You can add it. It is a module with a stick on microphone. You will have to find out if the 2009 is a High Speed Bus or Low Speed in order for it to work. You are lucky with the old style radio. Remove the radio and unplug the big gray connector. Plug the harness that comes with the kit into the radio. Then plug the harness that was in the radio into the new harness. Done. Run the microphone wire and stick the microphone wherever you want. The directions may say by the driver, but I put mine in the middle of my Nitro. I do not know where the module mounts on the DJ.
