imwode, you are the first person to attempt to quantify this problem.

For years our forum members have tried to figure out the OEM RES screen and how to get video to play on it without the OEM DVD head. No dice.

I have not heard of anybody figuring out either the soft or hard protocols on this crazy Honda setup.

@imwode, what year/ model is your Ody?

 

2007 EX-L
Don't worry, we are getting there - I think I got the hardware layer figured.

 

There should be av jacks in the third row left side arm rest bin to connect to your analog inputs via aux mode.

 

Yes, but this is so NOT fun (let alone an offtopic )

 

made it work, but suddenly lost interest. Connecting a raspberry pi to the rear AUX without tearing out DVD suddenly seems like an OK idea...

 

Man, I am so interested in this. I'd like to keep the OEM RES while updating to a better DVD head unit.

Please keep us posted on how you are doing this.

What I've done is a MCU pcb that communicates to the head. It has only one purpose - immediately report to the head that DVD disk is loaded; this way the head passes through video and audio signal. With a few more days and little addition to code this can be modified to process commands sent from RES remote control.

As it is now, the POC totally works, but to make it neat, I need to create a few PCBs, get a video source, make a connector, rewire the whole thing.

But the result will be close to connecting a $40 media player to AUX input as somebody suggested a few posts above, control it from the remote - same video on the same screen.

I had a lot of fun and AHA-moments (as well as face palm moments) during the week of doing this and had to jump start my car like four times as the battery is old and I drained it... But as for working application - I can of course do all of this, but what's the point? The fun is no longer here Time to move on.

 

This is what was involved. Highly unsafe - there's always +12V from the battery present on this connector - could fry a lot of things. Lucky it didn't happen. I was not able to find what type of the connector is used too, I 3D printed v0.1 of my own and it can be used to replace the stock one with little modification. But again, there's no simple and easy solution on how to do this - you have to be able to program MCU, read schematics, solder, use testing equipment and have tons of luck. Or - enjoy smokes and probably fires as well as some bills to get the car moving again

Bummer; was hoping for something within my sphere of expertise.

But tell me exactly what are _you_ looking to achieve? (I'm hoping this can revitalize my interest )

 

Oh, just wanted to put in a new, better DVD player and keep the overhead RES screen.

That said, the screens in our 2002 & 2003 vans are pretty puny! If I actually get a better DVD player, it might behoove me to get a better rear screen setup, too.

So, again, why not a media player through AUX?

Dude, you are an electronics Jedi master! Very informative reading. Not that I understood it all but I got the gist. Looking forward to the rest!

 

Likewise!

You're right. It's absolutely non-intrusive, and for those items we don't finish viewing, just bring it up to the hotel room.

In my best Yoda voice (ahem), "Truly, an AV Jedi Master, you are".

Hahaha, I wish

 

Finally built a working hardware, found a nasty bug and fixed that, I think it's pretty solid for bypassing the video

Bumping an old thread, was there anymore progress on this?

 

I know this thread is pretty old so I understand if everyone has disappeared, but I bought a display from a junkyard with the intention of mounting it on my truck roof. I want to bypass all the Honda electronics and just use the output of the remote and the input of the screen running them through a separate computer (i.e raspberry pi). I'm having trouble finding information publicly about the wiring of the screen and boards. I'm wondering if you found a resource with some good digging, or if I should keep looking possibly reaching out to a Honda rep? I bought this today and through all this digging it was feeling impossible for a bit, then I figured out the wiring a little and it felt more possible, but this thread almost makes me feel like it will get done, at the very least thanks for the motivation boost.
