Nexus 7 Install
6 Attachment(s)
So i have wanted to do this for a long time on other vehicles but i didn't plan on keeping them so i put it off. I plan on keeping this truck till it falls apart so decided it was time to try it. I really wanted a NAV unit and i wanted to run torque all the time. This allows both and more. This is my first time doing a build Thread so i will probably leave some stuff out but i haven't seen any other Nexus installs so figured i would make one.

What i ordered

Nexus 7
"Sponsored" Timur's Kernel

Ford Wire harness
90 Degree OTG cable
USB Host OTG cable + Charging
Amp Kit
Double DIN install kit
5V DC regulater
I also purchaced a 12V relay, some extra wire and a fuse holder.
I had a USB to headset dac already handy so i did not buy one but probably will upgrade to a better one later.

I am still working on a fix for steering wheel controls and backup cam. i believe i have found a fix for those but as i don't have it working yet i will update later when it is.

First i cut/dremeled out a slot on both sides of the double din face plate

i then ensured the tablet would fit properly and be held securely by the frame.

I then ran the all the wiring. here is a diagram of what i installed. Forgive my skills in paint. its what i had :dunno:

And here is the final product.

The tablet, when configured with Timur's Kernel, powers up when it receives power and goes into a deep sleep when power is lost. The kernel allows USB host mode and charging at the same time. Host mode allows you to run usb accessories like HDDs, webcams, ect. I plan on rerunning the usb that is in the dash to the hub so i can easily load new music or pics via usb drive. Let me know if you have any questions and i will answer to the best of my ability.

Very nice! Subscribing.

I've got an Asus K01A. I'm guessing that Timur won't work with it? :dunno:

Most likely not. The kernals are usaly device specific.

I'm very interested in this project, and have little knowledge on how to accomplish it, so some of my questions may be dumb, but...

Why did you go with the 32 GB Nexus instead of the 16? Couldn't an external HD be connected through the USB port if needed? Why didn't you go with the LTE unit?

Mostly comes down to personal choice. I personally always want extra storage. USB drives should be good. The only thing you have to watch for as in my setup the hub loses power when I shut off the truck so the nexus may have to refind all the music. The kernal I'm running should fix that but I haven't messed with it yet.

I didn't go with LTE for cost reasons. The LTE version cost about 150 more in most cases. Also to use LTE you have to pay an additional access charge every month. I desided that I would just teather it from my phone instead. It gives it the same capability and if my phone doesn't have service neither would the tablet.

Hope that awnsers your questions.

I'm getting my order ready, and I'm looking at the90 degree OTG cable and the USB host OTG cable + Charging. I can't figure out how the charging cable plugs into the 90 degree cable. What am I'm missing?

if you get the 90 degree cable it needs to be a micro to micro. a normal otg will be mini to normal usb
this would be more like what you need
i will warn you that i had to sand down some of the plastic on the inside of the my dash plastic and still had a hard time to get a 90 degree to work. i had a problem today and am actualy taking off the plastic on the connection that plugs into the tablet so it will fit better

I appreciate all the tips! Once I get into it I'll be able to figure more of it out for myself.

Okay, I've got my tablet and have been familiarizing myself with it. I understand that the process of installing Timur's Kernel will void the warranty, so I want to exercise it for a bit while its "stock." While I was initializing it, it listed a bunch of updates, so now, among a lot of other things, I've got 5.0.2, which I now see that Timur says there is a beta for. I hope that isn't going to make things difficult...

BTW, SuchTrk, are you going to incorporate FM or satellite receivers into your installation for when you're out of wireless range?
