X260 Passenger Mirror woes

Long story short(er)….had to replace my passenger side mirror assembly. Found a fully tested working used one, that had all the same features(blind spot, reverse cross traffic, folding, etc…) Installed the unit and started the car to test it out. Now I’m getting dashboard warnings that blind spot detection, and reverse cross traffic is disabled. Any clue as to why? Your knowledge, and expertise are appreciated. 2016 35t prestige AWD.

Can you use JLR SDD to reset the side mirror from there in the software?
