Bluetooth module for Arduino from headset

I have Plantronics bluetooth headset. On the card of the headset I have see RX and TX out. And I have question : I can use this headphone for Arduino as Bluetooth module ? and how it will affect on the Arduino ?

Link?

I miss model of headset, but there is photos of chip :

It looks like it has a set of SPI connections too. I can't say what you could do with it though.

If I simple connect Arduino with RX and TX to this headset. And try this code (with small corrections) : http://iteadstudio.com/produce/play-bluetooth-with-arduino/
What I will have ?

More information than you have now.

And what about Arduino "fry" ?

You should find all the information you can on the headset before you attach it to the Arduino. Things like is it true serial output or TTL serial output. Baud rate, start bits, parity. etc. are needed, to.

Ooh. OK. But I will need some bootloader on the chip from headphone or I can connect Arduino to bypass ? I mean, I can stay with old chip and connect Arduino ?
