N2+ and VU7A+ into Renault Laguna III

Post by zyssai »

Hi everybody!

I'm french, i own a Renault Laguna III mk1 year 2008.
Let me show some pics.

Image
Image
Image
Image

I'm on love with this car, but original multimedia fonctions are totality absents.
There is no aux input (i've added one by myself), no bluetooth audio (only phone calls).

Before i buy this car, i had a Renault Laguna II, i installed a real computer inside.
You can see here:
http://forum.caraudiovideo.autodeclics. ... 486#p50486

But now for this Laguna III, i need something much easier.
I really wanted to keep original aspect of the car.
So i really wanted to keep screen at the same place, integrated into the frame of the car.

I needed a system with possibility to control it with steering wheel control.

I used by the past Centrafuse into Windows, but it's discontinued.
Linux is to hard to use for me.
There is OpenAuto, but i don't like the final result.
AndroidAuto is not as practical as i want.
AndroidTV as no much apps.

So after reflection, my choice was Android.

I thought to a tablet, but not easy to integrate.
I thought to an Android box, with lcd touchscreen.
So i discovered that touchscreen is really hard to make it work with Android, as it needs to integrate drivers into kernel. I don't know how to do that. It's too hard for me.

After a lot of research, i found Odroid!
What a thing!

After checking the screen size, and possibility of the sbc, i ordered N2+, with Vu7a+ screen.

Image

Hard work is coming.. testing differents roms, learning how to use gpio...

I disassembled the steering wheel controller, and made some modifications (it was multiplexed)
Image

Disassembly of the original screen
Image

Here you can see the.... Hum..
Image

Closer look of the N2+, you can see a flat flex hdmi cable.
Right to the odroid, is a regulator. Behind him is hidding a board for auto start of the N2+ when engine starting, and autoshutdown when engine stop. Thanks to joerg for his Amazing app ( viewtopic.php?f=137&t=21386 )
Image

At the left is an old DAC, plugged in USB to the N2+, and in aux entry of an old autoradio, waiting for the replacement by a full digital amplifier.
Image

Hidding the misery... :mrgreen:
You can see a USB cable, plugged into USB otg port of the odroid, in case i need to use it
Image

And it's finally here!!
Image
Image

And with Spotify
Image

All driving commands are working :
Volume
Track prev/next
Changing app from Spotify to Tidal and TuneInRadio
Changing luminosity from 30% to 100%

I will made a video soon.
[Edit: video is here:
https://youtu.be/ms2cDEHobw0
Just forgot to show automatic extinction of the odroid, 10 seconds after ignition off, the system power off itself properly]

Hope you enjoy ;)

Can you tell me where you bought the right-angle thin HDMI cable?

Here is one, they are often called FPV cables.

Sure, it's this one.

If you don't find the good angle configuration, check the store, there is others

Thank you for the information. 1080p is more than enough for my application.

BTW, can you please tell me more about the audio path?
You seemed to use an external USB DAC for HiFi sound.
But, you also connected a line-out stereo cable to the 3.5mm audio jack on the N2+ board.
Do you use both audio outputs to the autoradio aux inputs?
Are you going to replace them to a single fully-digital amplifier? Which digital amplifier do you consider?
Sorry for many questions. ;)

Yes i use external dac, i put it into my car before installing N2+. I connected my phone directly in USB, the dac was connected to aux entry of the old installation.

Now this is the N2+ that i connected in USB to the dac, and the exit of the dac is connected with stereo cable in the auxilliary entry of the radio

I don't know if you know what is a full digital amplifier.
Here is a blog about this

https://soundcheck-audio.blogspot.com/2 ... -amps.html?

The main advantage is that you don't have ground loop issues and something like this.
And it's only one USB cable to connect.

I have one into my home,it's just amazing. But didn't buy it for my car at the moment.

The problem is that most FDA use 30-50VDC to power.
I only found 2 ones that can power with around 14-15VDC.

FX-Audio D302
SMSL Q5 Pro

These are some cheaps ones, but you can google them.

For my case it's just for testing, i don't know if i will keep FDA into the car

Thank you for the explanation. It is clear now.

I just guessed a TAS5756M or similar IC based module something like this.

Very nice setup good work! I'm trying to integrate a C4 into my vehicle at the moment with Linux and VU7A. (I'm Android noob)

I have all hardware ready to install and working on some finalization for the Linux software.

How do you setup your linux? Do you use special interface ?

It is based on gnome with panfrost with some skinning of apps to make it work better with touchscreen. This is the part i'm still working on and where Android has the advantage at the moment.

It's seems hard to have something usable with linux. I would love to use it, but not have enough time to work on it

Don't play music video while driving. The video scene is quite attractive. :twisted:

I have received my new amplifier.
It's Chinese one, but no much money to buy high end amplifier.
4x50wrms, 4x80wmax 4ohm
I need to say that it is really amazing, have great functionalities like parametric equalizer, delay, filter, with Android app.
So I can use it directly with Odroid, connection to the app is by Bluetooth, I just have connection timed out error when connecting with N2+, so I use app from my phone, I hope to find what's the problem.

You can see that I have no need of autoradio now.
I have cleaned the wires, removed DAC because connection between N2+ and amplifier is just done by USB cable.
No analog wire, so no ground loop or shit noise.

Is the connection via Bluetooth?

Thanks!

Sure, it's ELM327 Bluetooth.
I bought it 10 years ago.
I use it with HK Bluetooth Module 2.
I have the same module with Usb connection but not working even with otg port.

It's basic module so don't expect too much from it.
