turn the ignition off remove the key. You have a shift lock button I presume. press shift lock button and you can move gear stick through gears without any issue of vehicle electrics being on. The climate controls i.e. two figures for front and back may show, but removing the connecting plugs wont cause any issues. you may get engine management light coming on when you first reconnect everything, but this will go once you have driven car a couple of times. On mine best position was "N" made it easier when replacing facia when completed job

 

Thank you it helped

In 2010, they incorporated the tv tuner inside the headunit, the earlier one has the green connector for the external tv box

In this video I can see he is just pulling it out but it's far to understand how 

I've been following this thread with interest, but the main thing I've learned is it's almost certainly beyond me to try it myself. I've got the 18 speaker surround model too and it's quite hard to find information on how to upgrade it, or even someone willing to have a go.

Hello Andy,

 

Welcome to the Forum.

 

There are many of us that share your reluctance !

Hi Andy Welcome, It does look daunting and with so many videos it can become over bearing. There are a few guys on here that fit them and they do a brilliant job. Ben is one and I am sure Rojie could mention others. I try to help where I can but I am no expert I usually go off my own experience as I am a techy. I like to try to do things myself and so far all as worked out fine for me. However I would first suggest asking the guys who fit them if they are near enough to you.

I don't feel confident in recommending any 'fitters'of Head Units, except Ben Hau.

 

To be clear, I am  NOT suggesting any other fitters are not entirely capable; just that I wouldn't know if they are, or not.

I have no intention of 'upgrading / replacing' my head unit, so it is not an area of knowledge that I have.

 

I do know that many installations are entirely successful, whereas some, regrettably, are not.

 

My main use is the camera the facilities. I use a PC (with CD/DVD) and Bose for 'entertainment'.

 

We have some esteemed members who are far more experienced in this arena than I.

Hopefully they can make some suggestions for you.

Sorry to assume Rojie I just thought with you being MOD you would know who's who better than me.

It is an antenna port, on that model in not so sure, it could be tv (on the MD units, a TV box was fitted under passenger seat)

I don't want to get struck with a copyrght complaint, so have complied with sharing less than 20% - this shows the socket letters and pin numbers.

Interestingly, should be able to use the inbuilt microphone, with some careful testing (socket D pins 4,5,6,7,20)

 

Hi Chris,

I've got all the non JDM wiring diagrams,

But I am failing to find the source of these Japanese head unit diagrams you've posted.

Please can you tell me the file name of the PDF or ISO or whatever it was how you found them?

I'd really love to get my hands on that document as I'm trying to wire up the roof monitor to my head unit.

Thanks,

Matt

You have a copy of the CDROM?

 

There are two schematics, based on premium sound (18 speaker) or super live sound (11 speaker)

 

If you have 2008 >2010 you will have a green connector on back, as the Japanese TV tuner connected to this.

2010 > onwards has the TV tuner built in to headunit by removing the minidisc player

@Chris.ac Yes stupid me, I've found some diagrams.

 

I don't have a copy of "the CDROM" though whatever that is 🤣

 

And I don't have any diagrams with Japanese on them, mine are all western language ones.

 

I've got everything working on the Android headunit like steering wheel controlls, reverse camera etc etc, it was all just plug and play with this adaptor box... not a single wire had to be cut or butchered which was somewhat amazing!!

 

 

The only thing that doesn't work is the pop out roof monitor in the back, but that is because the kit does not connect to the connector "K" as marked on your picture as "A/V Aux", and looking at the wiring diagram its is some sort of Composite Video signal.

I'm going to refit the original headunit , then bell out the signal wires for the monitor, and get my oscilloscope out on the job to see how it commands it to pop/fold up and down.

With these android head units you can buy a USB connected device that creates 2x RCA video output that clones the monitor screen to the RCA outputs. If you search on ebay for "USB To CVBS RCA Video Cable 2 CVBS Output USB To AV Cable for Android TV Player" or just "USB To CVBS RCA Video Cable" they are out there for £15 ish.

And the head unit already has the installed app to run the video output function here from what I can tell....

 

 

With two little girls, having the rear monitor working is mission critical in this fun bus.

It is a shame this topic is in the wrong section of the forum... its some how in the 2002 to 2008 area but this is all for ANH20 or GGH20 vehicles that are 2008 till about 2014.

I think I would like to ditch the rubbish chinese microphone and use the factory Toyota microphone that's up inside the mirror/interior light assembly.

 

I found a few pages talking about using Toyota mic's on other models, and the have the same pin numbers and labels.

 

This page is very good, and there are people in the comments saying it works well

Just pins 4, 5 ,6 and 19 - looks easy

The connector k is an input to the headunit.

The signal out to the rear screen is void connector c I think.

Send me a pm with an email address, so I can forward a scan of the Japanese wiring.

The English versions you can find online are based on export models of the 20 series, as used in Russia, hongkong, etc, they usually had lower spec headunit/amplifiers

Excellent find.

I had wanted to do this mod, but never got around to it, the Toyota mic is pretty decent, when I tested it from the diagnostics menu

[threepot]

Thanks for the help with some info Chris! Utter superstar!

So the monitor is electrically plumbed like this is seems...

 

 

So from the head its using....
 

F12(B) Pin 4 VMTR   (Grey) - Little 8 pin plug, likely monitor activation

F14(D) Pin 1 SigGnd (white) / Pin 2 NTSC (black) / Pin 8 Sheild

F34(H) Pin 1 GVIF Bus  - some optional Digital communication signal

 

 

Notes Translated From Monitor "(F) Television display ASSY"
Optional connector
S2 (B), S3 (C), S5(E), S6

*17:With television display ASSY
*18:No television display ASSY
*10:With television display ASSY without sliding roof
*11: Television display ASSY with sliding roof included

 

And I think we can basically ignore all the MO's and MI's as they are MOST signals that send audio to the Amp, SLDI/SLDO are shields, and WUO/WUI are MOST wake up lines.

 

So I think if you send an NTSC signal as the monitor, and then from some Toyota Landcruise tech documents I found it talks about the media system with the dual monitors in the back of the head rests...

 

Tester Connection Condition

Visual mute signal When image on Display switches
VMTR to Body ground Specified Condition
4 V or higher → RSE is playing
Below 0.7 V → Source is changed

 

So I think that must be like a 5v is sent to the monitor to enable it.. "visual mute" would be monitor disabled. Maybe it flips it in and out.

 

I'm so stoaked, even though its been a hectic week I'm going to get out there and test this out now...

 

[threepot]

Well look at that....

 

 

All it actually needs is the Pin 1+2 on F14 for the NTSC video in signal.

 

Then if you press the G button on the remote the screen pops out anyway. 🥳

Awesome work.

I'm still using original headunit, so never got around to figuring that out, well done!

[threepot]

I've just done my 3rd MOT since I imported it. 3 years of either Radio 2, Fleetwood Mac's Rumours or Silence!

 

Oh and if the kids are in the car Finding Frigging Nimo or Aladdin.

 

It was time for a bit more variation in my life, and I tried 2 different a band expanders but the reception and sound quality was pretty poor.

 

Year ago I imported this other head unit from Malasia that supported Engiish and full radio frequencies, but after many nights of messing, came to the conclusion it didn't support the amplifier and MOST setup from the JDM van. Cost me a fortune to import that too.

Hi all. Can anyone help me with a replacement head unit for my Toyota alphard ANH20W 2008/9 2.4. having a lot of conflicting info regarding plug n play. There seems to be a lot of differences between the cabling and ports on the rear of my original sterio. Any help would be greatly appreciated. As you can see I've added pictures of the back and front of the head unit which may help.inn24🐉😎

Hi, I have managed to replace this head head unit with a generic android head unit. It wasn't entirely straightforward so here are the details in case they're helpful for anyone else.  

[Dave_R]

The original head unit looks like this. Back panel and identifying part number 26041 on the front. My car is a 2009 Vellfire GGH20W Japanese import. It has the high spec head unit with GPS navigation and hidden Minidisc player, but does not have 18 Speaker sound system. It does have an amplifier under the front passenger seat but I can only see 9 speakers - maybe there are two more somewhere. 

[Dave_R]

After removing the head unit the connectors look like this. Note that not all connectors on the head unit are connected.
