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.
There are so many AI chatbots available today—ChatGPT, Claude, Gemini, Grok, DeepSeek, and many others. Which one do you think is the best overall, and why?
I’ve also been working on my own AI chat project and would really appreciate your feedback: https://rabu-ai.org
