I want to add a DVD player on the cheap. I already have JVC kd-avx2, which is probably overkill for the application but I already own it so why not? I wish to install this in the single din opening under the factory radio. Other than the Aux plug in the console, is there an easy way to feed just the audio into the existing system? Where is the best spot to grab power from for this endeavor? (I do realize I won't have any video to the MFD, I am just looking to feed the sound in) Thanks!
