OK here's the page it can be done!!!
i know somebody out there can do this!!!
in my SUV i have a stock usb port that is for an ipod or if u have MP3's on a thumbdrive you can plug that into there and the stock radio reads it.... cool i know!!! anyways for ipod wise the stock radio also controls the ipod if i hit track forward or back or what ever it sends a signal to the ipod to do those functions(standard I know). well my idea is this. have some type of software or emulator that makes the stock radio see your carputer as an IPOD. so that when it I hit pause,track forward, play or what ever it sends a keystroke to the computer, that i then can tel Centrafuse or what ever front end u guys use that this keystroke corresponds this function on the frontend. Now for the harder part, of my question. can we get audio to run threw the USB as well. Then we have True Digital audio going to our stock radio's. And no i am not looking at the CAR2PC device that isn't gonna work for this setup. just a strait male to male usb cable one from the computer to the stock USB port on the radio.
