It depends on the hardware, phone/device, BT version etc. I've been using A2DP for years and own half a dozen BT stereo headsets. I used to have a Motorola handsfree bluetooth device for the car that had a built-in FM transmitter and played A2DP. That thing worked great!SnowItch said:You are correct. It would be great, but to be honest, the implementations I've used of stereo blue tooth have many issues. I'm sure that went into the decision not to support it.
