Hi Bilal,

 

do you have any instalation videos? I have bought the xtrons head unit and MOST, but i cant get it to work, screen works, but sound and climate controls doens`t. did you need to modify the iso harness at all? i have loads of conectors left loose from the original screen. mine is the original navi from 2007 with mark levinson, can`t seem to find any info online at all

 

thanks 

Did you buy the additional fibre optic unit with your XTRONS head unit? You will need that to make the head unit work with a Navi vehicle

i bought this :

But it the usb lead doesnt seem to fit the optical cable that i have in the car, which is a bit annoying, and xtrons don`t seem to have good customer service 😄

I did create a rough wiring diagram for the XTRONS head unit which I'll post down below as well as the one XTRON have provided, yeah the USB cable was a no go for me so I ended up buying an aftermarket toyota retention cable from eBay.

Makes sense now, the bottom part of the head unit (where cd player is) on mine is completely different. I have 6 connectors or so coming in, thanks for your help anyway!

Hi Ahmed, I discovered first on YouTube your TEYES CC3 setup with Siri voice activation in Apple CarPlay through the steering wheel Voice button. Then I searched for your profile online to see if you've described the process. As I see that you have detailed the assembly here, I have registered on purpose. With the jailbreak thing you had my curiosity, but now with the plain vanilla solution you have my attention! 😉

Can you please expand how to do this? It is my understanding that programmable KEY1 and KEY2 pins on Android head units can only work with the SWC wire carrying an analog voltage that used to exist only in very old cars, before the CAN-bus systems that make these model-specific, non-programmable Chinese canbus decoder boxes mandatory. Said otherwise, one cannot (and shouldn't!) connect CAN digital wires to these analog pins. So how did you achieve this exactly?

Hi Julian,

Apologies for the late reply. I'm not on here as frequently as i'd like to be as i'm usually inundated with messages on Instagram so do try and catchup when I can. 

In regards to your question regarding the KEY1 and KEY2. Your understanding is correct that KEY1 and KEY2 require an analogue voltage. However, you are mistaken about the steering wheel switches being CANBUS controlled on the Lexus. I've worked on many Lexus models even some newer models as new as 2023 and Lexus/Toyota use analogue voltage for a huge number of functions. I have attached two diagrams below showing the wiring schematics of the steering switchpad for both the pre-HDD 2006 to late 2009 model and also the later model with the HDD and USB function. If, you look at these diagrams you will see that the steering wheel buttons are tied into 3 wires. A common ground, and SW1 and SW2. The switches are grouped into 2 groups. One group has the Voice, Off Hook, On Hook and MODE buttons tied to them and the other group is the remaining buttons (excluding the DISP button as that is directly wired to the cluster) Each button in a group goes a resistor to essentially create a different voltage readings which is then detected by the head unit. So in the case of the Teyes mod, all I did is take the single wire for the group that contains the Voice button and wire it directly to KEY1 on the Teyes unit. Then this let me customise the button mapping via the steering control app. I left the other group alone as the default Teyes pre-coded mappings for that is fine anyway.

One thing to keep in mind is that I did not modify the wire for that group on the actual car harness, instead I located the wire/pin then traced that those steering switch wires go to the CANBUS decoder box on the teyes. So, the wire that i was interested in I cut it on the Teyes harness before it goes to the canbus box and I took it directly to KEY1.

Hope that makes sense.

Below are the schematic diagrams.

Not sure why images stopped working. I've uploaded them again below:

Thanks!

Maybe, you have scheme for US car?

I have AWD version car (2008), so buttons on steering wheel are not working with Teyes at all. I hear that US version car have other pinout.

I'd have to check later in the evening when I have access

I have a Lexus IS250 2007 with a Marklevinson Oem nav system

i have bought the Teyes CC3 model B and I have installed 

everything is working well apart from the OEM reverse cam is not showing an image when car is in reverse.

the until flicks over to reverse screen when in reverse but it’s a black screen with just guide lines. 
 

Is there some settings to adjust or wire splicing I need to do as I thought it was a plug and play with the model B option?

any advise, pictures, videos would be very much appreciated

It should be plug and play but I struggled to help a fellow member get it working. Apparently plugging in the OBD cable helps with reverse detection , in the end we just ran a new reverse camera instead

You have to get android compatible sensors. Either the ugly looking external ones or the OEM looking internal ones. Ofcourse Teyes want you to buy their own one because they bundle that app in and their app only works with their sensors. But I already had internal sensors Deelife brand from before so wasn’t willing to change. I have the battery replaceable version of the Deelife internal sensors with enough service parts to last 50 years lol. By service parts I mean stems, gaskets, washers and screws. But if I was buying new then ofcourse probably makes more sense to get the Teyes sensors for a more seamless integration. Here are some pics of my TPMS

 

 

How did you manage to get them to work if the app only works with the teyes sensors?

I’m not using the Teyes TPMS app. I’ve disabled the built-in Teyes TPMS app and installed a customised Deelife app to look like Teyes UI. I much prefer the Deelife app. Someone I know got the Teyes TPMS sensors but the Teyes app isn’t as well refined as my modified one.

2011 Lexus IS250 Teyes CC3 2K - Volume Failure

I would greatly appreciate any feedback or advice on the following:

Install instructions I followed as as per:

https://www.teyes.com.au/pages/b-harness-lexus-is250-xe20-2005-2013-f1

https://drive.google.com/file/d/19Uw6Ah-NTFEXOR14YaVHbJ3IS5-euCgC/view

Hi all. I installed the Teyes on 29/06/2023 and the unit functioned perfectly for 8 months until suddenly, the PWR.VOL button stopped turning the car speakers on (and the respective vol icon ceased to appear on the screen). I've attempted to illustrate in the image attached.

I also note that the fascia buttons no longer make the beeping sound when pressed. Everything else seems to be functioning as it was before (albeit without sound) Steering wheel and fascia buttons activate the functions on the Teyes and Display.

* I also note another strange occurrence in the last couple days in that the a/c display on the teyes screen randomly appears and disappears from time to time without any buttons being pressed. 

Troubleshooting to date:

1. Factory restart

2. Disconnect car Battery

3. Checked all fuses

4. Replaced existing amp with 2nd hand factory pioneer amplifier

5. Pulled out unit and checked all connections

are your deelife sensors compatible with the stock system or do you have to deal with the dash lights being on due to not having compatible TPMS sensors? Do you have a link to the ones you use?

As far as Im aware UK IS250s dont normally support the factory TPMS system, only the IS250C supported the TPMS system so assuming the car is a UK non convertible and hasnt been modified nothing will appear on the dash. 

These TPMS systems will only work on the android head unit only; so whichever one you get will work as long as the corresponding app is used, if you buy a non teyes TPMS system youll just install the relevant APK to view the TPMS system
