Hi all. Had my Legend a week now, and just finding out all it's foibles. Thickest car handbook I've ever seen! My question is, what does the black box mounted under the parcel shelf do. Is it the means by which the satnav gets updated? Not a big issue at the moment, but I haven't found anything in the ,manual about it. Absolutely love this car, keep finding excuses to pop down the shops for small items, then getting lost on the way home and accidentally doing an extra 50 miles!!
