Default BT headset doesn't trigger headset profile?

Hi all,

I have a audiovox smt5600 and when i had WM5 installed, I noticed that my BT headset would trigger the headset profile. When i flashed back to WM2003, I found that this no longer worked (however plugging in a wired headset would work).

Does anyone know how I can get a BT headset to trigger the headset profile ala WM5? Any workarounds?

TIA
