    2007 Honda Odyssey with Factory Navigation

    I have a 2007 Honda Odyssey with factory navigation, back up camera and a DVD player in the center row. My goal is to install a computer while maintaining full functionality of my factory components. I also intent to use the stock navigation screen to interface with the PC. This screen comes with a touch-screen feature. Below is a picture of the dashboard and the screen.

    One of the biggest challenges was to find a way to convert the VGA signal coming out of the computer and feed it to the factory screen, which uses RGB signal. A bigger challenge was to find a way to use the factory touch screen feature and use it with the PC. After lots of web surfing, I found two methods to accomplish these tasks.

    The first method involves disassembling the screen, cutting some wires and building some basic circuits. It also involves using a special device to convert the VGA signal to RGB. Here is the link that shows the details on how this method works. http://tl.acurazine.com/forums/showthread.php?t=606261.

    The second method consists of a “black box” called GA-Net+ that interfaces with the factory screen and allows you to convert the VGA signal to RGB and use the touch screen feature. The VGA signal is actually modified within the computer by tweaking the screen resolution so that it is visible in the factory screen. The GA-Net+ is plug and play. All the connections are made through the factory navigation computer. There is no need for disassembling, wire cutting, circuit building or installing extra equipment. Here is the link that shows the schematic of how this box works. http://tl.acurazine.com/forums/pictu...ictureid=23881.

    After comparing both options, it is obvious that the second choice is the easiest and less painful. By not opening any of the factory components, the warranty is not voided. One thing to keep in mind is that this box only works with some motherboards. In general, it only works with boards that allow a screen resolution of 840 x 480, 60 Hertz, interlaced. This is a type of resolution that is very rarely used in the computer world, and hence; there are very few boards that support it.

    The sound is easily integrated through the auxiliary sound port. Here is a schematic of the project:



    Here is the list of components that I used for my project:

    Motherboard: ZOTAC GF8200 – C- E: http://www.zotacusa.com/zotac-gf8200...therboard.html.

    Processor: Sempron LE-1300, 2.3Ghz, 64 bits, AM2 socket: http:www.AMD.com.

    Memory: 2 x 2GB DDR2, Rendition: http://www.rendition.com.

    Power Supply: DC to DC, M2-ATX, 160 Watts: http://www.mini-box.com/M2-ATX-160w-...8&category=981

    Hard Disk: Seagate EE 25.2, 60 Gigabytes, automotive grade: http://www.seagate.com

    Interface Unit: GA-Net+ (see URL link above.)

    Front End Software: Centrafuse 3.1, with customized Honda logo screen: http://www.centrafuse.com.

    Navigation Software: Garmin Mobile PC, embedded to CF: https://buy.garmin.com/shop/shop.do?cID=139&pID=13484.

    Here are some pictures assembling the PC:






    Now some pictures connecting the GA-Net+ to the factory navigation computer:





    Here are the pictures of the project after completion.






    As you can see from the last picture, I installed two remote USB ports. The GA-Net+ comes with the Map/Guide button pre-programmed to toggle back and forth between the factory stock and computer mode. Other buttons can be programmed to perform certain task as well. For example, the joystick is programmed to simulate cursor movement. An upward/downward push of the joystick causes the cursor to move in the corresponding direction. A center push of the joystick simulates a left mouse click.

    Here is a video of my project in action

    I like that. Nice and subtle and looks part of the dashboard. I just did my jeep and uploaded the project here yesterday as well.

    Where is it exactly? Did you paint the case? Does it impede the seats moving/reclining in anyway?

    Your setup looks amazing and is exactly like I would like to do for my 2007 tl navi! Would you be able to provide more information on how you interfaced the GA-Net module with the existing navigation system. There is very little information regaring the GA-Net module setup/installation online. Any help you could provide would be greatly appreciated!

    luddygt,

    Welcome to the forum and thanks for your comments. If you want to know more details about the GA-Net+, send me a PM. This unit works as advertise and it will definitely work in your Acura.

    Thanks again,

    Very nice install.
    Can you please tell me how you integrated GMPC into CF ? I can't find a guide for doing so, that works...

    TIA, Per.

    i love your install! i'm definitely considering this method for my 07 TL.
    How do you like the color and text quality of the screen compared to a lilliput/xenarc?
    How much did you pay for your GA-NET+ ? and did you get it from fluxmedia or the russian guy?
