So my Pioneer car stereo has a built in usb port. It has the ability to play my ipod touch or iphone through the stereo. What about the captivate? I have set it to everything imaginable. I thought Mass Storage would work best. I haven't tested this since I upgraded my phone to di11i v5.4, as there is nothing but snow and ice outside, so no need to be in my truck. Do you guys think the upgrade will allow it to be a usb media player?
