that was good that you got the video interface , and now your problem is the audio, easy go to ebay .com and look for pyle fm modulator from that you can hook the rca audio line and transfer it to your radio in your carthru the antennae or use the aux input from the dash, when i intall my roof dvd i also bought fm modulator but at the time of installing them i just figure out that i dont need the modulator what i did i run the rca jack from audio output of dvd and the other end plug in thu the aux jack of my RL i also have navi so inthis case this should also work on your RL
