Tacoma - Entune replace w Nexus 7 - camera/controls mod

[wi11iamedward]

I want to install a Nexus 7 into my dash to replace the stock Entune system, mainly to save money on annual service costs. But also just because I loath the Entune system as a whole.

I have found local companies that will do the dash mod but no one has offered a solution that would get my backup camera and steering wheel audio controls to work with the N7 unit. I don't want extra wires or controls hanging about, and I do want to reuse buttons if I possibly can.

There would be 8 buttons available for programming/rewiring to control things with the N7 unit. And there is a backup camera located in the tailgate that I need to make work before I can make the full conversion. Currently, the Entune system will display the camera on screen when the vehicle is in reverse; I would much rather this be on demand by opening an app than trying to rebuild functionality like Entune forces.

Thoughts?

Are you having a software or hardware interfacing issue?

Both really. I'm not sure what software is needed to make the backup camera work. And I'm not sure what hardware modifications are needed to allow the N7 dock pick up and interface as needed.

I've updated the original post to give a bit more detail.

there are a few ways to do it. One is to use all external devices and not touch the insides of the Nexus. You can also remove the back cover and do some wiring to the necessary components. I suppose it depends on the direction you want to go. Here is a site reference about a similar project and some solutions. My personal opinion is that replacing the rear cam to a wifi cam with a wifi camera app may be the simplest, less intrusive way.

This one suggests a hardware extension cable from inside

Here are some apps you could try if you wanted to go with an IP cam on the rear.

That's great information to go through. I believe the option I want to aim at will be a wireless option. If that's true then I'd need to find a IPcam that would either fit in the current camera's housing (preferred) or fit elsewhere on the vehicle, like the trailer hitch.

All of the rest of the install looks fairly straight forward.

Addendum:

1. Can you modify a camera unit (in this case a Toyota backup camera) with an arduino setup so it can be used as an IP camera?

I think I might have found a solution for the camera... however I can't seem to find a release date for it yet.

I'm still looking for anyone that can help finalize this solution.

Can anyone direct me in a way to modify a backup camera (camera only) so that it can connect to a USB connection? Or Cat5?

Here's where I'm going with this... Nexus 7 -> miniUSB -> Cat5 -> USB -> Camera I thought this might be capable of carrying the power and signal for the length I need it. And I have seen others who have gotten USB webcams to work with the Nexus 7/miniUSB/Cat5 conversions, but I need to mod my existing backup camera to interface with this.

Thoughts?

I am not sure you ever stated what your existing camera uses, most of what I have seen (not much) is 12v and composite signal, you cant interface it without knowing what it is, and nor can we really help.

Thats easy enough to alleviate.

This is he same camera and connection view in my tailgate. The only difference is that in the headunit it connects to the Entune system, not the rear idea mirror.

Thanks and let me know if I can clarify anything more.
