I am able to operate the voice control feature on my Ipod Touch 3g with the included headphones with microphone. However, I am not able to use the voice control feature with a different microphone I have with a 3.5 plug. My goal is to be able to operate my Ipod touch with the voice control while driving. I do not like leaving the headphones dangling out of the jack in the car. I purchased an RCA input cable for my Pioneer car stereo. I am going to purchase a cable that goes from the Ipod dock connector to RCA for my music output. I am hoping to find a microphone which will work in the 3.5 jack to use the voice control feature. In my manual it says the voice control "Requires included headset or compatible accessory with microphone." What is a compatible accessory with microphone? I have googled a lot and haven't found any options other than headsets with a microphone. Are there not any other options out on the market yet? I really like the potential of operating the Ipod with voice commands while driving, however, I haven't figured out how it would work yet. I am open to any input, so please respond if you have heard of any options Thank you !
