When i get a call in my camry it goes thru the speakers. I am afraid I'll get a call and my wife will be with me in the car, so she will hear everything being said. I don't know how to switch the call back to my cell phone for a private call. I tryed a few times and just lost the call. Anyone know how this works

If you have the NAV Bluetooth implementation there is a "Send" button on the screen during the call to send the call audio back to the phone. I don't know if there is an equivalent in the Non-NAV Bluetooth.
Regardless, your phone should have an option to take the audio back from the handsfree device (the Camry is a handsfree device as far as the phone is concerned) during a call but that would be phone dependent on how to do that.

I don't have nav on the camry, but thanks for your reply

Can't you politely tell the party to hold a sec. Pull over. Ask the wife to step out of the car a sec. Then continue the coversation?

Or break off the relationship with the mistress?

I was thinking more along the the lines of "the bookie".

On my Treo 700p, it's only a couple of button pushes to disable bluetooth. Just do that as you're getting in the car and problem solved.
