I’ve non-US Rogue with front collison and non-adaptive cruise control systems. If I buy some required parts, Is that possible to work ProPilot system?

ProPilot Assist is not plug-n-play, meaning that you can't simply add a couple of parts and it's good to go. It's an integrated system requiring precise calibration. For example, "if ProPILOT Assist detects that a driver has removed their hands from the wheel it will go through a series of alerts to get the drivers' hands back in place. It can even bring the vehicle to a stop if it is not being used as it is intended."

Are you up to replacing and/or reprogramming the BCM so that everything will work together?
