Hi! Did anyone managed to synchronise the reverse camera's guidelines to match the spinning of the steering wheel?

Any spare GND on any connector on the head unit will do.

Geralt, thank you so much, you are a star! Connected the swg to ground and ..... all working fine now!🙌

2 is ILLumination DETection. i.e. This input triggers the illumination of your head unit when you've switched on your vehicle lights.

 

Not 100% sure but 4 is an output to an active antenna amplifier.

 

Just checking. The XTRONS label you posted is the new HU you're installing, right? When you asked the question originally, I thought you didn't have the pin out information but since you do you can just ignore my picture.

 

Yes, the Xtrons is the new one. I have similar pins on the new HU and I was wondering what are these for. Also, on the old android, I have a RCA labeled video out, and the roof monitor is mirroring the main HU. I cannot find a similar one on the Xtrons, although manual mentions about this function ( but not how to connect the devices). Can you see a potential video out on the Xtrons pin out?

🤣 We both posted in the same time!

Without SWG connected in some way it just isn't going to work. It needs it to measure the resistance and determine which button has been pressed. 

I understand this and yhis is exactly why I am asking where to connect it. I do not see any reference of it in other posts here and nothing on the pin names from my head unit

Looks like it could be this pin out:

 

Hi Geralt, what are pin 2 and 4?

Hi Chris, I found all three wires, SWG, SW1 and SW2. Thank you so much. I have connected the sw1 and sw2 to the coresponding wires on my 16 pin head unit connector, but still nothing. I am sure that I have to connect the swg wire too, but I don't know where. Do you have an ideea, please?

Sorin, the lowest spec audio system has 8 speakers.

2 corners near windscreen.

2 drivers doors

2 sliding doors

2 rear seat sides

 

I assume you only have buttons on the left side of steering wheel?

 

Try here. Full diagram.

Thank you Chris, I am looking at it now!

But yes, from all the wiring diagrms i have, the buttons shouold be plug and play, as there are only really 3 signal wires and the head unit is just detecting different resistance levels when you press buttons, to determine which button was pressed.

Chris, do you know where I can find these 3 wires? I don't have them in the harness at the back of the head unit and I want to look for them at the other end, but where is the other end of the wires?

I'm not so sure now. @Voodoo101 thinks that volume etc comes over CAN.

I don't think I'm helping here so think I'll bail. You need to find someone with Gen 2 experience. Sorry.

Don't worry, thank you so much for your help. Maybe @Chris.ac can step in and advise?

Sorry, that's garbage. I do have guidelines but they don't move for reasons mentioned above. My older van doesn't have CAN anyway.

All the cars have Can comms. I am pretty sure that there is a way to get them to talk over the Can protocol.

Connector C is not in use, the 2 Can wires. I do plan to connect them, I have to think at a way to plug in to the Can lines.

So they are pins 6 and 7? Just making sure.

Yes. Also, when you are reversing, are your guide lines moving in corelation with your steering wheel moves? I mean, if you are turning the steering wheel to the left, are your guide line moving to the left too?

Hi Sorin,

 

 

The two 2SW wires you mention, can you confirm which pin numbers they go to and what their colours are? The photo is not clear enough for me.

In the previous photo, the 2 SWC are the short ones pointing up, a brown and a brown+white. They are positioned on the 16 pin connector as in the pic attached, pin 6 and 7.

Did the SWC work with the old unit?

Hi Geralt, thank you for your help. In the 16 pin connector I have the 2 SW wires, but are connected to nothing. This is why I want to find where these wires are coming from and connect them. I bought the car with an Android and the SW buttons were not working. You can see the SW wires in the pic.

Hi all, I am writing to ask for your help about the wiring for the head unit. I have a 2012 Vellfire 2.4 petrol. When I bought it, the head unit was already replaced with an Android. When I wanted to change it with a better android, at the back I found a total chaos in the wiring, as you can see in the pictures. My car has only 1 speaker in each door, so 4 in total, plus 2 small Pioneer fitted on the A pillars. From all those wires I noticed that the ones for the Steering Controls are missing and I don't know from where to bring them to the head unit.  I also have a grey connector with 4 wires that I don't know what is for, but I suspect that is for the rear camera. It doesn't connect to my head unit, but my rear camera works!

Please help if you can!

Best wishes to you.

 

Chris, by any chance do you know what is this connector from the back of the head unit? It does not fit in the new Android and I suspect that is the steering wheel controls, but I wanted to double check with you!

I finally managed to programme a new key fob for my Vellfire 2012 with Techstream. The whole process is a bit annoying but I manged to do it in the end. If anyneeds help, I am more than happy to help with details!

This is the fob you need for your hybrid.

You can check the listing,  it tells you the circuit board number

Thank you Chris, now I understand how to match a key to my car, by the pcb number! You are a life saviour!

@Chris.ac the eBay seller you pointed to get cable and software from seems quite decent and helpful. Many thanks again 

 

So I understand the way to go about it is 

1. Get cable and software 

2. Get key fob and program it 

3. Get the key blade cut.

 

I've bought the cable and software 

https://www.ebay.co.uk/itm/124808047632

 

Next buying this fob https://m.aliexpress.com/item/1005003598907017.html

 

They can cut the key blade too 

https://m.aliexpress.com/item/33030748490.html

When we have all three, we might be in business. Best part of the eBay seller seems genuinely helpful if any issues with software. I'll feedback here and recommend based on my experience once I'm through this.. 

 

Hi Teekay, I have a question: I bought recently a OBDII that I can use to scan my 2012 Vellfire. My phone connects to it via WiFi and I have an mobile app. https://www.eurocarparts.com/p/streetwize-obdii-code-reader-for-android-and-ios-553999810?gad_source=1&gclid=CjwKCAiA3JCvBhA8EiwA4kujZt5VBcVRzw1spzBEo3PjEV-_5JrKMRPyZnSpGxpf-RFqik5o2rGPARoCAL4QAvD_BwE . Is this the same with the VCI cable? Can I use it with the Techstream software?  Also, what is the difference between the keys with different frequencies, 312, 313 and 414 Mhz? I need a 4 buttons key and I am not sure which is the correct one for me!

Thank you Chris, very helpful! In the meantime,  I looked through other posts and websites and l I found this one at Argos, I bought it immediately and also used it to change the settings for opening and closing the windows with the smart fob. I was happy to see that they have it in stock at Argos but not at EuroCarParts.

I set the sliding doors to single beep when closing, and all Windows open close with long press on external door handle button or remote

Hi Chris,  what are you using? Can you please share a link to the OBD?

So I have my roof monitor install properly working and tidy installed. I just cut one of the yellow plugs of the USB adaptor lead and soldered two pins to the wires, then heat shrinked it all up. This then just slips into the Toyota factory plug as per the attached pictures.

 

 

 

 

 

 

 

 

Hi, can you please share with us what is the polarity of the wires?

Hi Chris.ac. Can you please share with me the wiring for the head unit and the roof unit? I just bought a 2012 Vellfire and it has an Android but many features are not working, like the roof unit. When I removed the front unit, there is a large number of wires thare are not connected or are cut out from connectors, a total mess. A correct wiring diagram would help me a lot as I am an robotic engineer and I should solve them. Many thanks in advance!
