It literally took only 5 minutes once I had the patch cord. I removed the external Sony stereo using the two removal tools that came in the delivery packet and instructions. You pop off the Sony's removable faceplate, you also have to pop off the plastic trim piece that goes around the edge of the unit to conceal the opening. This trim piece has to be carefully released since it is rather thin and you don't want to break it.
You then can slip the tools into the slots at the sides of the Sony, this allows the unit to "unlatch" and then you can pull it straight out. Be careful now, there are several power, audio, and video connections that have to come through the mounting "sleeve", and the edges of the sleeve are sharp sheet metal. I only pulled the stereo out far enough to access the Aux connectors which are part of the harness coming off the rear of the unit and were clearly marked "Aux Input" and were not already connected to anything.
I used a 3' or so piece of wire, snaking it down behind the TV and towards the stereo opening. A helper here is useful to grab the wire through the opening the stereo resides in. Again, be careful of the sharp metal edges. I then temporarily taped the patch cord to my wire and pulled the wire and attached patch cord up and out so I could connect it to the TV audio outputs. In my case (a Continu:us TV) the audio "out" connections were located on the left rear edge of the TV. I had to use a mirror to see which connection I needed, but was able to then plug them into the TV by "feel", verifying proper connection with the mirror afterwards. That saved me removing and replacing the TV itself. If you have a different model TV your output connections may be harder to access.
Then I plugged the other end of the patch cord into the Sony's input connections, putting some electrical tape on them (and the other A/V connectors already there) to keep them from accidentally coming unplugged bouncing down the road. I tested the system before sliding the stereo back into the mounting sleeve to make sure everything was good.
On my external Sony there is a "Source" button that cycles through all of the inputs such as AM, FM1, FM2, DVD, and Aux. It shows which one has been selected on the Sony's small display. Aux is what I need to choose to take in and amplify the TV's input.
Good luck, I hope your setup is similar and this works for you.
