Hey Weapon,

Did they say it interferes with backup camera? Because I have the T Harness Backup camera addition: Fits 2009 - 2014 Nissan 370z Navigation Video Interface Add TV DVD Backup Camera | eBay.

Not sure how well that would work having two T harnesses, etc.

Never Mind, I found the O/M Install manual and it has video camera inputs included. It seems "OK" but I feel that my current setup gives me adequate BT iPod emulation.
Of course it would be wonderful to get Carplay on the Navi head unit but that's not possible unless I replace the entire head unit and the Navi dash with the Cubby Dash, etc.
Right now I don't believe any Asia bridge device maker can offer CarPlay legally, even if they could get the Apple SDK somehow.

They said backup cam option is coming soon but they didn't give me any other information other than that. The infotainment system has video inputs on it.

I have a similar navtool backup cam. I wouldn't see why it wouldn't work since it overrides the screen signal.

I think the infotainment doesn't override other controls like the navtool so i would assume it would still work. Personally i'm not too concerned about it because my navtool started working intermittently about 2 years ago. Sometimes it has a video signal and sometimes it doesn't - very frustrating. So I would be happy to get rid of it.
