Hey guys/gals,

Thought i would share my most recent project with you all in the hopes of getting some advice and feedback and showing off my install

This will be an incremental build thread, i'll add to it as i get more pics and work my way through some issues.

I have installed a Google/Asus nexus 7 in the dash of my MY00 Subaru WRX. I trialled the optus mytab (AKA ZTE V9) in the dash but it didn't last more than a day since it was a piece of crap performance and audio-wise.

After spending a few months building a nano-itx double din touch screen pc to go in the dash, i changed my mind (for the millionth time) and decided to stick an android in there instead. The intel PC is now sitting in a box at home doing nothing...

The biggest trouble was finding a tablet that would fit in below the A/C controls nicely.. in the end, the N7 was about 3mm too big bit i broke out the dremel and made it fit!

Having trouble with the audio output though, it is horrible... it buzzes every time i touch the screen and it buzzes when wifi is active and it is just generally crap.

I would like to plug in a USB soundcard (DAC), something like the Fiio E10 but then i wouldn't be able to charge the tab while USB OTG is active.

I was hoping that the pogo pins on the side would allow charging whilst the USB dock connector could be used for OTG but it doesn't look like it will work since both the pogo pins and USB connector go to the same usb switch internally.

another edit: there seems to be a thread on the charging issues... i have also just found that my tab drains it's battery faster than it can charge it... I'll have to look into this further: http://forum.xda-developers.com/show....php?t=1791717

Parts list:
ASUS Google Nexus 7
4 Channel Nakimichi Amplifier
Single Channel Class-D 1000W Nakimichi Subwoofer amplifier
Four-Gauge power/ground
Gold plated Ground splitter and +12v Splitter/Circuit Breaker
Oxygen-Free Copper speaker cables (around 12 gauge)
(coming soon) 1.5 Farad Capacitor (to stop headlights dimming)
2 x Kenwood 1200W Subwoofers
4 x Focal 6" Splits
Good quality RCA cables
R/A 3.5mm headphone plug to 2x RCA 30cm cable
R/A Micro USB cable
gutted tomtom GPS charger
(coming soon) RCA volume level control (thanks for the idea ahavens17)
20mm wide metal strips
Hook and Loop velcro
Rubber trimming/edging

Update: Added some more pics showing my crude but effective way of holding the tablet in-place.




To hold the tablet in place, i have used some metal straps cut to size that are screwed on using the screws that hold the top of the ash tray to the dash fascia. I stuck some velcro on to the metal straps and 2 small strips on the back of the tablet to dampen vibration and stop the tablet sliding around sideways. The velcro also stops the metal straps from marking the back of the tablet (not that it matters since it is hidden behind the dash)

You can see how it is done in the pictures above. Also, I am using right-angle micro USB and audio connectors so that they fit nicely in the dash

My blog of the install is here: Finniss.net
you may or may not find more updated info there as time goes on.

I'm not talented enough to do this to my car. I just have to lay my tablet on the passenger seat.

I'm not that talented either but will just end up using a dremel and some Velcro or something lol

I have a huge double din slot so I won't have to do much cutting at all I will have to buy a cheap 40$ radio to put where my 6 disc CD changer in so I an use that as my AUX input as I am not buying an amp using stock speakers plus I would like to use FM just for sometimes you know lol and possible CDs

Now what would be super cool is to have your tablet start your car when you NFC bump it! Someone work on it!

Heh yeah, mine has a brandt alarm system on it with a keypad which may pose a challenge but not something that i am totally unfamiliar with ;P

p.s. that sounds dodgy... I have spent many hours messing with that stupid alarm system to avoid having to tow the car back to subaru head office when the alarm system dies (which it frequently does, requiring replacement)

Looks like he is using a bluetooth -> OBDII engine diagnostics cable and the android car home app. I've toyed with this before too and it's setup on my Nexus 7 now
