I am no BOSE expert, but here is what I know:
The BOSE system uses balanced line inputs/outputs from the head unit to the BOSE amp. Most aftermarket head units and amps use unbalanced input/outputs. If you connect an aftermarket headunit to the BOSE amp, you may get very low sound levels, distortion, etc. The proper way to interface the 2 systems is to use a Line Output Converter or LOC. Peripheral Electonics and other companies specializing in audio interfacing sell them.
Installation:
Install a LOC on each of the 4 channel inputs to the BOSE amp: right front, left front, right rear, left rear. The BOSE amp will take care of splitting the signals to the various speakers including the subwoofer. There is also an AMP ON signal to power the BOSE amp. Most aftermarket headunits have a remote amp wire for this purpose. Also, use an aftermarket adapter to connect to the factory harness and simplify your wiring. This way you can always re-install your factory headunit.
As for steering wheel controls, the converter you need is specific to the head unit you will be using. Peripheral Electronics has a compatibility listing on thier website. See my earlier post.
And finally, you will loose the factory Bluetooth features. The AVIC-F90BT appears to have Bluetooth capabilites so it may not be a loss.
There are a few other posts regarding aftermarket stereo installs. Check out the Rogue Glossary sticky at the top of the forum for more information.
Good Luck!
