Just in case anyone is interested...the Parrot CK3100 works perfectly. I had it installed in the "cubby-hole" space just below the DVD slot.
The voice recognition is awesome - no buttons to push! I just say "phone" and then the name I wish it to dial - it mutes the stereo/XM/CD automatically and then dials! It also mutes the voice on the navi (when it is giving directions) so it does not interfere with the call as well. No problems with the voice commands/recognition on the navi either.
Definitely the way to go...(but then I didn't like using the headset in the car...even with the volume up, the clarity just wasn't there...and my battery would usually die

...)
(and no, I do not work for Parrot

).
