I'm starting my conversion to a Android setup. Did tons of research. My tablet has AndroI stilld 4.0, soon to be Android 4. 1. YWonder ou wcan ant to make sure it has Android 3.0 and up. These versions support USB Host Mode. Which allows you to connect tons of devices.
1) For phone/text: Tablet Talk. Connects via BT or Wifi. I wanted to use Wifi mode, but when I started this post, I realized that when connected to 3G/4G, Wifi turns off. *Note, due to Android limitations, you have to use a BT headset posted with phone, not tablet. Since I want to use this in my car, through speakers, the Car PC will act as a kind of emulator via its BT, mic and speaker.
2) For GPS: tetherGPS . Also connects via BT or Wifi. I needed this because my tablet came with everything underneath the sun, but GPS.
3) For OBD2: Torque Pro (must be pro version to use USB) via USB OBD2. Tablet or phone must be Android 3.0 and up, and must have USB Host Mode in debugging section.
4) TPMS: via BT. I think they may have a Wifi mode, didn't check though since it would be only device tying up BT. Also with Android 4.0 and BT 2.1, you can connect more than one device. Anyways, the app is called TireHawk Bright+. The app is in the market. It's full version, but in demo mode. Once it detects the TireHawk unit, it will switch from demo to real. Still waiting on pricing from company. Seems to be the only Android TPMS solution. What really attracted me is that the sensors mount on the valve stems ( has anti theft feature also). So easy to install. Also has replaceable batteries.
That's what I got so far. Most everything else is available in Google Play Store.
PS: i still have my Car PC. I use it to store all media, tether 3G/4G/wifi connection to create hotspot, convert tablet audio to 7.1, create BT headset emulator. Also controls all screens, amps, and inverter.
As far as voice recognition, I can see if my BT headset idea works. I don't think it will since that is tethered to phone. Wonder if I can pair to 2 devices. Tablet and Phone via PC? I'll let you know.
Found this article, so may hold promise. I guess I have to see if BlueSoliel has the ability. HMMM, I'm going to uninstall BlueSoliel, Windows does PC speakerphone natively as far as paired to one device. If not, something on PC will. http://reviews.cnet.com/2719-7609_7-295-2.html
