There’s 2 cameras highline and lowline, highline comes with bendy lines, lowline doesn’t, mine has got trailer assist so has the highline in it (but I’ve programmed it to lowline because it works better)
As for the difference between the nav’s the pro has a hard drive so you don’t loose a sd card space, and you can load your somgs on your hard drive, also if you get the AID clocks the pro will show the map on both screens at the same time, whereas the lower model it’s either on one or the other, I’m sure there’s more but I’ve not seen the standard nav
