Has anyone found a solution that allows one to fully interface the Treo 800w with a 2005 Nissan's audio controls? Specifically, I'd like to know if there's a way to not just get the audio, but be able to use the steering wheel-mounted controls to changes tracks, etc? I have a 2005 Nissan Titan and, while there is a RIM BT device that would allow me to hear the audio through my car's stereo, it would be even nicer to have use of the steering wheel buttons for switching tracks. I found something that might do the trick here: http://www.oemautosound.com/pc-185-1...ly-030405.aspx but I don't think the WM6 media play would accept the track up and down commands, or would it?
