    Android steeringwheel control idea

    Hello. I'm a long time reader, first time poster.

    I'm about to buy a new car, and planning to use an android tablet as an headunit. As the car I am buying (mazda RX-8) have a oem steeringwheel control I want to find a way to use it to control the tablet.

    As I one day was playing with my phone I got an idea. The headphones I have has buttons for volume up/down pause, and if I doubleclick the pause it would skip a track.

    This got me thinking that it should not be too hard to build a little device that can translate the steeringwheel controls into theese same signals and enter them into the phone/tablet(only tried it on my galaxy note so far, not sure if it will work on all tablets)

    Have anyone done such a thing, and does the device I'm describing exists, or do it need to be custom built?

    I think the best way to do it is to use the ADK, however, I'm not a programmer, and don't even know where to start.

    this is a possibility since there are several steering wheel interface kits that use 3.5mm outputs to relay control signals, however you have to consider that not all phones or tablets will accept these remote signals and the interface kit would take up your audio output slot.

    here is a link to the interface kit manual: http://www.tacotunes.com/installation/aswc.pdf

    the other option is to mount a single DIN headunit as your amplifier either behind the tablet or in another location like a center console or glovebox and then use a steering wheel control interface with it, of course you will only be able to control volume and the reciever source but you will keep radio and cd as an option.

    the other main issues of using a tablet as a headunit are:
    • no AM/FM radio
    • no cd/dvd
    • extreme temperatures
    • power control issues

    If you can navigate your way past these or they dont bother you then you should be good. power control and hot summers were my biggest issues as the tablet will not charge when it detects high temperatures. Having a tablet that will boot on external power or finding a hack to have it boot on external power is the other biggest issue. otherwise you'll find your tablet dead and have to manually power it on every time you start your car.
