Infiniti G37x without navi and backup camera

[m4gnum]

Hello.
I just bought a 2009 Infiniti G37x sedan, I hope its going to give me as much happiness as my previous 2004 G35x did. Its got the Bose premium sound, rca plugs and a screen but it does not have navi, sensors or backup camera. I would want to have the rear view camera and navigation or a phone screen mirroring so I could use the phone navi. It would be also great if I could play music using bluetooth. What is the easiest way to make it work without spending much money? Maybe there is something wireless?
