I've trying to listen to the audio from my iPAQ 5555 running Windows mobile 2003 with a Plantronics 2500 Bluetooth Headset. The problem is if I use the bluetooth functionality that comes with the iPAQ, it interferes with the WLAN function (as they come in on the same antenna). In speaking with the HP tech support, they recommended getting a Bluetooth PC Card for the expansion Pack Plus that I have. I tried getting the Ambicom Bluetooth CompactFlash Card with PC Card adapter, only to discover it won't support Headset audio. Please help!!!!! What I am trying to do is to listen to streaming internet radio with a Bluetooth device. Any suggetstions?
