Someone can jump in and correct me but I don't believe the stock camera is 12v so the teyes camera will require a new wire. It might have actually been discussed in this thread.
I just did this. Taped 3 wires (two for the RCA and one for the trigger) and it works no problem. Obviously picture quality is off the early 2000 era but you’re nor watching a movie with that camera. Is enough to see where you’re backing up on
No I meant using the original cable with a new camera and the Teyes CC3 unit. I can't think of a reason why the old camera cable wouldn't work with a new camera. But then I haven't had a look at it yet.
I think the original camera was 6V and I don't know whether that was fed from the head unit or not. But the cable doesn't care if it is 6V or 12V. I'm talking about just using the existing cable with the Teyes at one end and the new camera at the other. You might have to add a connector or two at each end, but it would save all the effort of routing a new cable.
Thanks. I'll take a look at this and figure out how they are doing it. It's an analogue circuit after all - so should be pretty straightforward. The Yellow wire is simply powering the camera when the wagon is in reverse. I've done plenty of wiring but why run a new cable when you can use the original one? Especially when you don't need the original camera any more.
I've just prepared detailed instructions on how to fit the CC3 2K head unit and an Aycetry AHD rear view camera (1920x1080) to a 2005 Lexus 470 (stock audio system - Pioneer). I intend to reuse the stock camera wiring, rather than running a new cable. The instructions have been generated using AI (Gemini) based on a rigorous search of the internet. Only problem is, I don't have the headset yet and so haven't actually done the job yet
. I can test it out and share once I've done the job successfully 
.Interested in seeing this. I tapped into my rear view camera module and if i can replace the factory camera with an aftermarket one and use the existing wires would be niceI've just prepared detailed instructions on how to fit the CC3 2K head unit and an Aycetry AHD rear view camera (1920x1080) to a 2005 Lexus 470 (stock audio system - Pioneer).

)) and he tells me that this particular LX 470 model uses analog signals for the steering wheel controls, rather than digital. Obviously, the AC is digital and is working (pretty) well. Gemini advises cutting the factory audio harness wires and connecting the analog lines from the steering wheel to the Teyes analog Key 1 and Key 2 inputs. And then to go through the process of teaching the Teyes unit the steering wheel buttons one-by-one. Has anyone had to do something similar? It seems that the ML LX470 variant uses digital steering wheel button/signals rather than analog Does this sound right? Has anybody needed to do this to get the SW buttons working? Or is Gemini smoking weed 
I'm looking at this at the moment. After a bit of experimentation, I found that the Blue "Ant" line out of the Teyes CC3 2K (in my case) has voltage on it all the time - even when the car is completely off. So I can't see how you can use this to control the antenna. There is a switch in the Factory Settings that says "Antenna Normally On" but toggling this on and off doesn't make any difference. I don't have a rear radio, so can't use this to power on the antenna. It's always down. I'm working on a solution using a new switch on the centre console to power the antenna on and off. But surely that Blue wire must do something? I've asked Teyes technical support to see if they have any insights.
On the subject of getting the antenna to work properly with the Teyes install, I've got a bit further and I've found the mythical second radio. To activate the antenna, I press the FM or AM button on the old cassette/radio front panel (which is left in place when the Teyes is installed) and lo and behold the antenna goes up and a new radio app pops up on the Teyes screen. Only problem is - there is no audio on the new radio app. When I go back and run the normal radio app, the antenna goes down but I have sound in FM mode! What I think is happening, is that the FM/AM buttons on the old tape/radio front panel (in my case) - or turning the rear radio on (on LX 470 ML models I think) makes the car electronics send a signal to the Teyes unit to say that the radio has been selected. This signal arrives on the antenna wire of the main 20-pin Lexus/Toyota audio connector - (R37 pin 13 in my case) . This causes the Teyes unit to launch the 2nd radio app.
Hi. I'm working through this as well with my 2005 LX470. Mine is a RHD NZ/Australian model and so doesn't have the Mark Levinson audio system that US models have. Mine has a Pioneer amp. They have different wiring. In fact, mine seems to have some of the 2002 version wiring.
. Haven't fitted these yet.
I managed to sort this out. If anyone else has this problem - the app is Cam REC. When I ran this app, it said "this is a paid service please contact your reseller" (or words to that effect). But If I long pressed on something in the app (can't remember what it was), it started displaying the rear view camera, and it still does. I presume they were/are planning to pay extra for live view - but it works nonetheless.
I would recommend buying new ones. The slee kit comes with new grommets. If you are really careful you can get them out and reuse, but the metal is very thin in that area. Easiest way is to remove is drill out the old ones.
