If you go on to AliExpress, and search for Toyota alphard MOST adaptor/interface, you'll find dozens of listings for the wiring harnesses Here's the block diagram for the headunit.

I use a android auto/carplay external box that connects via the aux video input and the oem Bluetooth for audio. Less than £200, if you fit yourself. You open up the screen and add a connector to the touchscreen. The rest of it is plug and play. This means you retain all original functionality, with the added functions of android/apple system. If you want to go aftermarket headunit, you will need a MOST decoder box for the connection to the amplifier, and a gvif adaptor for the cameras. Although you will be able to see the 270 cameras on an aftermarket headunit, i don't think the auto parking will work because you won't be able to interact with the onscreen interface, the video freed will be essentially 'dumb', whereas using a box like i do, you still have full use of the IPA system ( to be honest, you'll probably never use auto park, because it's quicker to just use the cameras as an aid and do the steering manually)

Yes. Some of the non sunroof utilise a different design speaker in the roof. This must be an 18 speaker system. The amplifier is a 16 channel 640watt (16x40 watt) system, and a separate active powered subwoofer.

If you want a 2.4ltr, yes.

The confusion arises because some imports are actually 'export' models from Hong Kong. Are you sure it's just 4 in rooflining? If it's the 18 speaker system, there are 6 in the roof, 2 in rear and 4 between the two sunroofs ( these 4 near the front can have split audio sources, eg, radio/bluetooth for the front passenger and driver, and the rear 4 roof speakers outputting cd/dvd for the rear passengers. The base model has 8 speakers, the super live has 11 speakers and the premium has 18 speakers. The 11 spk has an amplifier under passenger seat. The 18 spk has a larger amplifier under passenger seat and a subwoofer under drivers seat. The 270degree camera has an IPA (intelligent parking assist) ECU under passenger seat, that takes inputs from the sonar, and the additional two side sensors on the front bumper. The front and side cameras connect via this ecu. can you see if tweeters are fitted on the sliding doors? They are located near on the front trim of the windows. In any case, your headunit model suggests an external amplifier. You can buy an adapter that converts an analogue output signal from an aftermarket headunit into a digital signal the amplifier understands., and therefore retain the amplifier and existing speaker wiring. I can share the block diagrams and wiring schematic for the ipa and headunit

Yeah, just front bumper and rear lights, with some trim inside. Its a really basic model, things like AFS on the headlights, auto rain sensing wipers, auto folding mirrors are missing, and it has the basic 8 speaker setup with an aftermarket headunit. It looks nice and shiny, but i think for the price you are missing out on some tech that should really be standard. Maybe I'm just a snob, but i would totally miss some of the features.

Prime selection 2 is just marketing gibberish for some coloured trim, upholstery or tinted headlights. The 240s part is what counts, so it's a standard model. Models for the 240 are 240x basic model 240s standard 240g high spec I would say at this point (2025) this couldn't really be more than £10k, unless it's been really well looked after and had something to make it stand out from the others, at this point adding a few k and buying a 30 series is realistic. Consider i bought a 350G for £12k in 2021

I don't know for sure, it's possible there is more than one type of wiring loom. Its only 2 bolts to remove in order to check

Yes, unfortunately. Although the resolution does tend to much better in the kits, you have to consider the factory ones were specified in 2008, and cameras are now HD or better. In the 2014 models, they did actually have a full 360 degree, with a camera on the driver's side, i had thought to buy one of those wingmirrors, and fit upgraded cameras into the existing spaces, utilising the wiring already in the oem looms, the other option would be buying a new ipa ecu in order to use the official Toyota 360 solution. You can use the original cameras with modern headunits, you can buy adaptors on AliExpress. Going oem vs aftermarket comes down to cost and patience!

There are two wires. A parking brake, and a speed sense wire. Please add a photo of the back of the unit and I'll post the correct wires

At this point, it would be cheaper to buy an aftermarket 360 camera set and controller, and connect it to the new headunit. If you do want to use original, the wiring should still exist behind headunit. I can attach the wiring schematic

Do you have electric middle row seats? If not, you'll have a free 12v connector near the bottom of the b pillars, you'll be to remove the trim, but you could essentially hide the router behind the trim or beside the drivers seat

There is no 'reset' in the official Toyota process. At most, you'd connect via the obd in order to do a transmission fluid temperature check.

The dome fuse is the correct one. There is no relay. What you will have is several other fuses working in conjunction with the ECU, and the ECU in some cases provides the ground logic. I've attached the illumination wiring schematic. IL.pdf
