Nexus 7 Android Tablet into SG9 OEM Dash Pod

Here is a how to write up for the Nexus 7 that I modded into the dash top pod of my SG9 Forester.

While I was doing this mod to my car, I found very little documentation and since installing the tablet I have had quite a few people ask me how I did it.

I have been running this in my car for around 5 months now with no real issues (the only possible problem is that it can turn itself off if you park the car in direct sunlight on +35c days, I solved this issue by getting a sun shade - a good idea anyway if you are parking your car in the sun).

This mod may differ slightly for USDM models.

IF YOU DO THIS MOD, IT IS AT YOUR OWN RISK I DO NOT HOLD RESPONSIBILITY FOR ANY DAMAGE DONE TO YOUR CAR OR YOURSELF AS A RESULT OF FOLLOWING THIS DIY

Here is the finished product!





Tools Required:

1) Trim Removal Tools
2) Phillips Head Screwdriver
3) Soldering Iron (or Crimping Tool)
4) Side Cutters
5) Power Drill

Parts Needed:

1) Subaru OEM Double Din Gauge Pod Housing:

2) Asus Nexus 7 (2012 version)

3) 2.1amp Car Charger (I used this one because it was the one that allowed the phone to charge at its full rate)

4) In-Line Cigarette Lighter Socket

5) Belkin Mix-It Flat Aux Cable (I used this cable because it allows the aux cable to fit without fouling the dash pod housing)
MIXIT? Aux Cable

6) Mini USB ELM327 Bluetooth Adaptor (You need this if you want to run Torque Pro, I chose the mini adapter because it sits in the OBDII socket flush with the dash, so you can't see it or bump it with your knee whilst you are driving). Similar to in this Link.

7) Aftermarket Head Deck with Rear Aux or Bluetooth Audio inputs (this is an optional extra for if you want to play music. I like to use Spotify on my tablet). I am using a JVC KDR-90BT Single Din Head unit.

8) Matte Finish (Anti-Glare) Screen Protector (This will make the tablet look more OEM when the car is off, it also will make it easier to read in sunlight).

9) Hardshell Case (any will do, even this tacky napoleon case)
http://www.ebay.com.au/itm/Napoleon-Bonaparte-Hardshell-Case-for-Google-Nexus-7-/231014926220

Software Needed

1) Torque Pro for Android
https://play.google.com/store/apps/details?id=org.prowl.torque

2) Torque Theme Pack (You want this so that you can change the colour of your torque dials to match the rest of the dash so that it isn't distracting when you drive
https://play.google.com/store/apps/details?id=com.rey.torquethemes3

3) Condi (You want this so that you can put the tablet into a low power state when the car is turned on or off. It also allows you to set brightness settings for nightime driving and turn on apps (like Torque pro) when the car is started.
https://play.google.com/store/apps/details?id=il.co.kix.minitasker

4) AutoSleeper (This is an app designed for Tablet in car uses. This is the key to making the car install work, putting the tablet to sleep/waking it up when the 12v power is turned off/on)
https://play.google.com/store/apps/details?id=com.as.powerchecker

5) Sygic (This is by far the best Navigation app that I have found. It is good because it works offline and includes speed cameras and red light cameras and comes with free map updates. The only problem with it is that it is expensive. Try it out first, it comes with a free trial)
https://play.google.com/store/apps/details?id=com.sygic.aura

6) Fullscreen (This app lets you change the GUI so that it doesn't obviously look like an android device in your dash. This means more screen real estate for gauges and it makes it look more like an OEM satnav unit. Maybe I am just OCD)
https://play.google.com/store/apps/details?id=de.tsorn.FullScreen

The Install

Step 1: Remove Dashtop Storage Cubby
If you pull this cubby forward, it should just come out (There are no screws for this section, it may just need a little force to come out). Once the pod is our, unplug the clock and put the cubby aside.

Step 2: Remove Lower Section of Centre Console (this video will show how to do this really well):

Step 3: Install all of the mounting hardware for the dash pod.
To do this step, follow the instructions provided with the dash pod)

Step 4: Create the Nexus 7 Mount

Drill a few holes in the back of the Nexus 7 Hardshell adaptor, and cable tie the case to the clock adaptor provided with the dash pod.



Align the bottom of the dash pod with the bottom corners of the tablet.



You may need to drill new screw holes to get the alignment perfect.

Step 5: Creating Additional Power for the Tablet



Remove the plugs connected to the back of the Cigarette Lighter plug. Once this loom is disconnected from the car, solder (or crimp) a wire in line with the red wire (+) and the black wire (-) and connect these wires to the positive and negative of the additional cigarette lighter plug you have purchased. If soldering make sure you use electrical tape/heatshrink to protect the connection from shorting out on anything. (NOTE: FROM MODEL TO MODEL, THESE COLOURS MAY BE DIFFERENT - CHECK BEFORE YOU CUT OR SOLDER).

Once this step is completed, plug the USB charger into the new Cigarette lighter plug, reconnect all cables and check the charger is working correctly.

Step 6: Running wires to the tablet

Tape both the MicroUSB cable and the AUX cable to the end of a coathanger and feed it up the left hand side of the centre console. There should be a clear run up this side of the dash. Connect these cables to the tablet (the respective plugs).

Step 7: Test Connections and Put lower console back together.

Test that the power to the tablet and the AUX cable is working correctly. If this is all good. Put the lower centre console back together.

Step 8: The Software

Install Autosleeper (link at beginning of thread) to the tablet. This will allow the tablet to turn on and off with the car. Set the timer on the app around 3-5 seconds (this will give you enough time to keep the tablet on when the car is turned off).

Install Torque Pro - While you are doing this, plug the ELM327 Bluetooth adaptor into the OBD port (below the steering wheel).

Install Condi - In this app create the following macro.

(12v off) - Turn on airplane mode, turn off bluetooth, close torque pro.
(12v on) - Turn off airplane mode, turn on bluetooth, open torque pro.

Step 9: Put cover on dash pod.

Pretty self explanatory. The first time you put it on, it may require a little bit of force to put it on.

Step 10: Enjoy your car with it's Snazzy new Tablet Install!

Great job Maaark!

As I type this on my Nexus 7- which I've been using in my Forester diesel since 2014 (see here)- although I'm not going to install one permanently in my vehicle you've show me a thing or two- had been wondering about the best navigation program- like you I want offline. Plus the other utilities for brightness, etc. Thanks!

One thing I might say is, if you can, perhaps use a name brand to ensure that you're really getting 2.1A. Belkin or even Apple/Samsung/etc. Also I have found those 'cigarette lighter' sockets (have some myself) are slightly wider than a real cigarette lighter plug, plus they are a bit slippery on the side and the spring load on the +ve connection pin can push the item out of connection with the general car vibrations. This happens even when I've sanded the inside sides of the socket.

Can someone please explain exactly how to set up Condi correctly step by step..?
I did this complete install and it is perfect and want to share the write up details and photos - BUT > my tablet is dead every time I go to drive my Forester.
I do not understand how to use and operate Condi and I'm sure that's my problem :(
Please HELP ! Thank you...

Thank you for this post. Followed your instructions but also rooted and installed Cyanogenmod OS 12.1 and Open Gapps "pico" variant of the Google apps/Play Store. Running for about 8 months only crashed about 3 times while running Tom Tom Nav. AutoSleeper and torque pro run great. One of my favorite Mods.

Currently running this...

Great writeup. I have been running this for approx. 4 years, but I am getting the itch to change it up.

Lately, it seems to lag a little bit. I've noticed that youtube and Pandora sometimes freeze up...Pandora especially. I have also recently run into an issue where the screen forgets to go to sleep when I turn off the car, so the battery is regularly drained. Have you run into any problems? I would like to know how others running this setup have been fairing with it.

Thanks,

Brian

Brian, have you ever rebooted your unit since installation to see if it helps? I know once you install the tablet there is not access to the power button to do so. To fix this I installed Quick Reboot [Root] from the Play Store. From my help desk days, sometimes a simple reboot will remedy situations as the one you mention. What about updating YouTube and Pandora from the Play Store? My tablet is running the PureNexus root and there is an option for it to sleep after power is not detected. Other than that, I haven't run into any problems. I've had it installed for about a week and haven't had any problems with it as of yet. If you have any other questions, feel free to PM me. I'm actually in NJ as well so if maybe one day you'd like to see it in person, you are welcome to as well. JT

Yep...I also have Quick Reboot and I have update Youtube and Pandora. I was actually a little worried that updating them might have caused the lag. I have Powerdown installed on it, but noticed some funny behavior with it. I don't drive my Forester everyday, so the charging on the tablet is sporadic. One thing that I've noticed is that the low battery warning takes precedent over the Powerdown function, so if the battery is under 12 or 15 percent, when the Nexus loses power, the default modal window prevents shut down. Last night I turned off the ignition and got the Nexus warning, I dismissed the warning and Powerdown still didn't kick in. I turned the car back on, hit quick reboot, and made sure that all processes were reset. I turned off the car again and got the modal window, with Powerdown again failing to kick in. I quick reboot again, waited 2 minutes, turned ignition off, no Nexus warning for low battery and Powerdown kicked in, shutting off the device. BUT.....

An hour later, I was attempting to listen to Pandora and it was non-stop buffering. My hotspot connectivity was at full bars and my wifi signal was strong, I just couldn't get through a song without it chopping up. This wasn't happening 2 months ago, the Youtube and Pandora failures are pretty recent.

I see you are in Montclair...I could stop up there at some point...my in-laws are in Cedar Grove.

Hey mate this is an awesome build, I plan to do something similar. Im in Aus too and considering either using the same Pod you used or the JDM version which is a bit more expensive. I hear the JDM one is mounted a bit closer so its more in reach of your fingertips. With this one you are using do you have to lean forward much? I saw you used a Nexus 7, if you had used a typical double din head unit would that mean you wouldnt have had to do the USB stuff etc and some of the other mods? cheers

Excellent write up!! I'm new to Forester forums, thinking of doing this in my SG5 2002. It came with Stock double din dash pod with clock and navigation installed in it from Japan. I have been looking for a Nexus 7 2012 not sure if i can find one. Would a 2013 Nexus 7 do the trick? Also it is OBD 2 so im thinking this should work perfectly! What do you think??!! Thank you

apologies for reviving and old thread but i'm planning on doing this mod or something similar.
i have the dash pod on it's way so i'm currently at the research stage.
i'll probably try and get hold of the 2nd gen nexus (2013) assuming it has similar dimensions as the 1st gen?
has anyone running a nexus had any issues with leaving the battery in the unit? i'm a bit wary about having a dash mounted lithium battery left in the car on hot days... i found a thread on xda about running the tablet direct without a battery so might do a no battery mod
i'm planning on using macrodroid to autorun apps / switch power modes etc.

the tablet is going to be mostly used as a navigation screen, although i'll probably save some music to the tablet as well and connect via bluetooth to my pioneer head unit.

Which dash pod US or JDM? I believe the dimensions are different.

I’ve beat the hell outta my n7 2013 battery for the past 3 years and it’s still working fine. I run timur and it sits pretty for 3-4 days at a time with ~12% battery usage. The important thing is getting a quality cable that pushes enough juice, and avoid damaging the usb connector (or take a needle nose to it if it gets beat up). 100+ F Colorado summers and 5 F Michigan winters and only the occasional extreme weather stutters.

i'm planning on using macrodroid to autorun apps / switch power modes etc.
Never heard of it but timur kernel is the typical route. Flashing a bloat free opengapps, xposed and a force landscape app nets me just under 1gb free ram at idle.

the tablet is going to be mostly used as a navigation screen, although i'll probably save some music to the tablet as well and connect via bluetooth to my pioneer head unit.
The gyro and gps both work well for me, and offline gmaps has been fine. I find I’d rather queue up maps on my phone before I head out but that’s personal preference. I run yt music via bt to my pioneer hu, works alright but the 80prs only saves 2 bt devices..which sucks when friends ride along (1 is tablet 2 is my phone). I’d like to get usb audio running properly soon, it’ll only sound better.
If you buy a bt obdII adapter you can run torque for coolant temps and codes etc.

Good luck and hope this helps.

Considering 3D printing these double-din mounts in Carbon Fiber if I can get a good quality scan of mine. Just tired of searching for discontinued parts!!

The original is simply compression formed ABS like most car parts. Yes, ABS resists heat fairly well, but PC (polycarbonate) with Carbon Fibers within the material has almost twice the heat resistance. In terms of rigidity they are of similar profiles at that thickness, but again with PC-CF coming out in the lead.

In terms of 3D scanning, I have previously used photogrammetry but my friend has access to a laser scanner that should ensure proper dimensionality without a lot of trial and error.

This isn't a business or anything...it's just one of my hobbies. I routinely print parts for both my Foresters as well as my Corvette. Since I saw the mod using that double din piece on the SG (never new it existed...) and taking into account the difficulty I had in searching for and procuring one...figured why not.

Hope that answers your questions!

I don't mind paying for another one if mine breaks from taking it off too many times, but the shipping is horrendous... But the ability to modify it while looking "factory would be great. The slope towards the front makes it a pain to fit over sized head unit "floating" displays, while the opening is just shy of 2DIN, further limiting options.

Oh...I wouldn't charge forum members for them if it works out. Just ask that if you want it custom you pay for the filament used and obviously the shipping would be on you. I would simply release the design on open-source repositories if I weren't afraid of the legal implications.

I am sure there are, but I am by no means a master. I either deal with the printed texture or paint it and use a sponge to texture the paint itself lol

If I were trying to make a business out of it or something, it would be a different story. I'm just trying to make sure everyone doesn't need to spend $200 on Ebay for a part that probably cost $5 in ABS to make originally.
