echo cancellation

[RoByX]

Hi,
in a t10 with 3.06EU firmware it's possible to activate the "echo cancellation" when it used with a bluetooth cell phone in handsfree mode?
the headphone out of the t10 is connected by 3,5"jack to the line in of my car audio system.
Yes, the t10 bluetooth's handsfree function is designed to use it with a hearphone so the dsp "echo cancellation" function is no needed but i use it with the car loudspeakers.
Sorry for my english
Regards,
RoByX
