Budget Nexus 7 in dash install

Hi,

Obviously I`m new here, so I will introduce myself first.
My name is Toma and I`m from Bulgaria, Eastern Europe.

Some time ago I bought this `92 Caprice Classic L03 with 59K miles on it.



The car was in overall good shape, but there were some minor issues with it.
One of the issues was with the stereo... popping sounds, reduced sound quality...etc.
As I said - I`m in Bulgaria, which is on the other side of the planet and some 1.5 DIN genuine GM stereo will be shipped to my place with the price of gold.
Also I wanted some goodies on top of the AM/FM receiver and cassette/CD.
I found only 5-6 aftermarket 1.5 DIN head units and all seems to have old-fashioned capabilities for me - the top version was with mp3 support.
Then I started to research the ideas for 1 and 2 DIN Multimedia.
1 DIN seems to fit ugly in the original stereo location in the dash, even with a quality "1.5 to 1 DIN" conversion bracket. All 1 DIN Multimedia's are with motorized displays. I`m not a big fan of the crappy moving mechanism and it is impossible to use it with a proper display angle because of the dash specifics.

Then it comes the 2 DIN - to fit it right, you need to make some serious cuts in your dash and finally it will look even uglier than the 1 DIN.
On top of that, every single universal 2 DIN Multimedia unit needed it`s face plate visible and reachable in order to operate with the physical buttons of the head unit. This makes the Multimedia to pops-up in front of the dashboard with 1/2 inch..... UGLY!

I was sad....
So good car, with no good aftermarket stereos at all...... with "close to standard" installation.

Then I started searching for what you guys ( in the States ) did in order to solve this issue......... and after awhile I saw a thread with the iPad installation and a part of the answer came by itself, but without the iPad in mind

I grabbed the Nexus 7 from my kid while he was playing some game and after some measuring, reading, drilling, cutting and soldering - everything seems to be close to perfect and I`m happy now


The dimensions of the opening for the original stereo are short with only 1/4 inch on the vertical. Some sanding solved the problem.


The good old Bose Silver which was retired with honors.


The space where the original stereo lives is now free and I can hide there the cabling, the relay, the DC converter and the USB extension cable.


The black plastic which holds in place the original stereo is assigned to the same role - holding in place the dummy "stereo" made from playing wood


The plastic back from the flip-cover is used as a mounting bracket.


The Nexus is already in working condition, set-up for in-car use. The red/black wire is the extension of the power button, which I mount on the face of the dash.


Previously I said that I hate ugly things - OK this is my ugly bass-box and my ugly amps, but this is a temporary mounting point for everything and in the summer I will make my trunk area much prettier.
The black bubble thing in the left corner of the photo is my LPG tank.

The total investment is ~415USD ( no labor - self installed )
This total includes all the parts listed in the information of the video........ without the price of the Caprice itself

For full screen demo - https://www.youtube.com/watch?v=09vMRx-NtZo

Everything ( except the DC-to-DC converter ) was 2nd hand in close to perfect visual and working condition!
The shiny button in the left of the head unit is the power button of the tablet - I made it because if you need to push it by some reason ( the unit somehow hungs for example.... ) you need to disassemble the whole dash and I tried to take some precautions...
The black knob above it is an external volume control - this I made for situations when you need the sound volume reduced fast ( boss calling.... officer talking to you... and so on )

For all the signals i used the original stereo cabling. The only additional cabling is the positive wire from the battery to the amps in the trunk.
My reverse camera is still in progress but I will update you soon. It`s the same for the FM receiver.

I hope you like the general idea.



Merry Christmas!

BR,
Toma

Thanks!

If you know what you are doing and you are good with planning it is more than easy. All other things as cutting, soldering, drilling and so on you can delegate to someone trusted in case you don`t feel comfortable doing it.

I give it 4 of 10 as a difficulty.

If you are interested, I can provide you with more detailed information - the full list of parts you will need, what measures you need to take, where you need to cut/drill/solder and etc.

Also consider that in "fixed installation" mode you are able to update your music/video library using an external storage device as USB thumb drive or USB hard disk. This is possible because Nexus 7 does support the so called "USB Host mode".
But in case you are not interested in this solution - you can use the regular sync via WiFi or BT.
Also this "USB Host Mode" allows you to attach some other USB devices to your tablet and to use them.
For example - I use a simple DVB+T tunner as a FM receiver and for controlling it I use a software called SDRTouch ( available in Google Play Store for free ).
The other USB device which I will use is a USB EasyCap Video Capture. It will be used as a video input for my reverse camera, but it is still in progress.


BR,
Toma

Nexus Install: Power Button

Toma,

How did you hook up the power button?

Any specs on the button/switch you used?

Thanks,

Bill

Hi Bill,

I have modified the flex cable for vol +/- and power on/off.
When you disassemble the tablet, you need to remove the flex-cable from the tablet. The you need to peel off the white nylon which covers it and you will see two metal spots - outer ring and a dot inside it. When you press the button, you actually make contact between then, so in order to make it - you need to solder some thin wires there, but you need to be careful to keep the outer ring from contacting the inner dot and vice versa.
Also you need to be careful with the flex cable - to not rip it apart while removing/installing and to not molten in during soldering.
Some hints here:
1. When you decide the location of your button and you mount it - measure the distance between the button and the tablet ( for the wires) and multiply it by 1.5 or may be 2...... The longer is better and there is plenty of room behind the dash to hide it.
2. When you solder the flex-cable to the button - first test it and make sure that you will not destroy the soldering and/or the flex-cable during the installation of the dash.
3. Once you are ready - cut the wires in the middle of the length ( flex-cable disconnected from the tablet or the battery of the tablet removed ) and there you will solder some male/female connectors - they help allot when by some reason you need to remove only your dash, but not the tablet - just disconnect the coupling in you are ready.

Regarding the switch/button - no specials there - just an ordinary N/O press button... that`s all you need to make it as mine... but may be you will choose the button to comply to your interior/dash/ and/or other buttons you might have.

If you don`t trust yourself for this task - give it to someone else


Now some updates - I have ditched the primary idea to use my in-dash tablet for the rear view cam, but instead I am now in the middle of installing an overhead console from a `97 Blaser.
I have removed the temp/compass display and some 4.3 inch TFT display will be placed there and will do the job.

I will add some pics later.

Cheers,
Toma

Tablet Install

Toma,

Thanks for the reply. I'm putting together a parts list and laying out a plan.

Have an overhead console sitting here also.

Details when these things get done.

Bill,

If you need any assistance with the parts list or the software tweeks to get the job done - ping me

Now - you recognize the Blaser overhead console.
What you see atteched to it bezel of the 4.3 inch TFT which I will use for my reverse camera.



Some fiberglass job in order the overhead console to fits the headliner in the Caprice.



And some other fiberglass job for the TFT to become part of the overhead console



Still not finished, but you get the idea
