Since I'm not listening to the radio, I wanted to get an evolutive solution to listen to the music.
I also wanted to be able to use the GPS, monitoring application.
I had a Samsung Galaxy Note I wasn't using anymore, so I decided to integrate it into the headunit console.
Despite armored cables, I had a lot of interferences with the Note, so I decided to buy a used Nexus 7 2013 and to integrate it.

Here's the start of the project.

So I re-used the console I had modified for the Note in order to cut and modify it for the Nexus 7.
I removed the carbon wrap from it and placed the Nexus 7 to ensure it would fit.



Since I performed a lot of modifications on the console, I re-inforced it with fiberglass to keep it rigid.




While waiting, I cut the console to fit the Nexus 7



Once cut, I tested it



It fits great, cool
Once this was done, I cut the fiberglass I added to remove what wasn't necessary and I covered the front with a soft touch wrap.


Here's the final result:

Nexus 7 Off:


Tablet booting up:


Home screen:


Music:


Waze:


Torque:




Nexus 7 installation software:
ROM: OmniRom with everything useless removed (tablet starts up in less than 20s)
Softwares: PlayerPro for music, Waze for Navigation (Google Maps is still installed), Torque for monitoring, AutomateIt to perform automatic tasks, AlwaysOn widget to avoid screen dimming during the day.

I configured 2 tasks in AutomateIt:
Power off when not in charge
At 7.30pm screen is dimmed to 20%

I'm still looking how to move the navigation bar from bottom to left (tried with Xposed + Gravity Box but didn't worked).
I also still have small interferences don't know why, I checked all grounds, everything is fine.

 

Nice! How did you connect the nexus to the car speakers?

 

Very nice, I wonder if you could fit a double din screen where you put the tablet.

 

I have an amplifier behind the driver seat, I connected the Nexus using a Jack/RCA cable.

 

so you don't have a head unit? it just goes

nexus 7 into amp and amp straight to speakers? do you have a volume control unit?

 

No headunit yes, Nexus to the amp and amp to the speakers.
At the moment, I control the volume directly on PlayerPro but I'm thinking about how I could connect the volume buttons on the Nexus to the volume buttons on the OEM remote volume control.
