[RS250R]

Basically you direct your player output into the AUX Input. The plugin can be seen on your dash. You would however tap into (splice) the wires behind the dash. Easy enough and requires little effort, however there is a drawback. Most folks have to use a line-level amplifier to raise the output from the player to an acceptable level so they do not have to crank the head-unit volume way up for good sound.

This means extra cost for the Line-Level Amp. Also, the AUX channel does not drive the IR transmitters that are on your rear seat controls. Not necessarily the end of the world since the Myron&Davis monitor has it's own IR transmitters built into the monitor. I chose not to use those because I wanted full factory functionality. I can select the DVD channel from the rear controller. The zone control features work so the kids can listen to whatever they want in the back, and the wife and I have what we want up front. Little things like that....

Hope that helps
