In-Dash DVD Monitor Installation HELP!

Hello, I just purchased an aftermarket In-Dash DVD Monitor with TV Tuner, CD/DVD/MP3/AM/FM Radio, and Mounting Harness for my 1999 300M. I intend to place the motorized monitor in the place of my factory radio, and put the CD/DVD/MP3/AM/FM Radio in the empty slot below it. I won't have any problems mounting it, but I would like as much help as possible with the wiring -It's my first install. Has anyone done this before and could give me some tips? It would be awesome if anyone had a write up about there installation or a guide that would show me how to do everything! ANY HELP IS GREATLY APPRECIATED. The models that I purchased are below. -THANKS!!

u can get aftermarket install kits that will plug into your fastory radio harness for 15 bucks from best buy. Just tell them what setup u have either 2 /7way connectors or 1 /22 way connector.

There aren't any Best Buys around here. Do you think Circuit City would have it?

haft to look any audio install place would carry them.

Yeah  circuit city should have it as well check their audio install area just make sure you know what radio you have in it now its either a 2 plug  1 black one grey or a 1 plug  one that should be it.
