Is there a way to install the backup camera into the existing screen/system?
Welcome to NICO!
In the earlier models of the 2003 and 2004 M45, the screen size was different between the NAV and non-NAV models was different - I do not know about the software (in the TCU and other places for the camera) is the same! This may be an issue in the later models too.
In other words, if you just buy the OEM Infiniti camera and install it (assuming that the wiring is in place too!), I just don't know for sure if it will work.
You could get a friendly Infiniti dealership to try it out and see what happens.
An alternative is to get one of the newer after-market cameras and use that - there was a review in Consumer Reports some time back (and I think that particular test is available for viewing on their web site
http://www.consumerreports.org). Some of these products use wireless connections for the video feeds to make installation easier. Screens are smaller than even the non-NAV screen, but may be sufficient for you.
Please let us know what you end up trying and doing!
