Intro
So I had this crazy idea about fitting onboard computer to my 04′ Honda Accord Tourer (Exec trim with premium speaker system – non-navi version).
Been googling this and digesting available information, finally stumbled upon this excellent Engineering(DIY) project, blog and associated forum – and decided to give it a shot.

Accord Radio Plug – source of power
One thing worth noting, in order to power things up we need access the radio plug. To access radio plug I had to remove the whole stereo/disc changer unit. Sounds tricky but this lovely chap has got it covered for you. I didn’t buy any stereo removal tools, simple wide steel spatula/scraper did the job. Once radio removed I could access the radio plug so carefully removed a bit of isolation from three wires and soldered my RPi2 /LCD power cables with fuses.
Was a bit scared of that part but it took less than an hour altogether. Jolly good.

What’s left on my to do list
- Adding pyOBD based KODI plugin for engine real-time diagnostic, similar to the one from this page.
- Rear seats, adding headrest mounted monitors for kids (via HDMI splitter).

Some final thoughts
One note, if you would prefer to mount LCD a bit higher, say right above ventilation ducts, you might be interested in fitting this plastic panel instead of Double DIN fascia I used. Just an interesting alternative that was mentioned on one of the forums, alternative which I wasn’t aware of.
Apart of that, not much left to say as Andrei’s blog has most of the aspects covered.
But obviously if you have any Honda Accord specific question feel free to drop a comment here.
Many thanks to Andrei for publishing all necessary info and for keeping this awesome project alive.

Did you build the center console and have the woodgrain film applied on it? Like the Linux Jetta at dashpc.com?
Nope, that sound too tricky for me 🙂 I just bought this thingy here: http://www.ebay.co.uk/itm/221777938814

Hi I just wanted to know what skin/theme you are using with Kodi. Thanks in advance
Hiya, this skin has been made by good folks at http://engineeringdiy.freeforums.org – it’s pre-packed with with image prepared by Andrei, take a look here – link.
Istnieje możliwość zaimplementowania w kodi obsługę zastawu głośnomówiącego przez bluetooth?
To raczej pytanie na forum Kodi, szczerze to nie eksplorowalem takiej opcji.
W moim przypadku i tak musialem dodac Yatour zeby miec aux-in do radia – i ten model Yatour ma Bluetooth (zestaw glosnomowiacy czy streaming muzy ze sparowanego telefonu). Link do mojego modelu Yatour jest w Shopping List powyzej.
Hey man can you list out what GPS dongle, WIFI dongle and BT Dongle you used?
For GPS, mine is GNS GM23 – but check out this link first, http://engineeringdiy.freeforums.org/viewtopic.php?f=5&t=298
Jestem na etapie kompletowania elementów, mam już wyświetlacz z driverem ale okazał się wadliwy i czekam na drugą przesyłkę z Chin. Mnie najbardziej interesuje, w jaki sposób przymocowałeś wyświetlacz ? Ja wymyśliłem że kupię półkieszeń, dorobię do tego ramkę z polistyrenu. Jak Ty to rozwiązałeś?
Pozdrawiam
Właśnie zobaczyłem fotki. Fajnie że do Twojego auta jest dostępna taka kieszeń, ja mam Peugeota 307 i niestety muszę kombinować. Taka ciekawostka – nie wiem czy wiesz, ale chyba na driverze który posiadasz jest możliwość doprowadzenia +12V z lampy wstecznego, nie trzeba ręcznie przełączać kamery cofania.
Czesc – ja kupilem LCD “second hand”, bez manuala. Ja myslalem ze wystarczy zapodac sygnal na AV2 i to powoduje juz przelaczenie na to zrodlo – kamerke mam zasilona z lampy cofania. Ale takie podlaczenie nie dziala wiec chyba faktycznie musze zdobyc i sie wczytac w schemat 🙂 Dzieki za info!
PIN ACC we wtyczce z AV2 to właśnie zasilanie ze światła cofania. Dostałeś może gdzieś tę 5 pinową wtyczkę? Nie mogę jej namierzyć.
Hmmm, kurcze stary ja nawet nie mam pojecia co to jest ten PIN ACC 🙂 I nawet nie wiem gdzie ta 5 pinowa wtyczka idzie? Sorry.
Ale kombinuj i sie podziel jak to rozgryziesz bo to manualne przelaczanie zrodla to troche jednak faktycznie PITA 🙂
Hey awesome work. I was just curious what GPS module you used. Thanks
Apologies for delay getting back to you, I was offline, camping.
Mine is GNS GM23 – for the list of GPS devices that are known to work go here:

Hope this helps.

Hi man what did you have to do to get around the German language on his Kodi os. I have tried and when I hit the ‘s key to type sudo the system thinks I hit the shutdown key.
Have you tried
raspi-config / Internationalisation Options / Change Locale
Hi there is am busy with a project like this as well did the steering functions work with the raspberry pi
Are you running Raspbian as your OS? What happens when you shut the car off – does it do a clean shutdown?
Yep, it was Raspbian. Shutdown was performed by Mausberry Circuits 3A Car Supply / Switch, they provide mechanism for automating that. Mausberry is hooked up with two cables to GPIO and, if I remember correctly, there is a cronjob that monitors these GPIO pins and triggers shutdown when value on them is 1 (true). Something like that.
Honestly tried the Astronaut flight game recently and it absolutely grabbed me, link https://crushtop.org . This concept feels simple: the astronaut flies up while a number increases, and you must cash out right before the crash. Bigger risk means larger payout, so timing feels key.
At first I bet small, mainly to understand the mechanic, but within several bets I quickly felt a moment. This adrenaline is insane each moment, especially when that line starts going up. The interface is simple, nothing useful interrupts, and everything loads perfectly.
I also tried on my phone and the game performed great. Withdrawals seemed quick, which is essential to me. I personally didn’t notice any shady at all. Overall, the Astronaut crash experience is engaging. When you enjoy high-risk casino games, it feels like definitely worth playing.
Just keep in mind: play with control.
In the modern digital era, international interaction has increased dramatically. Individuals from diverse linguistic backgrounds are connecting more frequently across work, leisure, and academic environments. However, linguistic differences continue to pose a major obstacle.
Conventional translation solutions such as mobile apps or handheld devices often require manual input. Because of this, a growing number of people are turning to AI translation earbuds to improve real-time interaction.
AI translation earbuds combine artificial intelligence, speech recognition, and machine translation to deliver instant language translation. Without the need to hold a device, users can communicate naturally as speech is instantly converted into another language.
One of the biggest advantages of this technology is their convenience. Compared to mobile apps, they remove the need for screens, making conversations feel more human and engaging. This benefit is especially valuable when real-time response is essential.
An additional advantage of modern translation earbuds is their support for multiple languages. Many devices offer translation across numerous languages, allowing them to be used in diverse linguistic settings worldwide. Advanced platforms also include regional accent recognition, improving accuracy and comprehension.
Precision also plays a crucial role. Today’s AI-powered devices are powered by machine learning technology to deliver more natural and context-aware translations. In contrast to basic translators, they learn from data and usage, producing more reliable translations.
AI translation earbuds are increasingly adopted in business settings. Global conferences frequently include multilingual teams. Through intelligent translation solutions, communication becomes faster and more efficient. This technology helps reduce misunderstandings.
Tourists find great value on intelligent earbud translators. During sightseeing and transportation, misunderstandings are common. By wearing translation earbuds, people can communicate more comfortably abroad. As a result, this creates a more enjoyable journey.
Another emerging use case for smart translation devices is personal language development. Students can compare spoken languages instantly, supporting faster learning. With continued use, language familiarity can increase naturally.
Privacy and comfort are also important considerations. Today’s translation earbuds are designed for long-term wear. Advanced versions include noise-canceling features, supporting clear communication. Additionally, translations are delivered privately through the earbuds, which is ideal for sensitive conversations.
As technology continues to evolve, intelligent earbud translators are likely to gain wider adoption. Future developments could offer improved accuracy and reduced latency. Ongoing innovation will make global communication easier.
In conclusion, AI translation earbuds represent a significant step forward in overcoming language barriers. They combine convenience, accuracy, and real-time performance, these devices enable smoother and more natural conversations. With increasing global demand, such devices will shape the future of communication in global society.
