Touch Pro In Call Through Car Speakers

[pacerx]

I was wondering if anyone knew of a way to get the touch pro to use the car speakers through the stereo out and use the built in microphone and/or speakerphone capability to talk in calls without it having such terrible echo.

Currently if i simply plug in my car's speakers and make a call, I have to mute my end every time I stop talking or it will echo like crazy when the person on the other end starts talking, which kind of defeats the purpose of 'hands free'.

Is there an application that will take care of the echo in this situation? or must I buy a radio with bluetooth capabilities and mount a microphone in the car?

Thanks!

Anyone have any ideas?
