    My Volvo XC60 Andoid project (finished!!!)

    Well,

    I bought my Volvo XC60 without navigator, basically because I don't want to pay 3000 euros for a limited, closed and 2D navi.

    I bought this tablet:
    . Viewsonic Viewpad 7". capacitive 7" screen, 3G, WiFi, BT, G-sensor, multimedia, etc.

    I have internet (through iPhone tethering), OBD-II (through BT), an inclinometer, On-road and Off-road navigators, etc, etc, etc.

    I tried some front ends, but I think Android is friendly enough. This is my first screen:



    All works good: the multimedia, navigators, menus, ...even, if I like the radio music, I can see author with Soundhound.
    The tablet is connected to cigarette supply through USB (5V/2A), and to AUX input in car audio.

    I also installed "noBlock" app to avoid blocked screen, and Softkeys app to use the classical four Android buttons with the touch. (I cannot use the hard buttons)

    The tablet can stand up to 100 hours in "stand-by mode", and it starts autocatically when it detects external supply. When I stop the car, the tablet puts in a low battery mode. The Tasker application do it very well. But, if the car remains stopped more than 100 hours, the tablet shutdowns definitely and pressing the ON button is required to start it again.

    And this is the "only" problem: I can't access the ON/OFF button because it is in the lateral side.

    To understand the situation, here is my last project (a WinCE chinese GPS that breaks at few days)




    So, I have two solutions:
    - Assume I must disarm the car to push ON button when I return from holidays
    - Extract the ON button (wiring two cables or any mechanical solution)

    Any other solution/recommendation/idea?

    Thanks!

    i have a similar problem with my dell streak 7 which has even worse standby time and will drain overnight even in airplane mode with the screen off.

    here's my idea, pick up a smart DC-DC powersupply with a conffigurable low voltage shutdown and wire it to a constant 12v supply, trigger your standby using your headphone connection to your audio source. that way you keep your unit charged without ignition and still protect your battery. not sure how long it would extend the standby life but it couldn't hurt.

    only other idea would be to find a power supply with a auto boot on ignition signal and hard wire it to the tablet.

    I only need to push ON/OFF button once or twice a year (or if it hangs), so I will extract the ON/OFF button.
    I fear solding in a tablet, so I probably will look for a mechanical solution, like trigger cables in old reflex cameras.

    Yes, I use an Viewsonic Viewpad 7", with Android 2.2. I think Galaxy Tab is better, but I have space limitations.

    Addicional hardware:
    . ODB2 sensor (from www.dealextreme.com, the blue one) with Bluetooth
    . 5V/2A car charger (important 2A), wired to USB
    . audio cable to car AUX input,

    Soft:
    . Tasker, to automatize start/stop procedures
    . NoBlock to avoid Android block screen (not necessary in your car)
    . Softkeys, because I don't have access to hard buttons
    . Torque or DaskCommand for OBD2 car info. (DashCommand is too slow)
    . GPS navigators: Google navigator (needs internet) and Sygic (no needs)
    . PowerAMP music player (there are a lot of players)
    . Soundhound, to identify radio music
    . etc, etc

    I have internet through iPhone tethering.

    The look is the standard Android user interface with some widgets (Poweramp and wether)
    There are some frontends, but I think the standard interface is good enough.

    Good luck!

    Thank you for the info. Is the app running in the pic torque? Or is it dashcommand? Looks totally different than what I've seen on my ipad.

    No, the 2nd image is an old project in WinCE. I don't remember what is was, but neither DashC nor torque. I just put to understand the ON button unaccessibility.

    do they make a CAR CIGARETTE charger for the viewsonic? I believe if my galaxy tab goes all the way dead the car charger will power it on by itself.

    Well, more problems.

    I've thought a 5V/2A output car charger would be enough to juice the tablet, but the charge is still slower than consuming.

    So, in a few days, the tablet will die and will need to be restarted.

    A 5V/2A wall charger works good, but a car charger with the same output is much slower. What's the difference between them?

    I'm desperate.

    You need to check if the high-current charge is available with something special like : d+/d- short , special connector with extra pins etc
    Some devices need "special" notice from the charger when connecting to a power supply ( otherwise the tablet might just limit the current to 500ma )
    HeadUnit : Car-Pc | Processor : JBL MS-8 | Front Stage : Woofer - Mpyre 65M , Mid - Dayton RS100-4 , Tweeter - Tang-Band Ceramic 25-1719S | Subwoofer : Hertz HX250D | Amps : A/D/S PQ10 , Hifonics Olympus XI , SPL AB03445 | Wiring : Sommer , Neutrik
