Aftermarket NAV and cameras

Mambomn

As I have decided to go with the aftermarket navigation option and will have to wait until December to receive my factory order, I am now looking into the different components to build my system. Due to the lack of rearview visibility and from my past front bumper experience with my 300zxTT, I really want to install rear and front facing cameras. Ok, here is what I’m thinking right now:

HU: Kenwood DNX890HD- two camera inputs, HD radio, Garmin Nav, 7” screen, high quality unit that will improve the sound quality of the stock Bose system
Front camera: Kenwood CMOS-201 (good reviews for quality and low-light image) or Pyle Front-view bullet camera (low price, good reviews)
Rear camera: Kenwood CMOS-301 (cool multi-view feature) or Ebay Nissan camera (clean OEM look, low price, but concerned about quality and durability).
Speakers: stock bose- I know that that there are many better options, but it sounds good enough to me plus I can always upgrade later.

The plan is to get all the components at amazon or crutchfield and have a local audio installer do the installation. For those of you who had their systems installed, any idea of the installations cost?
Everything seems pretty straight forward, but my only concern is the wiring of the front camera (I plan to mount it inside the front fascia).

If you guys have any other suggestions or opinions, please let me know. I still have until December to buy all the necessary equipment.

Thanks…

Dude on here that goes by bigaudiofanat that is really knowledgeable about this. Hope he chimes in or PM him. Just don't tell him that Bose is better than Polk audio. However, if you did get the stock Bose system you are in for a world of hurt from my understanding.
