I'd like to connect my Treo 755p to a wired audio system with a headset, but I need a way for the Treo to accept a seperate mic input. Is there any cables out there that will output stereo audio and has a seperate 2 pin mic input jack? I've looked everywhere but nothing seems to exist. The stock headphones that come with the Treo will do stereo out and has a microphone so there should be a way.
