Motorola HS801 Bluetooth Headset – Support Forum

Is there a fix in using hs801 with HP 6563 Ipaq [Motorola HS801 Bluetooth Headset - 112199]

The HS801 pairs with my Ipaq nicely but when the it is used coming out from a standby point. I can only hear the caller but they cant hear me. So what I do is play music via Media Player while driving or while waiting for a call so the hs801 wont be on standby. I think the problem is with my iPaq but I cant seem to find any solution. I have tried the handsfree device on other phones they all worked great.
