Nexus 7 Install on a budget :-) (BL Legacy)

Recommended Posts

So I decided I liked the idea of the Nexus 7 in dash, but I was not that keen to splurge the $500 plus on plastic parts from Japan in the form of the facia kit and info display relocation kit, so I came up with a bit of an alternative. For 2 reasons. One being the cost of the parts the other being the fact that I actually still like using my tablet and didn't want it dedicated to the car

Here is the list of things I purchased for the build

1 x Nexus 7 2013 (WiFi) NZ$122 (Second hand off Trademe)

Purchased Timur's Kernel for power management.https://timur.mobi/timurs-kernel-n7-2013/ $35

1 x 12v DC to 5v DC converter 4 port USB power (5A total)http://www.ebay.com.au/itm/321530483883 $12

1 x OTG Y Cable http://www.ebay.com/itm/251620434151 I like the 90 degree connector $3

1 x Hard case for the Tablet http://www.dx.com/p/protective-abs-back-case-for-google-nexus-7-ii-black-247238 $6

1 x Video Grabber for reversing camera http://www.aliexpress.com/item/Factory-price-EasyCAP-USB2-0-Video-Adapter-with-Audio-1channel-and-2-chips-STK1160-GM7113-High/1760001577.html $11

1 x Reversing camera http://www.dx.com/p/wired-170-degrees-waterproof-car-rearview-camera-for-subaru-forester-outback-impreza-legacy-194056#.VblRB_lhKBp $20 I will replace this at some point because the resolution is crap

1x Belkin HD Bluetooth receiver http://www.amazon.com/Belkin-SongStream-Bluetooth-Music-Receiver/dp/B00AG6NSNO $50 (I had Amazon credit so this was free for me) pluged into the aux port on the Anycarlink

1x Relay that I had lying around in the garage for triggering the reversing camera app

Total cost, $259 if you include the cost of the BT receiver

Things already in the car

1 x Anycarlink that connects to my phone for bluetooth

The big question was how to mount the thing. I looked the magnetic holders and tablet window mounts and all sorts of stuff like that but didn't really like the look of those. I wanted something that looked a bit more integrated. So I have chosen...... A block of wood.

Here it is my high tech dash mount in it's raw state.

I cut this from a normal bit of bearer and it slots perfectly into the dash cubby with the lid open. Nice and snug

Next I attached the case to the wood using screws and then I put the tablet into the case and slid it into the slot. Hey presto.

And just the home screen with the most used apps

I have painted the wood black too so it looks a bit better.

Just a few picks of the ghetto install. Sorry they are blurry.

I used a hole saw to cut out a part of the wooden block so I could fit the power supply into it. It is currently powering only the tablet's OTG and the Belkin BT receiver

Different size hole saw to cut out some space at the back of the cubby.

This is the video grabber. I know it isn't pretty but it lives hidden from any sight. I have split the 5V+ on the USB cable and put that through a relay which is triggered by the reverse light, so the video grabber only turns on when I am in reverse. This in turn triggers the vCam application on Timur's Kernel so the reverse camera turns on automatically. Very clever TImur. Using option 1 from here https://timur.mobi/timurs-kernel-n7-2013/auto-rearcam/

The Anycar link is connected to my phone for mobile calls and the Belkin unit is connected via 3.5mm jack into the Anycar Link. I tried a few cables to get decent sound quality and settled on a Belkin cable.

The Anycar links into the CD changer port on the McIntosh system so I can pick up calls from the steering controls.

Last but not least. I have this mobile wifi unit for data to the tablet. I got this because tethering to my phone used the phone battery and it's bad enough as it is.

Tablet talk installed so I can make and answer calls from the tablet directly.

Awesome, for anyone running an android tablet in their Subaru, I've gotta recommend the app BTSSM (you'll need a $10 USB vagcom cable to connect to your OBDII port). It's fantastic for monitoring/logging/gauges.

http://www.btssm.com/

If you look at the pic of my home screen you will see that I have BTSSM on there already. I run it through my Tactrix openport 2.0.

I'd like to do something similar, but still retain vision of the clock/fuel info etc. Do you think you'd be able to mount the case higher up to do so? I've got an anyCar link too, but the BT audio isn't super great, so I'd consider just using a 3.5mm audio jack to the anycar. Can you elaborate more about the Reverse Cam and relay setup. I've got a 2012 Nexus 7 would that work?

There is a clock relocation panel you can get to relocate it to where the ciggy lighter sits below the A/C. Works for the permanent setups but will leave a gap up there if you're thinking about doing it like mcdoof and having it removable.

That's cool ^

OK so stupid question that's probably been covered numerous times else where. I have an 06 JDM STI which connector things can I use/which one is best value for $? Just not sure if it's can, or K line or whatever :)

You mean those kind of connectors? Subaru to iso ones for connecting new HU's?

Don't bother with them myself, always just hack the one that comes with the HU into the stock wiring.

Not sure why CAN would come into the stereo side of it. Unless the clock is connected to it to source the fuel data maybe

Oh, I was meaning a connector for the ecu etc to run something like that btssm thing or the torque apps. Like the tactrix thing, never looked into it until now :S

Just noticed this is in I.C.E haha oh well

I guess you could mount it higher so you could still see the clock. I just have the tablet set to daydream so it's always a big clock. The fuel data was never really accurate anyhow. The camera trigger I used is option 1 from here https://timur.mobi/timurs-kernel-n7-2013/auto-rearcam/

I had the relay in the garage already so that was lucky.

Pity the BT audio on your anycar link is bad. Mine is better than the CD player. Phone calls are a bit soft but music is very good.

Perfect. Thanks! I want to do a permanent install, so that relocation kit would be ideal. Do you know if the nexus 7 2012 will work with the reverse cam etc, or just 2013? My AnyCar has BT, Aux and iPod input, so I must stick to BT/Aux input as the USB audio on Android can be a bit finicky as I've found in the past (doubt It would play audio/charge with adapters off the 15pin male connection off the AnyCar link.

There are some roms for the 2012 Nexus but they are Android 4.4 AFAIK. I'm also not 100% sure which video grabber you would need on the 2012, I think it's a different unit.
