Headphone jack takes priority over Bluetooth for phone audio?

[ablatt]

I just started using a BlackBerry Curve 8320 with Rogers a few weeks ago.

I plug a cassette car adapter into the audio jack on the Curve to play mp3s in the car using the BB's Media Player since my 2003 model car doesn't have an audio jack or bluetooth.

I also have the phone connected via bluetooth to a Jabra SP700 car speakerphone.

Each device works well on its own, but if I am playing audio through the phone's headset jack I won't hear any audio if a phone call comes through over the Jabra using bluetooth unless I disconnect the car cassette adapter from the headphone jack on the Curve.

Is there no way to set an option that allows Bluetooth phone calls to have priority over the headphone jack and route phone audio to the Jabra even when the headphone jack is being used?

That's how it works. If you have something plugged into the headphone jack, then the Bluetooth audio will be disabled. There's no work around.
