ABOUT THE ORIGINAL MONITORING MODULE

Greetings to friends. I bought 2006 407. I want to add aux usb and bluetooth feature without changing the original tape of the car. Bluetooth is very important, especially since I use spotify. There is a bluetooth option in the menu tab, but it does not take any action. I do not think DOUBLE screen etc. I want the car to remain original. Is there any solution suggestion, how should I proceed? I would be glad if you help.
