Renault Clio Head Unit
Jovanna Ponder
There are boards that allow for a constant powering directly from the battery that monitor the ignition pin and send a command to the Pi to trigger a safe shutdown when the power goes, and I aim to replicate that function using an arduino. Kinda.
The Pi will be connected to the Battery directly using a fused, 5v connection. The arduino will be powered by the 12v ignition power, and both devices will be connected together via their serial pins.
Recently I was researching some options to reignite my Pi Car idea, and I came across the OpenAuto project, which emulates an android head unit. This intrigued me; it had all the capabilities I was needing, and it was achievable with the parts I had to hand, give or take a few missing items.
There is an Open Auto pro image available for a nominal fee, but there's also a free, open-source option called crankshaft. This adds a friendly GUI for the Open Auto project, and seems to work well.
My currently car, a 2006 Clio Mk3, has a simple head unit and a small clock pod in the centre of the dash; there was a sat nav version which came with a larger pod for a screen, which would be a a great place to mount a Pi Touchscreen.
I have picked up this pod from a scrapped vehicle, and am going to use a dremel to remove some clips which prevent it from fitting in. Once fitted I will be able to put this pod in the place of the old clock, and move the old clock down below the centre console.
In another project (my sample pad controller and electric drum module) ibe changed my plan of attack, and it has left me with a M0-based board from dfrobot and a music playing shield, complete with SD card slot.
Combining this little music player with a small Nextion touchscreen I have (uses software serial to communicate) and an esp8266 to allow a connection to my phone and perhaps an FTP server to drop music onto the SD card and that could leave me with a really handy little player.
One method I am interested in is making the filesystem read only; If i can setup a read only system nothing will need to be saved during a shitdown sequence and will therefore protect it during sudden powerless.
Just a quick post to share this link that uses an USB Powerbank as a UPS-style system, using a network switch to simulate the power outage (when the power is cut to the Pi and the Network switch the network connection goes down and the Pi detects it).
I've recently made a music player for my partner as a little home made Christmas present. It's great; runs RuneAudio, has a memory stick full of her favourite albums, has Airplay receiver capabilities, and is generally a great little system.
It's a piece of tech that connects your phone to the head unit in your car so that you will see a simplified version of your phone screen on the infotainment display. You can watch the video below that explains carplay features

I just installed Spotify (the new version with the UI overhaul) on my HTC Droid Incredible 2 Android smartphone (running 2.3.4). The app works great with headphones, but when I tried using the app in my car with my phone paired to the car's audio system via Bluetooth, when a song is "playing," no audio plays through the car speakers (or through the phone speakers either for that matter). That is, it seems to think that the sound is playing through the car, but it actually is not. The issue isn't with my phone itself because other music apps work just fine with the car speakers (Winamp, Pandora, HTC's music app).
We're on the same boat. Sometimes I can listen to my music from my Samsung Galaxy S2 (Android) through my Mini Boombox loudspeaker using bluetooth. And sometimes there is no sound at all through my Mini Boombox even though the bluetooth is on. Really irritating.
I have a similar issue, but I can't get the newer version of Spotify to play through my headphones, phone speaker or bluetooth since the auto-upgrade to the latest version a week or so ago. The song looks like it is playing, just no sound!
I'm having same issue. Little different though: I can click a song to play it, the next song on the playlist does what you're talking about, I have to click skip back and skip forward to get it to play, and it does it just playing from phone speakers as well
Playback over Bluetooth or Aux (headphone) begins just fine for the first few songs. Eventually it will "look" like it is playing, but there is no audio. Hitting Pause, waiting a couple seconds, then hitting Play will cause the song to start over from the beginning with audio output again. The audio drops out once the next song starts playing though. This gets really annoying, since I have to do it for every song once it starts this behaviour.
It does this with the screen on or off too. However, I was able to successfully stream for about an hour (until I lost service in the mountains) by starting playback, and then returning to the home screen and using the Widget to control Spotify. So apparently the issue is related to having Spotify as the foreground app. Scratch that theory, it started doing it again today while I was testing it with the Widget. Haven't figured out any kind of pattern to reproduce. Sometimes it works great, but most of the time it doesn't.
you just never know what new whacky behavior you're going to get with this app. BT is my 90% use case, as i listen in the car mostly. about 50/50 that it will play after making the connection -- half the time i have to force kill the app and restart it. on disconnection, anything might happen -- it might start playing randomly several minutes later, it might crash the app, it might not play anything again until i force close it, just to name a few.
spotify has stated more than once that BT is not "officially supported" - -getting anyone's attention about this just ain't gonna happen -- even though every other reputable music player for android handles BT, and even transmits track info. i would imagine on the priority list, this is way way way below landscape mode (which we've been waiting for for over 4 months), and GBs per month of rogue data usage...
yes it is true. if you search the forum, you should be able to find more than one post where a customer rep states this. i remember it distinctly, because of how absurd it was that the old app actually had a link to android BT settings (which apparently wasn't "supported")...
Having this same issue, it has worked just perfect until the last two months. Ever second song (or so), the audio disapperas, while the song is playing just fine. Putting Spotify to Offline mode and back has fixed the issue, but bit clumsy as you need to keep doing it all the time. Using Android 4.2 on Galaxy Nexus. Issue was also on Android 4.1.2.
Good time to give Xbox Music Pass a try as soon as the Android app is released. Sorry Spotify, not "supporting" mobile devices and Bluetooth is your loss. I've heard these "mobile devices" are pretty popular nowadays.
I reconnect my head unit to my phone, and it's fine. I think spotify doesn't realise it's paired and should be outputting to bluetooth, and I bet if I plugged headphones in I could hear it playing (but lets face it, why, when I can bluetooth it into my $2,500 alpine system...)
After I did those and re-login into the Spotify app, after a few songs I encountered infamous "No Internet Connection" error. Other Internet apps are still working (Browser...) So I turned off the WiFi and then turned it on again. That fixed it. So the Spotify's handling the WiFi error seemed to be a problem in the start.
After that, I started streaming radio and things looked a lot better. Now it doesn't seem to encounter the radio with no sound and internet error errors anymore. I also tried another device (HP Touchpad with CM9) and that looked ok as well. I'll continue to observe how things go but so far it seemed to be ok now.
