Passenger Talk for XRT

[XRTPalisade]

Hello to all,

Glad to have found a Palisade specific forum. My wife and I purchases a '23 XRT Palisade last and she was excited to use the passenger talk feature only to find out its not on the XRT model. I can see the passenger talk function works on the screen but no audio in rear seats. Does anyone know if its just a matter of adding rear speakers for passenger talk and if the wiring already exist in the rear?

Thanks
Jose
