[Android Head-Units] DreamMaker888:
Hello everyone, I have completed my CC3 2k install and wanted to share the obstacles I came across and how I corrected them. JBL sound system, steering wheel controls, rear view camera, bluetooth connectivity, TPMS, external mic ... all working. The only thing not working as yet but I think I have it figured out is to get the rear view camera always on ... I will explain later in this post. (Btw, I apologize for the length of this post)

I initially ordered my unit from Teyes Aliexpress as it was cheaper ... big mistake! I got all the accessories but the CC3 was rejected at the China customs before exiting and sent back to Teyes. Teyes wouldn't ship another one and simply said to put in a claim for a refund. I didn't get the whole amount back and lost on the shipping costs as well. Re-ordered the CC3 from Teyes Australia and received it within 2 weeks. In both cases Teyes sent wire harnesses where none of the connectors matched my OEM plugs. Neither China or Australia was able to hook me up with the proper harness so I had to do the digging myself. I found a suitable harness with Canbus made by Roadivox on the Russian Aliexpress but they cannot ship to Canada so I traced it back to the Chinese Aliexpress ... all the connections fit like a glove. This harness is presumably suited for:

Toyota Tundra 2nd generation (XK50;2007–present)

Toyota Sequoia 2nd generation (XK60;2007–present)

Lexus 330/350 3rd generation (AL10;2008–2015)

When I first hooked up the CC3 I had no sound whatsover. I wired the 2 blue wires on the harness together, I believe they were marked "CON" and "AMP" and I got sound. Next I shifted into reverse and I was surprised that the OEM camera worked but the picture was awfully grainy. Hooked up the Teyes Sony camera as per instructions and found that it wasn't being recognised, neither in reverse or activating it in the rear camera app. After a couple of days of troubleshooting I found that the OEM trigger wire was providing signal to the Canbus Decoder which in turn output a 6v DC supply through a brown wire going to my vehicle's cam plug. Hooking the OEM trigger wire directly to the CC3 would not work and connecting the rear camera red wire to G3 also did not work. I cut the brown wire from the Canbus Decoder that was providing the 6v feed to the vehicle harness and connected it to the RED wire coming from the rear camera and to my surprise again, the Teyes camera worked being only powered by 6v (image attached). With this setup the rear camera works only when I put the vehicle into reverse but not with the camera app.

When the weather warms up in the Spring I plan to utilize the yellow wire of the rear camera (it is presently hooked up to the reverse light in the rear but not connected to the CC3) and disconnect it from the reverse light and splice into the red wire at the camera. Then I connect the yellow wire at the CC3 to G3 in order to get 12v supply. I am hoping this will power up the camera for the app. My only concern is whether the 12v supplied through the yellow wire will back feed into the Canbus Decoder which supplies the 6v only in reverse. I am hoping that since the 6v is only present and triggered by the Canbus Decoder when in reverse that the 12v won't make it's way past that trigger point and fry the decoder. If anyone out there has any thoughts on this please share.

The OEM had 2 antenna plugs which I connected together for better radio reception. Links to the antenna adapters here:

I used the OEM GPS antenna instead of the Teyes provided one with this GPS adapter:

As for the external mic I used the Teyes one and disabled the internal mic. No issues with calls, sound quality or volume on either end of the phone line.

For wifi connectivity through bluetooth I used the Tasker app on my android phone.

I hope this info will be helpful to anyone in the group. Good luck.
