I am using a new T-Mobile MDA running Windows Mobile 5.0 together with a Jabra 250v. I tried both the original BTToggle (which required that I upgrade to .NET CF 2.0) as well as the BTToggle_PPC.ARM (which I installed only after uninstalling the original BTToggle and .NET CF 2.0). Neither of these have worked for me. The messages appear showing "Voice Speed Dial On" and "Audio Gateway On." But at no point am I able to hear the Media Player in my Jabra Bluetooth headset; it simply continues to function as a handsfree for VoiceDialing and Cell Phone only. Have I forgotten something in the setup process?
