This video is here in case it helps anyone. Don't have the cable info but basically everything plugged in as expected as long as you use the 2009 and earlier cables.. the Backup camera was the only tricky one, it plugs into one of the two plugs where the LCD was, the one that doesn't have the split off dongle cable attached to it. This screen was the 13.6 PX6 ordered from Phoenix Automotive

Couple updates. First, Phoenix Automotive confirmed this is indeed the QX70 'Install Set', but suggested that changing it to G35 Car Type (vs G37) under that option would improve the sound and it seems to have. Secondly, didn't realize it, but the top bar scrolls across and there is a 'Car Info' tab that shows fuel info and stock tpms info. It's in KM and Kpa and noway to change that, but still some interesting info (though for me, the stock tpms doesn't really work since I have a bad sensor which allowed the other 3 to show up once but then now none of them do again). They also noted that the 'System Info' 'touch' functionality on older models that would bring up some back end car info is no longer available, or at least not on the version they sent me... it's blocked by the head unit manufacturer.
