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.

聽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 馃檪 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 mo偶liwo艣膰 zaimplementowania w kodi obs艂ug臋 zastawu g艂o艣nom贸wi膮cego 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 element贸w, mam ju偶 wy艣wietlacz z driverem ale okaza艂 si臋 wadliwy i czekam na drug膮 przesy艂k臋 z Chin. Mnie najbardziej interesuje, w jaki spos贸b przymocowa艂e艣 wy艣wietlacz ? Ja wymy艣li艂em 偶e kupi臋 p贸艂kiesze艅, dorobi臋 do tego ramk臋 z polistyrenu. Jak Ty to rozwi膮za艂e艣?
Pozdrawiam
W艂a艣nie zobaczy艂em fotki. Fajnie 偶e do Twojego auta jest dost臋pna taka kiesze艅, ja mam Peugeota 307 i niestety musz臋 kombinowa膰. Taka ciekawostka – nie wiem czy wiesz, ale chyba na driverze kt贸ry posiadasz jest mo偶liwo艣膰 doprowadzenia +12V z lampy wstecznego, nie trzeba r臋cznie prze艂膮cza膰 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 馃檪 Dzieki za info!
PIN ACC we wtyczce z AV2 to w艂a艣nie zasilanie ze 艣wiat艂a cofania. Dosta艂e艣 mo偶e gdzie艣 t臋 5 pinow膮 wtyczk臋? Nie mog臋 jej namierzy膰.
Hmmm, kurcze stary ja nawet nie mam pojecia co to jest ten PIN ACC 馃檪 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 馃檪
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.
