2004 Accord navigation with carPC

Hey Blazer563, I don't want to divert the topic at hand. I get excited every time there is a new post here. I've planned on posting a thread of my install when I'm done (if it works

). I've sent you a PM asking for your email address so I can email you my AH20 photos built with the AngryCamel DIY kit.
As for the touchscreen, I'm awaiting results from this forum. Honestly, I would do the met152 trick if I could, but my Accord's NAVI touchscreen doesn't have the obvious 4 wire control. I contacted Sharp (the maker of my OEM touchscreen) to get the wiring diagram and they said that it is was built proprietary for Honda and they have no info on it. He also mentioned that Honda would also be very unlikely to share details as this is their prorprietary info.
I would love to build a passthrough harness similar to the AH20 for my naviscreen so I can play around and figure it out. I saw a guy on another forum fry his system while 'playing' so I'm a bit hesitant.

Work done so far..
- Wiring power from battery to trunk with 10guage and fuse done. NOT near as bad as I thought. My wire routing was different than AC's Acura but the same generally. Accord Automatic - Driver's side firewall grommet. Accord Manual - Passenger side firewall grommet. I had the automatic.
- Wires from trunk to center console done (but I forgot one so now I have to remove the back seat again.. damn).
- AH20 video harness done
- I've got the DIY C Connector harness from AngryCamel also, but I'm going to wait for the module that I can splice into it before I put it together. Note to AC: I want something I can splice into this puppy! Solve the problem already! ;-)
- Scan do 800.. mine was fried.. waiting for a replacement.
- Car2PC.. STILL having issues but they are still working with me. They are sending me a chip that will capture all IEBus packets. For some reason, something on my IEBus is telling WinAmp and MediaPlayer to STOP playing music whenever I start playing music. Sent them log info to diagnose.
- Disasembled and Reassembled the dash too many times now. Those little spring clips.. they fly pretty far. Where can one buy extras?
- No interior/exterior blemishes yet from my futzing.. but i can use some extra spring clips.
- Still having fun!

Hey again.. I realized this is a different thread just now. Haha. Too many threads in my head. I'm watching AngryCamel's thread on touchscreen control and had it mixed up with this one. Still though.. send me your email and I'll email you the photos.. I'm not yet ready to post my total install.. still a ways to go.

Which scan converter did you get by the way?

If for whatever reasons it is not possible to get the factory touch screen to do work on a carPC, my next guess is going to be to get a touch screen panel and lay it on top of the factory one. I know it's easier said than done but, I can live without the factory touch screen working. But it is easy to have the same switch that switches the monitor from nav to carPC disable the PC touchscreen. I was unable to get the nav sys out before my car was taken to a mechanic shop.

Hey ashtray what is the tvandnav2go going to be used for? Is that necessary or just something you want? If i remember correctly you mentioned that before.

Also you can get the clips that you say are getting loose at home depot or lowes. Just goto the hardware department where there is different screws and bolt. Look for a sign that reads: hard to find parts or something like that.

Just an off the topic tip: always use Honda factory parts of you will end up paying more later.

Til next time...

any updates on this?

Yes, updates..

I didn't write my second entry yet. I gave up on my hopes of controlling the touchscreen. I still have no idea how it is controlled even after dissecting the NAVI screen and staring closely and intently. The actual screen does not appear to have the tiny dots associated with resistive touchscreens. I've got tons of photos if we have any touchscreen experts.
I went with my plan B and flush mounted a small USB "Ergonomic Touchpad" from http://www.ergonomictouchpad.com/ into the dash

Wow, very cool; good writeup too. Cant wait for the audio and other parts!

That's not the only way to get video, right? Couldn't you intercept the video cable where it plugs into the unit instead of cutting wires in the trunk? I imagine you would need a specialized interface cable. Cutting wires makes me nervous about permanently messing up my car.

No, thats not the only way to get video. Here are some easier ways:

Thing is, I believe all of these are S3 or composite inputs which would be great for hooking up your DVD player. These devices then take that signal and convert it to RGBS. But to take computer resolution and down it to S3 or composite, just to have the device then take it to RGBS, many people say its too fuzzy. I didn't risk it and did the VGA to RGBS conversion with a scan converter.

BTW.. I fried my scan converter during the wiring process. In the pictures, the scan converter is powered by a power supply plugged into the wall. When I had it working on the car power supply, it was getting lines scrolling because, I learned, it was on the same phase as the laptop power supply. So, I was dorking around and I can't even remember what exactly I did but it caused the magic smoke to exit the scan converter (it will be my 3rd). Looking for a new one on eBAY but the only ones I can find are way over $400. I'm patient though so I'll be waiting for another one at $40.
