Hello, I just got the 2019 BMW i3 that came with parking assistance with a rear cam and front and rear sensors, but no stop-and-go cruise control. In other words no technology package. The question is? Did anyone add the package themself after buying a 2nd hand i3 that didn't have it? And maybe someone saw a talk about it that helped someone achieve that? I searched all over and it seems no one tried to buy the parts to install adaptive cruise control, brake assist, lane departure. Any help from experience would be great!
