UK 370z GT Ultimate + NavTool + Reverse Camera + iPod control?

[octet]

Hi guys,

Looking to source some interfaces that would help getting the reverse camera fitted and being able to play from iPod with the option to control from steering wheel buttons (next track / prev track, etc) an not through the AUX stereo jack, also being able to charge the iPod.

I've purchased the NavTool at a very good price from ebay, made an offer of $150 which was accepted and should get it quite soon.

My zed is a Nissan 370z GT Ultimate October 2009 (standard version, not Connect Premium), so it doesn't have Camera Menu in the hidden settings

I was looking to something like this:

Peripheral iSimple PXAMG/PGHNI2 iPod/iPhone Adapter

or

ISNI572 ISIMPLE iPod/iPhone Radio Interface for INFINITY and NISSAN Vehicles NEW

or

Digital iPod/iPhone Adapter Interface for select Nissan/Infiniti Factory Radios

but we don't have HD Radio in UK, we have something that is called DAB Radio, totally different, so I won't need that option.

In terms of reverse camera, is this the best option?

Kenwood eXcelon CMOS 210 Universal Rear-View Back-Up Camera

Anything else you recommend? Is the cheap copy as good as that?

SONY CCD Car CAMERA For Nissan Livina Cube GT-R Pulsar Versa Fairlady 350Z 370Z

Can anyone please advice if the NavTool will work with this interface as well? Any other options to be able to do the above?

Thanks!
