  • 2003 Honda Accord Sports Coupe - a worklog


    Finally decided to create a worklog. I hope to cover my install history (been working on it for 1.5 years....), problems, solutions, etc. To set the stage, here were/are my goals for the project:

    When I Started -- these were my main goals:

    1. Have All my music in my car (48G) [Done!]
    2. GPS [Done!]
    3. cellphone integrated with system [Done!]

    Now, I have added more

    4. Traffic updates [0% there]
    5. Quick boot speed [???]
    6. Reliable [???]
    --Every Boot returns to the same state
    7. HD Radio [0% there]
    8. Auto-uupdates (weather, traffic , gas prices, etc.) via BT phone Connection [0% there]
    9. Voice Recognition/Control [50% there]
    -- Use Mode button on Steering Wheel to Pause Music && Enable MIC, with VC always on....
    10. Use as many of cars existing controls as possible.... [25% there]

    Compenents in car (right now):

    MB899 Intel Core Single/Duo Mini-Itx Motherboard 945GM with Intel Core 2 Duo Mobile 1.66GHz

    Other setup Info:
    My carputer is located in my trunk. It's mounted on a mdf board (with 2 rails, so I can remove the computer as necessary) which is screwed into the driver side wall of the trunk (there's a metal piece between the outside shell of the car and the fabric inside). I am using an Opus solutions case, which is to big to fit anywhere on the inside of the car.

    I have an amp under the passenger seat, my DSP processor under the driver seat, DVD drive/usb hub/DSP control unit in my center console,

    and USB UIRT/Car2PC behind monitor in the area that use to be the little cubby area (see next post for picture of monitor with the Parrot in the top left hand corner).

    Some post on my hardware setup. Up first -- touchscreen monitor. I have the Xenarc 700TSV as my monitor. I choose to place it in the little cubby below -- as removing the actual stereo would be VERY problematic for simpletons like me. I had this piece installed by a professional. He also made the piece the monitor sits in.

      Nice.. see my sig for my 07 accord coupe i had last year done.

      Talk to NeXson about a more OEM look for that xenarc.

        Hey John,

        Was looking at you setup and noticed your using a car2pc. Which buttons from the headunit actually work?

              If you get the radio attachment part from Honda for the 03 accord then that xenarc fits perfectly if you attach it from the back of that bezel attachment they sell... here is a pic of mine:

              Use the remote control of the xenarc instead of the buttons that are hidden behind the bezel.

                Goal: Integrate Phone with system

                Solution: Parrot CK3000.

                I had been waitng to see if either Streetdeck or Centrafuse would provide integrated software solutions, but after waiting (and waiting, and waiting) and reviewing issues with echo -- I just decided it was time to move on to a proven solution. So today, I got the Parrot installed.

                Given my setup, which removed the HU out of the loop, the CK3000 was installed after my amp and before the speakers. A relay was installed to shut down the amp when a call is active (some people want sound still working while on the phone -- I just want the call, I get so few anyways )

                Intial testing had very positive results. No echo problems and both parties heard the call load and clear (although the person in the car seemed to be far away).

                I went with the CK3000 as it fit where I wanted to place it (the others were to large) and I didn't need streaming music from my phone (aka CK6000).

                The Parrot is the device in the upper left hand corner of the picture in post #2 (it has the red and green lights....)

                After a couple of months of use the CK3000 was dropping calls and people were having trouble talking with me... So, I took back to Best Buy and had them look at it. At the end, I ended up with the CK3100 (they didn't have any more CK3000). The CK3100 does work/sound better and the interface is nice. But it doesn't look as nice and integrated with the setup as the CK3000. I will post updated pictures soon....

                  Goal: Voice Control

                  Begining Status:

                  SWIX connected to steering wheel which is read by a USB UIRT and translated into command via GIRDER. Prior to this weekend I had just volume and prev/next buttons workings. Over the weekend I added support for the mode button which when pressed sends PLAY && system MUTE (for mic) commands. This will allow me to leave voice command active all the time and just activate the mic when necessary.

                  To Do:

                  Over the weekend I had a Parrot CK3000 installed. It has a nice little microphone. I already had one installed -- so I plan to remove it. The mic from the Parrot has a standard plug, so I plan to get a Y slitter and use that one mic. Once that's done I will be able to program voice command and meet this goal.

                        I originally thought that I might be
                        able to get to it by removing the front bolts, loosening the rear bolts,
                        and leaning the seat back

                          Goal: Reliable

                          Over the 1 1/2 working on my system, I have gone through multiple pieces of hardware -- I am at the conclusion that most is not of high enough maturity or reliability to be mainstream... I hope this improves.

                          What has been reliable -- my memory module is the same one I started out with. My present motherboard and cpu have been going strong for the last 9 months (it took 3 iterations of mb/cpu combos to get to this point). Touchscreen has *worked* (once I figured out the correct settings) for a good year.

                          [12/04/06] Problem with no sound when audio clearly playing.
                          Resolution: Turn up the volume within Winamp....

                          [July 2, 08] Latest issue: Computer crashes at somewhat random timing. Testing today make me think it's related to the volume . I had the crash late yesterday afternoon (crash in this case = stuttering music, followed shortly by a blank screen (video still being produced as monitor light is solid) which I initally attributed to heat or power. I had it crash again, this morning --effectively limiting the idea of heat (it was a much cooler morning, and I had AC cooling the trunk). For whatever reason, I decided keeping the volume low could make a difference. Attempting that allowed the computer to run for the next 2 trips (about 25 && 45 minutes) without a crash. The next trip, I kept the volume low for about 35 minutes before raising the volume (much higher, but unsure what level I had raised it too) which led to a crash about 5 - 10 minutes later. Some further observations using SpeedFan, I noted that increasing the volume does increase the temps -- and no to slowly. Tested this at about 5am with outside temps around 70F, cpu temp starting at 121F. Raising the volume from 5 to 50 for about 10 minutes led to cpu around 126F. CPU is rated for temps from 0 to 100C, however, the MB is rated only upto 60C

                          [July 8, 08] Recurring Issue: Every so often (like this morning) my Opus 120W power supply will fail to power up as it's suppose too. It requires removing the power connector (maybe doing it a couple of times) and reconnecting it after a few moments to get it to start up again. This problem has been existing for a while now. I haven't noticed a pattern for when it works correctly vs when it fails to start. The problem has existed over multiple DC-DC adapters -- so I don't think it's that. But, if I assume that -- I'm not sure where I should be looking. I should note that I do have a valet switch that kills the 12V power to my computer.... However, it doesn't usually work. Well, the 12V is cut off -- but switching it back on doesn't mean the computer will restart. I have noticed this consistantly when I have had a computer freeze, that using the valet switch causes issues with trying to restart the computer. That said -- when my system does power up, power seems to work just fine

                          Other Issues I'm working:
                          - improve boot/shutdown speeds
                          - Fix my center console (doesn't open right)
                          - Make display more OEM[See post 28]
                          - Place the CK3100 in a better location
                          - Find ways to make usb mouse/keyboard wires retractable (or maybe a small bluetooth keyboard/mouse)
                          - fix broken aux cable
                          - add in a cable to recharge phone
                          - Configure my own rr skin to work with SN
                          -- need to use freq+/-, scan, tune, & surf radio commands
                          - my router doesn't reach my car...
                          - improving load times within RR (between different screens)
                          - determine wether power from usb powered hubs reaching back to my computer is a problem or not...

                            Goal: Utilize car controls

                            I had/have envisioned getting my steering wheel && stereo controls to work with my headless system. My first thought was to use SWIX for steering wheel control without much thought of the other controls. Then I learned of Car2PC, which I had hoped would give me *full* control. Well....

                            First off, just in case someone else out there is as dense as I am, I wanted to post what car2pc will do for you, using my 2003 accord as an example.
                            • Button
                            • AM/FM
                            • CDC
                            • Seek
                            • Repeat
                            • Random
                            • Tune
                            • Button 1
                            • Button 2
                            • Button 3
                            • Button 4
                            • Button 5
                            • Button 6
                            • Scan
                            • Volume Knob
                            • Steering Wheel Mode
                            • Steering Wheel Prev/Next
                            • Steering Wheel Volume
                            To help decipher if a button will work for you -- check to see if the button has actions the will apply to the CD Changer. Although car2pc says it will give you access to your steering wheel controls -- that is only true if the controls will change something with a CD Changer. That's why Volume control on the steering wheel won't work. The Mode button (switches between AM/FM/CD/CD Changer/etc) will only tell you when you enter/exit CD Changer mode.

                            Given the problems with using Car2PC for the steering wheel, I have implemented using the SWIX for that purpose (and it works, mostly). The SWIX works by sending IR commands to my USB-UIRT, which I then pass to Girder. The only problem I have with it, is the *responsiveness* isn't quite there. Especially the MODE button.

                            Once I got the SWIX working, I went back to get the Car2PC to do what it can. Well, that leads to my present problem. It turns out that both the usb-uirt and the car2pc use the same chip.... I have installed drivers for each individual device, but now only 1 will work at a given time. Specifically this is true if I use the Car2PC windows drivers. The non windows drivers do work with the UIRT, but not with the RR Car2PC drivers.

                              I can change volume on my steering wheel, from any mode.
                              And no problem with button functionality at all.
