Mirror upgrade ?

[Xoexpireu]

I purchased replacement mirrors on eBay to eventually upgrade to blind spot I have the entire replacement housings with mirrors my question is. Is there anyway to test the replacement mirrors for functionality before I go taking off the old ones and door panels?

No, You can't test them without taking the door panel off. also, if these mirrors have more features, they have to be programmed.
