Thanks for making this video. It was a little hard keeping up with how fast you were going but thanks for getting to the point. Have you figured out if the latch needs to be used in addition to the seat belt to clamp it down? Thank you.
We didn't use latch. You actually don't need to if installing in rear facing mode. And given the manual (www.nunababy.com/media/catalog/manuals/n/u/nuna_exec_im-0291d_us_1.pdf) page 45 & 46, using seat belt to install is preferred. And do not use latch if child is over 35 pound(page 46). Also from the graph in page 7, you'll see when to use latch(lower anchor belt) and when to use seat belt. Hope this helps :)
