    Discovery 1 in dash Nexus 7

    Well here we go, I have finally gotten started on my in dash tablet install.

    I have decided to replace the head unit in my 96 Disco 1 with a tablet in order to gain some extra functionality from the slightly outdated interior.

    I chose to use the Nexus 7 as it runs android, an operating system I am comfortable with, and is quite regularly installed in vehicles overseas resulting in a number of ROMs that will allow me to run sound out via USB, connect a large storage drive and even connect a reversing camera down the track.

    I am permanently mounting my Nexus 7 and so, to drive the speakers I am installing a 4 channel amp under the passengers seat.

    The tablet will deal with music, navigation both on and offroad, and movies (for when the car is stationary of course)

    The tablet will be connected like this.



    The tablet will turn the display on and off automatically with the application of power, allowing it to operate like a traditional head unit.

    When the ignition is turned off the tablet will turn off the display, wait 5 mins and then turn off any unnecessary functions, shut down all apps and enter a deep sleep mode.
    The battery should last a few weeks in this 'sleep' state and be ready to start up when the car is next started.

    I will have an extra port on the Hub extended to somewhere on the dashboard so I can connect a flash drive or hard drive.

    I will do my best to update this thread as I work my way through the install.

    Step 1 - Dash modification

    I purchased a second dashboard to allow me to complete my modifications while still having a usable car.

    First I had to widen the opening where the head unit sits with the Dremel and a cutting disk so that it would be wide enough for the tablet.



    Once widened I test fitted.
    That is about where i hope the tablet will sit one it's installed.



    Unfortunately I missed a couple of steps here but I cut a piece of 1mm ABS into a bezel for the tablet and glued it into the space with superglue.

    Using pieces of ABS I filled as many gaps as I could and began to fill what was left with filler.



    That is where it lies at this point. I have to let the filler dry properly before shaping.
    I have a hunch it will take much more filler and far more sand papering to get the shape I am looking for.

    Let me know what you think so far

    I am excited about this. Will follow with interest. So I assume you will not be able to listen to the radio anymore then?

    Update

    So here is where it stands as of right now.

    I filled some more spots, sanded a lot more and then sprayed on a coat of primer.
    When working with body filler, you do not know whether you have filled all of the gaps or sanded down the high spots properly until you get some paint on it.
    The primer also acts as a filler for shallow scratches and cuts caused by the sandpaper.

    I test fitted the tablet to double check everything still fit. And it did...just



    There were still some shallow gaps and 'bumpy' bits so I kept sanding.

    The filler I used for the rest of the project isnt suitable for filling tiny gaps. Instead, I purchased some spray on filler and am using that to finish off the shaping of the tablet bezel.

    I figured I should properly check to see if it still fits.
    After persuading the old dash with the dremel and a few sharp pulls it came off and I test fitted the new one



    After sitting there for a few minutes pretending I was driving around with my fancy new head unit. I pulled it back out and kept sanding

    I think it looks good so far.

    I'm still waiting on some cables and other bits and pieces to check that the tablet does what I want.

    Going to organise my colour matched paint tomorrow, purchase a couple of switches for my battery voltage meter, install my new speakers and install the amp under the passenger seat. One step closer to being finished!

    Actually, using SDR touch I can connect a USB TV tuner like this and use that to receive FM radio or even use it as a scanner on police frequencies

    I don't often listen to radio but I feel it is worth including just in case.

    What you can see in the image is just a custom wallpaper thrown together in photoshop to give an OEM look and make it easier to select specific functions on the tablet while taking my eyes off the road for as little time is possible.

    This is an older version. If you swipe to the left on the tablet you get the 'offroad' apps
