BB 8350 Bluetooth problem with PTT
 

Hi, I have a BB 8350 wich has the PTT (Push To Talk) function, which I use a lot. When I connect my BB with my car with Bluetooth, it works perfectly on every aspect, except the PTT function.

If I make o receive a call via PTT, the music in my car will keep on playing, as if the car did´nt recognize the call. Furthermore, if I want to use the PTT "normally" using the BB, it wont make any sound. I can´t listen a thing in my car (with bluetooth) nor the phone. Plus, the caller won´t listen anything either...

Any ideas???
Please help me!!!!!

software design, no fix
 

When I had this phone it was a hot topic and the official response from Sprint/Nextel was that this was purposely done to keep cover in surveillance situations. Lame if you ask me because headsets blink brightly anyway...
