Adding Bluetooth to 2005 Super V8

Greetings,
I have a 2005 Super V8. It has the DVD player with monitors in the headrests as well as Navigation. It does not however have Bluetooth. Does anyone know what modules/cables are needed to add Bluetooth/voice to my existing system? Also, would the module(s) be mounted in the dashboard or in the luggage compartment with the DVD player, Navigation, and CD changer equipment? Searching online for information has left me confused by conflicting information and my local dealership isn’t real sure about what parts are needed to accomplish this addition.

Any information would be appreciated.

Thank you,

Mark Kosisko
