05 Acura MDX w/ Bose: Replacing Stereo & Nav, Adding Subs & Amp: Questions and Issues

I have a 2005 Acura MDX with Navigation, Bose and On-Star. I am trying to get an aftermarket android LCD Stereo, to replace the stock stereo, but need the proper wire harnesses. I also want to replace the stock Nav Screen with a stock Computer Trip Screen that is meant for the same car, just without the Nav part. I might need use the Radio Bypass Harness, I'm not sure. When I plug the Trip Computer unit into my vehicle that had the Nav, it only shows the clock, and won't let me access anything else.

Can I replace a 2005 Acura MDX Trip Computer unit inside a 2005 Acura MDX that has a Nav unit? The plug on the back is the same, but the Nav unit connects to a DVD drive under the seat, and shows you the reverse camera, while the trip computer unit does not do that. How do I know which wire in the Nav plug is the rear view camera feed, etc? I want to replace my Nav with the Trip Computer because the Nav requires a fully working Nav disk and drive to load up the interface, while the trip computer doesn't require that to boot up.

I also have a KAC-9106D 2000 watt amp and two 12" subwoofers that I would like to add to the vehicle. I don't know if I need the "Honda Amplifier integration Interface" adapter, there must be a Bose amp in my car somewhere, because I have Bose speakers. Also, I was hoping to disconnect the stock Bose sub and connect the wiring to my subs using a line level converter. Here is what one person said, is he accurate?:

"Here's what I did on my 2003 Touring/Nav: remove the grill to the rear sub, remove the sub itself, detached the wires leading to the speakers, and rerouted them to a line-level converter. The line-level converter, which basically converts amplified speaker-level signal (mono in this case) to line-level signal, has red/white RCA outputs, which I then fed to the aftermarket sub amp I mounted under the third row seat. Finally, I "earballed" the signal so that at 75% volume on the head unit, my amp was getting a non-distorted signal. It works like a champ. Sounds great, since the Bose sub-amp (which I could not access) is doing all the crossover work."

This is what I have ordered:

This is the stock stereo and Nav system that I have: .gl/A8qh9bHyvbgkNpch6

This is the Trip Computer that I have, that I want to replace the Nav screen with:
ebay /itm/04-05-06-ACURA-MDX-Trip-Computer-Display-Screen-A-C-Clock-78200-S3V-A220-OEM/172821677534?fits=Year%3A2005%7CMake%3AAcura&hash=item283cf985de:g:t2sAAOSwqOFb6xDN:sc:USPSFirstClass!80104!US!-1

This is what I want to still work:

1. Stock Steering Wheel Controls, I have volume down, volume up, channel button, Bluetooth button 1,2,3 and 4.
2. Stock Reverse Camera. I know the wires for this is in the plug that goes into the NAV screen, but I want to know which wire it is so I can remove it from that plug and connect it to the aftermarket stereo.
3. Stock AM/FM Antenna.
4. Stock GPS Antenna.
5. Allow the Trip Computer/Touch Screen/AC Controls to function when the aftermarket stereo is installed.
6. Make sure all stock Bose speakers in vehicle still work.

What I would really like to know is what all the specific wires behind the stereo and Nav do.

If anyone has any advice, I would love to hear it!!!

Thanks again.

AUX 3.5mm cable car audio input: Just plug the device into the extension port of the Acura MDX 2005 factory car stereo, connect it to your favorite MP3 player, iPod, iPhone, Android device or smartphone, and hear the CD quality music right away.
