? If yes, can you tell me where it is located ? Thanks !

@Rushi Punjani if you are able to find the DC/AC converter, I'm interested in pictures of his location. I currently don't have time to follow the cable from the console box, but if you have it, thanks to share the location

Could you link the special insert from ebay please ? Can't find anything. Thanks !
