This is fantastic! Thank you for posting it. I have started building mine but have come across a couple of things I need to add or change. When it has been posted I can’t wait to see your schematic and script for the relays, that’s one thing I am missing. I can help you navigate the custom obd gauges and pid’s as I have set them up for my car.

How a complete build in detail from scratch to build the head-unit in several videos would be handy . detailing all connections, software, adding different module and setting up, especially things like 4way audio, radio tuner, cameras, etc

So cool! I'll be super keen to also add reverse camera. 360 degree camera, DVR, 3G. Possibilities are endless with such a cool custom build! Gonna keep tuned to this

That's awesome. It looks factory installed. I really look forward to seeing more about this. Thank you for the video.

Awesom Work! 👍👍👍 Yes, "car computers". It's too much a luxury to own a car in Singapore, never thought I would enjoy watching something like this, until now.

Awesome, man! i've been thinking about making a build like this myself, was holding back and waiting for a properly working android build for Pi. I haven't found a head unit for my car that i'd actually like for almost 10 years now. thats frustrating that you have to build something yourself to make it actually good. My plan was to not use a built in amp, since my speakers are powered by an amp anyway. And i'd like to find a proper good sounding sound card for the pi, and one thing i have to solve is that i definitely need a rotary volume switch and maybe couple of buttons for next and previous tracks.

Ah dude, SUPER sick build, love your work! definitely thinking of doing something like this in the future.

I'm doing a conversion van custom tech rebuild but I want to make it my own. This is dope and perfect for the type of ideas that I'm looking for.

This is so cool, thanks for posting this and can't wait to see what's next. I bought a rock pi to try doing this before the pi 4 came out but unfortunately due to lack of software and some breaking the as slot off when it dropped on the floor, I was unable to complete that. Might give it another shot however using this setup.

You'll definitely need to get an anti-glare screen protector, that glare will become a problem when least expected. QOL improvement.

I've been playing with streaming music for years in the car. I first mounted an old tablet, which worked for 2 years until the screen died from the heat (touch screen connections pulled off). This let me know that only quality LCDs should be used. I've been running an RPI (3?) with Openauto Pro in the car for years now with the official 7" RPI screen, and it's worked very well except when Google updates their software and it breaks for a little bit. Great to see this video about it. Very nice!

I have been wanting o do a modular pi deck forever! Bravo!

This channel is gold mine of knowledge .

welcome to the Family! ;) ive been a memeber of this project since update 2.0

I was about to mention about touch screens being really bad for volume control when you mentioned it. Another thought would be to rig up a jog shuttle/switch instead of a basic volume control so that when you are in the map view it could allow you to pan and zoom around the map view without having to drag the map via the screen.

Looks very clean. Seems the relay contactors used did their job. I may have to give this a shot one day. Greatly appreciate the video.

Im doing a similar concept on my truck, and this video answered most of my questions faster than i could think of them. This is awesome

Looking forward to the updates!

Very nice work on your build. If its running warm you could mod one your vent ducks inside to blow down with little hole inside to help keep cool if your running your a/c or such.

Very nice install and good to see a Subaru getting some love. I have a Tribeca so this would be a bit too involved to get working in that since the screen is about 10 inches above the controls. But the head unit I put in my Jetta has a/v inputs so I could add a pi to it.

I was looking on Amazon for a second monitor for my head unit and saw that they make mini HD I displays for Pi. Did a quick search on YT and landed on your video. I really like this build. This is great! This auto pc has serious potential. If I still have trouble with my Pioneer MH1700NEX, I think I'll try building my own micro pc like this. I might go with a 10inch screen though, if it'll fit nicely.

Thanx for posting. Now you have a platform to test the other open source projects out as well. Hopefully you will include some of the full android ones.

love that set up real clean iv been working on a similar set up in my mustang. I also run my custom ecu in mine with tuner studio installed on the head unit as well so i can back out the stereo and open the app from the desk top on it. not only do i have all the gauges but can also custom tune my car right from the head unit. if you wanted to take your car to the next level with a diy full stand alone ECU look into making a speeduino and you can tune it through your raspberry pi head unit. also I just subscribed like your content.

Not going to lie... I was going to call you out so hard about the VPN service claiming to not keep logs. However, after doing research into them on my own, PIA really doesn't keep logs of any type. I must say, I was wrong and this was a great sponsor shoutout. Thanks for the link, bro! Great video on the Pi head unit as well. I've been waiting for a few months now for someone to drop this so I can follow along and install one in my Nismo RS. Just liked and sub'd, thank you thank you!! :)

Bravo! Simple and effective. I like how you approached the safe shutdown and parasitic draw issues. Would like to hear more on audio quality. On my setup, I'm now only using the USB sound card for mic input. I installed a PCM1502a dac for sound out which has much better sound quality. I've seen some guys using HiFiBerry for the same thing.

Loved building this , so thanks for all the info Has anyone who has built one had any issues with audio crackling ( quite loud ) Used pretty much same parts as in video ( I have looked through forums )

Wow, what a nice random find. I had almost the same idea, and I have almost the same car (sportswagon). As soon as I saw the plastic center console on your desk I was like "hold on a minute". Anyway, my idea was to have a dual screen setup, one like you did but also a smaller one mounted to the other side so I could have closer access to controls but also I could keep like Navi up and still play a movie or something along those lines.

If you have any issues with it keeping it cool you could always use the ac ducts above. I would 3D print some small tubing and adapted to the Ducs above so that way it blows cool air on the Raspberry Pi. But you have to figure a way to shut off the airflow during the winter the heater is not blowing on it

When she doesn't say I love you back

I've managed to get FM running on a Pi using one of those cheap $10 SDR dongles that have the RTL2832U chipset. That chipset is probably the most commonly used and supported chipset for SDR devices on the Pi.

Finally my love of pi and my love of subaru have came together as one. Been planning to do this myself but with 2 screens (sat av and infotainment)

Amazing .. waiting for the FM module update.. Great project ... Congratulations!

I like your project! Looks great. Did you consider extending the front out so you could mount a much larger screen? You could also add standoff's to raise the raspberry pi up a few mm to assist with heat dissipation. If you need to adjust the base plate to allow for the height, you can add side 'wings' and lower the base plate and use the wings as new attachment points to the double din metal frame. The wings could be 3d printed and glued or screwed to the base plate, then tapped and screwed to the metal frame. This would give you whatever height you might need and allow for better heat dissipation. You might even add a layer of insulation between the pi and the base plate to protect the plastic. Perhaps drill some ventilation holes in the base plate to assist with airflow, even making a back plate for the lower area and add an intake fan, and add an exhaust fan up high to get that airflow. Again, with standoffs, if you have holes drilled below the pi, the flowpath will have cooler air pulled in from below, then up through the holes, thus cooling the back of the pi, then out the top or the back plate. It would require 2 more fans, but you could easily run much larger fans - even perhaps have them controlled by the pi with a couple of temperature thermocouple's/sensors placed wherever you think best - It should be no big deal to add fan speed profiles etc... Good stuff! Call me impressed.

Love it! My next project. Keep up the great vids.

Hell yeah a tech channel and car channel. Will go together. I picked up a raspberry pi cuz I'm interested in learning a little bit more about PCS programming, coding, networking and all the other little things that are involved with it LOL. Not trying to be some mad computer scientist but I do have an interest in it. All of that because I have a love for cars and I want to understand the electrical system a little better. I have two cars that are from 1988 very little Electronics in them. So making the stereo out of a Raspberry Pi is dope. I'm also interested in a GPS for the cars made out of a Raspberry Pi. The ECU in my 88 Chevy is tunable and I would like to make something out of the Raspberry Pi to get live readings of the ECU. The reason I want to use the Raspberry Pi is because a laptop is just too big. If I can make something like that the more than likely I would just mount it in the dash with a 7-10in IPS touchscreen display. So yeah the 2 channels would work. If anything I want I want to is is possible and you know let me know.

I learned to things from this video. #1 this is a huge project and i probably wont be able tp do it for a long time. #2 your incredibly smart and i appreciate the time you quality of your videos.

Insane build. Love it!

SSD is absolutely recommended especially when you use Android Auto. After a few weeks of use I had serious reliability issues with SD cards (system was not booting up or only after multiple attempts)... No such issues after installing an SSD.

dude love result!! Brilliant OEM look

I've been working for some OEMs' "real" infotainment systems. This is impressive.

OK, thanks for the video. This is the first time I have seen OpenAuto and it's cool.

This is awesome! Do you have volume controls on your steering wheel? My 2010 outback does. You'd probably need to use another anduino to feed the input to the pi though. For radio you could probably use an RTL-SDR, I'm pretty sure they work with a pi.

Awesome video! Gonna be doing up my car over the next few months too, just got a Thinkware U1000 dashcam to get started, would be really interested in seeing what ideas you have!

THAT IS SICK DUDE i had an idea to make kind of an mp3 box with a pi and one of those cheap 3.5 touchscreen cases but power it from cig lighter and hook it to aux for the ride. but you doin big things

I used a UPS hat instead of a relay setup. I got a buck converter to take the 12v accessory from my truck and put it down to 5v 3a on two separate usbc cables. The UPS automatically turns on the pi. Also the UPS is able to do a safe shutdown of the pi when power is lost (when I turn the car off). And it holds time on the pi!

Very neatly explained. I will soon start installing openauto in my car. The only thing I can't find is that on your drawing and the script for the esp. Only 1 wire goes to the relay. But in your video I see 2 wires. I understand that's for the double relay. 1 for the gpio and 1 for the global_en. But I don't see whether that has been incorporated into the script that I have to put on the esp. Thank you for the clear explanation. Keep it up

That cracking sound cracks me up

Dope video, thanks brother

I would add a forward AND reverse cam for those times when you have to park and there is virtually no room. As an even better solution, you might want to get a recording front and reverse cam to record what happens to your car when you are away from it.

Great job. I wish that I was younger and could take on a project like this. Once again, good job Don!

I was thinking of doing this with my E46 Sport Wagon, but I have 2 crazy power amps that shot my bass through my 12” subs, and sick voice set up…would your idea work to run with my existing setup? Or am I limited to just that 50 watt amp?

Nice job. The menus seem quite slow and laggy though, probably due to the SD card. I'd definitely recommend booting and running the OS from a USB 3 HDD or ideally an SSD. Also, given how unreliable SD cards are (especially in RPIs) you'll probably find yourself needing to remove the unit to replace it at some point anyway.

You may want to put a little delay on the relay to turn on the relay. Reason for this is because when you start the car you'll get accessory feed for a few seconds, lose it while cranking the engine and get it back once the key is released from the start position. Basically causing the Pi to start booting, get interrupted and then start booting again

I really like this video, what a fun build.

Love this kind on projects. Good work.

That is neat! I little bit of warning about peeling the plastic off of the screen is(or any other electronic for that matter), make sure that the system is shut down. and disconnected. The chances might be low but the static electricity from peeling the plastic off can damage your system.(Dont ask how I know)

Great overview. I’m considering an Arduino Nano as a voltage sensor to detect accessory voltage instead of running 2x relays. Do you have a thought on that?

Ok so the amp for the speakers since you are only using headphone out you only have left and right am I correct? You will not get Fade and Balance, it would be one or the other. Just got the AMP in and haven't tested anything since I am lacking some parts still.

How did you manage the wiring harness from car to pi? Do you have steering wheel controls?

I had this on my to do project list :) good job mate !

Great video, loved it and nice job on the head unit but whatever was clicking and clattering in the audio drove me absolutely nuts lol

awesome video. I wanted to do this for my classic car, however I dont want to delete the old radio because it is original, but I found a spot I could add a raspberry screen. I just want to use the raspberry screen for a backup camera and map directions, I have already retrofitted bluetooth into my factory radio and a sound system, would it be possible for my one single phone to connect to both my bluetooth radio as well as the raspberry pi at the same time. displaying only the maps to the raspberry pi and the music to the radio?

For Fm radio you might try one of the RTL-SDR dongles it might work. It is a TV receiver meant for European TV that makes it a broadband scanner.

Awesome video! I have always wanted to do something like this. I have an external amp so I would need to figure out how to do RCA outs or maybe a DSP.

Hey, I am currently working on a fully custom 1988 Nissan Pulsar NX from the engine bay to the rear bumper everything custom. I am looking for a head unit that has apple carplay but I can also run a lot more off of it. Like having triggers for my doors to open after the windows have rolled down some, if speed is under 5mph for backup and forward cameras to come into display, controlling LED lights, that sort of thing. This seems to fit the bill perfectly. I was wondering if you ever did put the backup camera in? Also, I am very new with this raspberry pi stuff so I was wondering if you could make a wiring diagram or anything like that just to help me understand how you have the wires and components connected. Thank you in advance.

Very nice. I built one using a odroid xu4 running android, and a TSA8498 4x100w bluetooth amp, using the bluetooth instead of an audio jack for the amp solved the noise issue

I have one similiar project going on, i just have pi 3b overclocked to 1.4ghz, smaller passive heatsink, 4A isolated step down, step up boost converter for 4x tda3116d2, few rca outputs and im using mosfets instead of relays, i still need alot more and might use my 2din alum case as heatsink.

The looks really similar to a similar year forrester. Definately gonna experiment with this.

Did you incorporate any protection on the power supply against over-voltage and reverse polarity?

I have a 04 wrx doing the same project im using a Dayton Audio DSP-408 as my amp but i havt started my project yet so ill be following close.

Sweet setup.. looks amazing..

OMG dude!! I'm in love with this video

AWESOME JOB

How easy would it be to control volume on something like this with a potentiometer? Would that require a setup with a different amp, or can the center tap be fed into the pi somewhere

OpenAuto rear-view defaults to the Raspberry Pi Camera (with the flat ribbon cable connector). There's a Pi-KVM project that recommends TC358743 boards for HDMI to pi-camera port. Then you can chain it with a cheap composite to HDMI converter. It's a bit roundabout, but probably the easiest solution.

Did you end up using a dac? How was the audio with just the amp? Thanks

super clean install! loving it. which bluetooth are you using?

Also did you use the canbus box or can you use it , need car system data . Did you make anything about that ?

reallllyy hope you can help me, i hooked up the same amplifier you used to my car speakers and to a usb sound car(which works with a headset) but cannot get it working, it is supplied with 12 volts and the aux in is connected identically to what you have

How is the audio for calls? One major issue with so many after-market head units are the terrible audio quality for calls (and many cause feedback between the speakers & mic) - if this solution can bring 'first class' audio when driving, then this is a huge game changer! Also, have you figured out if this can handle steering wheel controls?

Did you have to do anything specfic to the Pi to get it to take a touch screen input? Currently working on my own build, but but the touch screen won't work on the pi, but its working fine on everything else I connect?

With the extra heat (for charging), I'm sure you could have the ESP board using a pin to switch a fan on/off too.

Is it possible to implement sleep state to wake the RPI up when the ingnition is ON? Actual Rockchip Android car devices have this and this is huge advantage - just listen to the music right after ignition ON rather that waiting for full boot each time

I'm interested in the Audio section. I am wondering how the balance/fader works when there is only a Left and Right output into either 1 x 4 channel or 2 x 2 channel amps. Have you tackled this problem yet?

do you not need an isolated power supply for the pi to avoid ground audio interference?? Im guessing you will run into a buzz sound or a high noise floor.... you can fix that by isolating the power supply for the audio source from the amp..

What amplifier would you suggest that has outputs for 4 speakers+ a small subwoofer?

Haven't you had any issue with noise with that amplifier? I have a similar setup and get a lot of noise both from the RPI and the car

What do you use for your bench top power supply for the 12V?

Great work. Question for you, please. You mention an ESP to help with turning on and shutting down the Raspberry Pi. What ESP is it? Do you have a model number, please? Thank you.

can you use an RTL-SDR USB TV tuner for the FM band radio?

With that amp and only 1 input signal for the audio are all 4 channels actually receiving a signal? I am doing a raspi carputer in my truck and was using just my factory radio for the amp. Now going full install. Got the same amp as you and just curious if all 4 channels receive signal from the single input

Is there a way to have rca preamps cables to connect to amplifiers?

hey im building stereo from nexus 7 you can use dvbt usb stick for fm antenna i plugged in car antenna directly...for reverse camera im using easycap usb stick

Would it be difficult to add a volume knob to this setup?

@Novaspirit Tech - aside the 3D prints what was your total cost of this Build?

So is it possible to sideload openauto so it can be used simultaneously with Raspian? I currently have a pi4 in my turbo e36 that I use with tunerstudio for tuning and digital gauges but would love to be able to emulate android auto and have it operate as a media center as well and this build seems to be what I'd need, but I don't want to lose the ability to bring up my gauges either. Noob to linux/pi so sorry if I'm a bit daft with it

I wouldn't suggest this to most people, but you're nerdy enough. You should drop a CAN-BUS Tx/Rx into the mix (there's even a great hat for the Pi). You can then access the car's data bus directly, and gain control over everything, including environmental, and any other electronics in the car (steering wheel controls!). The accessible OBD-2 ports block a lot of data and are largely read-only. With a performance car like your WRX, you'd get gobs of awesome data straight from the ECM. It also has the added benefit of being able to wire into the stock wiring harness nice and clean. You may have to Wireshark your bus to sniff the variables for awhile and map them, but totally, totally worth it.

If it were me, I'd go for an I2C FM controller like the TEA5767 or similar. Should be very low power. I don't know if it supports RDS data, but that would be cool too

I'd like to see you do something with a factory head unit, and have you add Android auto or Raspberry Pi to it.. like a basic Factory head unit with only a 5-inch touchscreen..lol.. that's what I have and I'd like to upgrade it or add something to it..
