For voice recognition we need a microphone :
I have used Logitech's USB version with the mic mounted at the front ceiling and its AD converter board stored away above the fuse box and behind the push button (not installed in the picture- you can see a hole though). You can also see the ACC wire and M1 signal lead sticking out:
The same arrangement on the passenger side allows for adding a 4-port USB hub which connects the Holux GPS receiver, and a 802.11b stick. It's also proven useful for connecting a keyboard when BIOS settings need to be changed :
That's about it for show & tell; maybe a few more details and plans for the future: my goal was having a customizable voice recognition GPS system. During operation I have Google Earth and CoPilot 10 running. One for guidance, one for looks. Voice recognition is done by Responding Heads plus a couple of AutoIt scripts. This works very well at <55MPH but refuses to listen when going faster. Networking is provided by Boingo and an Ashton WLAN stick. Unfortunately the Ashton drivers are crap and occasionally fail to resume from hibernate. I am hoping that devcon will fix this. The on-screen keyboard software I use is amazing- but I can't for the life of me remember its name. Just search the forum for a previous post by me linking to it. An OBD2 USB interface is already installed - I just have to write the software for a realtime MPG output.
Total project time: ~3 months.
a) get a GPS antenna and hide the GPS module inside the dash. Currently it has to rest on top of it to get a signal.
b) build a PCB to interface the garage door opener via serial port and add an "Open Sesame" command to Responding Heads
