    WRX Wagon - Where to start?

    So, this is what I have..

    1 - Laptop - Toshiba A75, P4, 512MB RAM, 80GB HDD, USB, WiFi, and lots of heat.
    2 - Screen - Lilliput 619GL-70NP/C/T 7" VGA, picked up used and in the mail
    3 - Carnetix 1900 V2
    4 - Roadrunner downloaded

    Thats basically it right? Besides cabling, software and fitment.


    Step 1 - Laptop is wiped and a fresh install of WinXP is on there. Yet have to strip it down somehow to run a little better, then fiddle with roadrunner.

    Step 2 - Watching some spare power supply's for the laptop on ebay right now so I can hack off the plug to fit the carnetix. Still need to verify how that all works with the touchscreen and laptop.

    Step 3 - Need some sort of wiring schematic to work out what goes where. I have basic locations for where in the car it will go, and a rough idea how to run the wires, just need to put it down on paper.

    Step 4 - Bench test? Think I should probably get it all together on the bench before tearing the wagon apart. I have a 12v supply, should not be too hard..

    Step 5 - Install..



    So, any hints or tips? decent lessons learned? I have been reading the forums for a few weeks, taken notes on the other WRX installs, and besides the software tweaking it doesnt look TOO hard (famous last words).

    What year wagon do you have? Have you thought about the screen placement yet?

    Its an 02 wagon.. screen will go in the double DIN spot..



    Need to sort out the HU though. I think it will end up in the glovebox until it all is sorted.

    Glad to hear you're ready to get the ball rolling

    Where do you plan on mounting the laptop? That will determine how some things are wired up. I haven't used any Carnetix products so I'm not sure how it would be configured, but I don't imagine it being much different to any other car PC power supply. Usually, there's a 12+ line which goes to the battery and it should be fused. Then there's the 12- which should go to a ground point near the power supply. Then there's an ignition line which would be hooked up to your ignition circuit or accessory circuit - you can tap into the existing line from your car radio wiring harness. Then there's probably a turn-on wire from the power supply which connects to the car PC motherboard, or in your case, the on-off switch of the laptop.

    Does your headunit have auxiliary input? If so, you could mount the headunit in the glovebox and connect the audio output of the laptop to the aux in of the headunit. You'll save money because you won't need to buy an amplifier (but you can still buy an amplifier if that's part of your plan).

    Mount will be similar to a fellow wagon owner in the trunk. There is a tray under the floor but above the spare. No problems..



    Data+sound wires down the drivers side or the middle, and power down the passenger side.

    The power supply shouldnt be hard to wire up, I have an old power supply I can hack the plug off the end.. But I do need to work out the on/off controls. I dont want to hack into the laptop if I dont have to.

    HU Does have a Aux in, and it will live in the glovebox until everything is working well and tested over a few months. Then I may take off the faceplate and mount it elsewhere.


    Right now I am having problems figuring out how to lighten up the WinXP setup. Just finding FAQ's and tutorials on nLite and other alternatives.

    If you're using nLite, you may get some guidance from this article on building an XP boot disk for an EeePC netbook.

    You might also review this article from ExtremeTech on reducing XP boot times.

    Some techies recommend eliminating System Restore, but I prefer to keep it. I like to reduce the disk space it uses to about 1GB (Control Panel > System > System Restore). I also like to reduce the Recycle Bin to about 1GB (right-click the Recycle Bin, > Properties)
    .
    If just enough is really good, then too much ought to be perfect.

    Well this last evening/night I gave up on nLite. The biggest reason was that the DVD that has XP on it that came with the laptop is an image one, so it has all the toshiba software and drivers merged into one. So nLite wont recognise it to build from. So I would have to use a different XP disk, merge the drivers in myself, then see if the CD Key will work as the only other XP Disk I have is used for my home PC.. So, thats out the window. I did however disable/uninstall a ton of stuff, and will review those articles today.. thanks

    Also messed with the hibernation features. I was really hoping not to open up the laptop to install the W3bMa5t3r module thing.. but it looks like I may have too.
