Idatalink will not not retain factory microphone with an aftermarket head unit.

Q
Will this allow me to use the factory back-up camera in my 2011 Tacoma? Now the camera displays in the rear-view mirror (tiny), and it would be much better if it rendered in the touch screen Kenwood stereo I want to get.
[ Chip  Nov 21, 2018 ]
4 answers
A
I was able to make the camera work in my touch screen stereo but I had to buy a camera wire, cut off the end, and splice in an RCA plug to the camera input on the back of the head unit, so it would plug into the input onto the head unit. It can be done but it's not a simple plug and play. Hope this helps, sorry I don't remember more I did it 2 years ago. Good luck
[ Susan  Dec 13, 2018 ]
A
you will also need the module to run your camera and other factory features. This is just the wiring harnesses for it. The module is sweet though, it will give you truck data that you dont even get with your factory readouts in the dash like tire pressure for each tire and all of the temperature sensors.
[ Robert  Nov 22, 2018 ]
A
Yes. I kept the Sienna camera in the original display (tiny) and added another camera that displays through the 7" screen. I could have just sent the original camera to the larger display.
[ tedpas  Nov 21, 2018 ]
A
I'm certain it is possible. But when I did this install in my 2012 Tacoma I didn't find the video cable anywhere in the dash harness. So I kept the factory rear view camera in the rear view. I did add a front facing camera though, and programmed one of my steering wheel buttons to activate the camera when pressed and held.
[ David Lee  Nov 21, 2018 ]
Q
I want to install this in my 2006 Toyota Sienna, but Crutchfield says that this harness will not fit in my vehicle. Is this true? The description says it's made for 2006 Toyota Sienna and up.

I see that the main harness plugs into the aftermarket stereo and has bare wires on the other end. Is there another adapter that accepts the bare wires so that it can plug into the factory radio harness? Is this harness included if so?
