handfreekit in duramax communicate with stock radi

[bezerk]

Hello

 

Nice board you have here.

well, i just picked up the new daily driver, a 2003 duramax crewcab lt chevy.

i wanted to install the handsfree kit i have laying around (nokia), and was wondering if i can use the radio as well as the onstar microphone, to hook everything back up, so it will have the mute function, as well as the stock radio speakers (instead off the carkity one).

 

i am over in the netherlands, so onstar doesn't do a thing over here.

anybody knows how to do it, or has done it?

 

thanks
