Mobile phone hotspot, if you have a data package as part of your contract, is the simplest option.

I've seen these on AliExpress, and also blindspot/side cameras that come with two screens you fit to the a pillars, so it's like those new truck digital mirrors

Easy easy to check. Does your rear wiper sit under the roof spoiler? 20 series. Does it attach to the tailgate below the glass? 10 series.

For the alphard 2gr, you have to bleed it with the coolant system closed and pressurised. Open bleed valve on top of engine block, to up coolant into expansion bottle until you see coolant come out of bleed valve. Close bleed valve. Fill coolant to the upper B-line marked on expansion tank ( the left side of tank looking grim front of engine) Seal the cap on expansion tank. Start engine and run it at 2500 RPM until you see coolant start to enter the top of the tank. You will see bubbles, keep the engine running at that speed until the coolant turns from cloudy back to red. Done. Switch off. Leave to fully cool down, check if coolant is between the full and low mark, top up to between these marks if necessary. If coolant has dropped below the low mark, repeat.

Did the American 2gr bleed involve radiator cap and a tube from the bleed valve running back to a coolant funnel?

It's AC. Like the Japanese domestic electricity system

Everything is working perfectly now. Even in this recent heatwave, temp in traffic doesn't rise more than 89c You must follow the Japanese air bleeding process. Trying to follow any of the YouTube videos for a 2gr-fe will fail. I took several days retrying to bleed air, and reach time I thought I had completed it, as soon as the car went up or downhill, the temps would start climbing past 100c.

Yeah the extra connector on the PCB is because some head units have a different size Flexi. The usb is for removable media if you are using the video or MP3 player instead of the carplay

Glad you got it fixed. The relay box is an absolute bugger to get out, but the solid state relay was the problem for me, too. I can understand that they form part of the security system, but Toyota could have made these more accessible.

Auto parking still works

Reverse (overrides carplay)

My extra Flexi

I then routed the Flexi out of the same slot as the big brown one and tied it out of the bottom of the headunit case through one of the slots in the case.

One of the onboard flexi goes to the LCD, the other is the touch panel. I thought I had my electronics screwdrivers on me, but they are at home in Devon. I believe it's the one on the right of your first image, the one that has pins called TP for touch panel.
