Default Factory Amp

This may seem convoluted and I may be obfuscating the issue, but, then again, I drive a Crossfire...

First, let me say that many folks on this site have been very helpful (ppro, in particular). After much deliberation and searching, I finally decided on a Pioneer DEH-P7000BT. But, when I was about to pull the trigger at the Crutchfield site I received the warning shown below. I tried other receivers and kept getting the same message. I 'd really like to keep the factory amp as I'm not sure I have the knowledge to perform the steps outlined

I have the Factory Stereo w/Navigation.
I want to keep the factory amp, but when I input my car with this unit at the Crutchfield website I get this warning:

What you need to know:
  • The harness does not supply connections for the front speakers, so you will need to run new speaker wires to your front speakers.
  • The harness does not supply connections for the rear speakers, so you will need to run new speaker wires to your rear speake
  • You will need to bypass your factory amp by running new speaker wires from the radio to the amp location and splicing the new speaker wires to the factory speaker wires at the output side of the amp.
  • If you replace your factory radio, you will need to use an aftermarket amplifier with a low-pass crossover to retain the factory subwoofers.
  • When used in this vehicle, the functions of the yellow and red wires in the Crutchfield harness are reversed. The yellow wire supplies ignition power, and the Red wire supplies constant power.
I thought I'd see what would happen iif I input to the Crutchfield website that I have the factory radio without Nav or Infinity system. When I do this the only warning I get is:

Even though I have the stock system with Nav/Inifinity system, I'd really like to keep the factory amp mainly because of cost and my limited knowledge of the wiring required.

The stereo installs I've seen on this site merely swap in the Schosche VW-01B. However, the stock system with Nav/Ifinity seems to require a lot more.

Since I have hearing problems a good sounding unit is not a priority. I'm looking more for a unit that will pair with my iPhone 3G and USB input, satellite radio and a couple of aux in ports.

Does any unit out there keep the factory amp?
If not, what can I use as a substitute for the factory amp to meet the requirements above and keep the factory speakers?
