Thought that I would do a quick update and post up my parts list - which is almost entirely available on Amazon Prime. Definitely some trial and error in finding the right components and making it work. Below are the items that I used in my build.
I'm hoping to to finish up the next iteration on the mount in a week or two. Will post another update when I have info.
Thanks for all the great feedback - would love to hear more!

Yup, I'm currently in San Francisco and have constant fears of people breaking into my van. The tablet is removable via a friction fit using some felt pads. The last picture in my post shows what it looks like removed (so you can also access the SD card). I plan to add another panel that hides the top section.

Looking forward to the full write up!
Thanks so much! Definitely hope to do a 4WD conversion in the future. May have to settle with Bilstein HDs and some stiffer front springs in the meantime.

What kind of back up camera do you use ? I tried an IP camera, but the delay is about 1-2 seconds which makes it unusable for a moving vehicle.
That looks great! I used a fairly cheap backup camera that has RCA output. Finding an Android compatible Analog -> Digital USB capture card is proving to be the challenge right now (most only work on Windows). I ordered one on Amazon 3 weeks ago, and it has yet to arrive. Will let you know when I get it all hooked up.

Most iPhone or Android phones are able to ‘Personal Hotspot’ and charge via the USB hub (depending on your plan). This shares the data connection with the Nexus 7 with the custom software. Basically, you should buy the cheapest model you can.
Prices as of 03/04/2015 on Amazon for Nexus 7
$175 - 2013, Wi-Fi 16GB (For the 2013 model, the custom software license is $30)
$110 - 2012, Wi-Fi 16GB, Refurbished (For 2012 - custom software is free - PM me and I can set you up with it)
Craigslist and you can find them under $100.
Let me know if you want help with the software installs - I'm creating another write-up for that.
USB Peripherals & Power
90 Degree USB Cable
- Not all 90 degree USB cables are built the same. Cheaper cables will charge, but won't work with your USB hub.
USB OTG Charging Cable
- Note that this is 2 cables - but the second one comes in handy when you take the tablet out.
Anker 24W 2-port USB car charger
- Soldered 18 gauge wire directly to power supply. Then hooked up via molex connector to the radio wiring harness. My next version will ditch the relay and you only need 2 wires - ground and ignition ‘on’ power.
Anker 4-port USB hub
- Purchased this Anker 4-port hub, but the cable quickly frayed, and I’m already out of USB ports.
* My next iteration will include this hub, which will require some additional wiring Anker 7-Port Powered USB Hub
Behringer USB Audio Interface
- This unit had great reviews from the other Nexus 7 reviews we found. Uses RCA to output audio, so it will wire up easily to any equalizer / amplifier.
Vehicle Specific Parts
Ford Radio Wiring Harness
Ford Double DIN Install Brackets
Ford Radio Removal Kit
BAFX OBD2 Bluetooth Scan Tool
or ScanTool OBDLink LX
- Once again, you have quite a few options here. The BAFX tool works OK, while the ScanTool is the best product in it's category (3x data transmission rate = smoother gauges. The data stream is also encrypted if you're worried about that type of stuff.)
Transcend USB SD Card Reader
- Works great
16-64GB SD Card of your choice
- If you want to transfer files from a PC - format as NTFS. If you want to transfer files from a mac - format as FAT32 (limitation is that you can’t have files over 4GB)
Esky Backup Camera
- For $20.99, this had the added surprise of arriving with 2 cameras, which is cool. We used the ‘no guidelines’ version since it will be installed on the roof. This backup camera has an analog video out, you will need an analog to digital USB video capture (see below). Plan to wire this up the reverse lights, with a manual override on the dash. Also gives the advantage of being able to get some light up the area when its dark.
Android-compatible video capture card
- I purchased a cheaper ‘EzCap’ style video capture device for $15 on Amazon, but it turned out to be not compatible. You may be able to find a cheaper USB capture device, but make sure it is ‘linux compatible’ and doesn’t need any drivers. The cheaper devices use a low cost controller over a USB keyboard interface with propriety drivers that doesn’t work on Android, which requires a 'UVC' or webcam style interface. Still waiting to receive this item.
