Nexus 7 (2013) tablet install in the dash

I've pondered this install for over 2 years and finally decided to go ahead with the install.

I had originally upgraded the sound system in car by pulling out the stock Nakamichi Head Unit (a couple of years ago) and replaced all the wiring, speakers etc with decent components - Mid and tweeter (separates)- Focal speakers in the front door and a 13 inch Focal sub in the trunk. I focused this upgrade for an SQ setup and did not install any speakers in the rear on purpose. For amps, I used two Zapco's (one for the fronts and one for the subwoofer)

I installed a Pioneer AVIC-D1 navigation/Head Unit and also installed tons of sound deadening all over the doors, trunk etc.

Fast forward to today and here is my new setup - since I had upgraded the wiring and speakers already, I focused this build on the Tablet install and a new HU that connected to my upgraded wiring. I then connected the tablet via the USB DAC (the Microstreamer unit) to the Head Unit aux input for audio out to the car speakers/amps. This simplified my install as I only needed to focus on the tablet install and the new Head Unit Install. Needless to say I ripped out the Pioneer unit for this install.

I flashed Timur's kernel ( https://timur.mobi/timurs-kernel-n7-2013/ ) for a fixed install as its perfect for these types of installs - the tablet goes into a deep sleep mode when accessory power is shut off and it loses very little charge overnight (roughly about 1 - 2 % per 10 hours). As soon as you turn on the car, the tablet senses power has been applied and the screen comes on immediately. So even though my install allows me to remove the tablet from the car, I don't really have to remove it. It comes on immediately when the car is turned on and goes off (deep sleep) when the car is turned off. You don't need to setup any complicated (for me anyway) tasker routines to take care of this. I then connect my tablet to my Note 3's hot spot for Internet access.

I had the install done professionally - the custom fabrication of the tablet and Head Unit mount. That was really the main part of this install by Ultra Auto Sound in Mississauga, Ontario ( http://ultraautosound.com/tag/nexus/ ) . They did an excellent job as you can see from the pics on their website and below. Thanks Joe!

I haven't been able to get the backup camera to work yet with the tablet as my understanding of how it works with the tablet was not thorough enough and I need to do some more reading to figure it out properly.


Here are the parts I bought:
  1. Nexus 7 (2013) tablet ofcourse
  2. Head Unit - Kenwood eXcelon KDC-X998 CD Receiver with built in BT and HD radio - its one of the better Head Units on the market right now ( http://www.amazon.com/gp/product/B00...ilpage_o03_s00 )
  3. USB Hub - DLink 7 port USB hub ( http://www.amazon.ca/D-Link-DUB-H7BL...ink+7+port+USB )
  4. USB DAC - HRT microStreamer ( http://www.amazon.com/gp/product/B00...ilpage_o01_s00 )
  5. Backup Camera - TaoTronics TT-CC17 Waterproof Color CMOS Car Licence plate backup camera ( http://www.amazon.ca/TaoTronics-TT-C.../dp/B0092YMZJY )
  6. USB Video capture card - VGB100 USB 2.0 Video Capture Device card ( http://www.amazon.com/August-VGB100-...re+Device+card )
  7. Bluetooth remote for audio controls - SatechiĀ® Bluetooth Button ( http://www.amazon.ca/gp/product/B00R...ilpage_o04_s00 )
  8. USB Flash drive - SanDisk Extreme 64GB USB 3.0 Flash Drive ( http://www.amazon.ca/gp/product/B00K...ilpage_o02_s00 )
  9. Micro USB OTG cable and charger - (http://www.amazon.com/gp/product/B00...ilpage_o02_s00)
  10. USB 2.0 A-Male to A-Female extension cables for charging my Note 3 and my wifes Note 2 while in the car ( http://www.amazon.ca/gp/product/B00N...ilpage_o01_s00 )
  11. OBD2 BT dongle. This allows me to display a bunch of information on the Dash Command app (shown in a couple of pics below with the LFA "skin"). You can also read any error codes without paying an arm and a leg to the dealer.


Here is the before pic:

The install looks great. Good job. I've got a 2011 GMC Sierra that I've installed my Nexus 7 (2013) in the dash. Turns out that the double din after market head unit adapter plates opening is just a hair bigger than the actual LCD. ( not the whole tablet but just the LCD). So I was able to use it with the Nexus mounted to the back of the adapter plate so that it fits tight against it covering the edges of the tablet and only leaving the LCD exposed. I'll take some pics and upload them soon. Good job on yours. Love seeing how others went about their install.

nice built but may I ask, is it really needed to add an usb dac to the instalation process if I am runing audio from the tablet with 3.5mm audio jack cable to the car's player aux ?

Thanks. I love the setup as is and the audio shop that installed it recommended mine be setup (the mount) like this because of my requirement of wanting to be able to unplug it or get to the buttons for whatever reason. I personally prefer the look that you went for where the tablet is behind a plate as that looks more OEM than mine.

Mine looks so obviously like a tablet on the dash even though the quality of the audio shop's custom mount is good, it still doesn't look like an OEM screen (when its behind a plate).

My installer said it would be more expensive to mount it behind a custom opening and also make it removable at the same time, hence the end result you see here.

Looking forward to seeing pics of your setup!

No you don't have to do what I did especially if you are not pulling out your stock stereo.
