    My WRX CarPC plan (feedback?)

    Hey everyone -

    So here's my plan for my WRX CarPC. Anyone have any suggestions?

    Gateway M405 laptop (already have) $0
    Carnetix P2140 $135
    Lilliput 619 or 629GL $251
    WRX bolt in double din kit $130
    BU-353 GPS receiver $69.99

    RoadRunner/IGuidance $99.99
    OR
    StreetDeck $199.99

    existing alpine HU (relocate to factory clock position)

    If the audio on the laptop isn't up to snuff, I'll go with a better USB audio card.

    I'm planning to mount the power supply behind the dash with wires up to the battery and the laptop under the passenger's seat. I'll set up the laptop to power on with car power and then to standby on car power off (either through USB or ASCPI wired to the laptop power button) and then hard power off after 2 hours of car power off. Audio out will go to the audio input on my existing alpine HU -- at some point I may swap it out for an amp.

    Thanks in advance for any feedback!

    -Justin

    Looks like you've got a good plan.

    If you haven't already done so, i'd make 100% certain that the power required by the laptop is capable of being put out by the Carnetix unit.
    It probably is, but there are some makes/models of laptops that use some unusual voltages or multiple voltages that make a Carnetix unit useless.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    Great, thanks for the suggestion. The laptop takes 19VDC on a simple (barrel type?) probe, so I'm pretty sure I'm set there. I also found a docking station for it for dirt cheap so that might help (although it doesn't have a power switch which would be very nice).

    If you're thinking of relocating the HU up to the clock location, you may already know about this little gem, but just in case:

    CarPC v2.5 up and running - all hardware installed, skin configured, and iG tweaked like crazy. Now for OBD-II, and voice control, and camera plugin, and... :nutz: - it never ends!

    Just get a car adapter for the laptop and save 100 dollars.

    Also, if you get the bu-353 (proper name?) it comes with a magnetic base, which you can stick to the top of the head unit and it still fits underneath the OEM gauge hood. This puts it in a great place for GPS reception; raised, invisible, and in the center of the dash.

    Wow, great suggestion on the GPS location. I'll definitely give that a try.

    I'm still going to go with the DC-DC regulator as I want to have the laptop go to hibernate gracefully when the car power turns off and come back on with the car power. The first half I can do with an inverter or car PS, but not the second. Also I'll get consistent power during engine crank, etc with the regulator.
