You didn't need the adapter unless you have the 4.3" screen - the 8.4 has a direct composite video input on 3 pins of the TGM.

I thought so too, but without the adapter, the camera doesn't activate in reverse.

just went thru the process a few weeks ago, my journey wasn't prewired, had to run an RCA and buy this adapter http://www.navtool.com/2011-2018-dodge-journey-video-interface.aspx
