21' Expedition Limited looking to add backup trailer assist. Just knob?

Bought a 21 Limited Stealth expedition that did not come with pro trailering. It appears that I already have all the cameras and trailer module. Can I just buy the trailer knob and plug in to activate the pro-trailering feature?

Can't answer your question, but I find the system to be pretty much useless. It works, but I find it harder to use than steering by myself. Especially true if you are in close quarters and need to watch the front end.

Still. Would prefer to have it. It simplifies things for her and if it keeps my boat safe, I’ll take 2.

I'm looking to do this on our 2022 Expedition Limited (already has 360 degree cameras). Did you ever find a way to do it?
