I think that the nav does show which side the destination is on. I'm basing this on my 2016 X3 and I'm doing it from memory. But I think it puts a "tick mark" on the vertical bar indicating the side of the street the destination is on. Something like my crude drawing below. Tick on the right; destination on the right. And it has a checkered flag next to the tick mark (not shown in my drawing).
