Hi,
I don't know how you do in US when you want to park in reverse by night. On my motorhome I have a rear camera but I often ask my wife to guide me and it's not always easy to hear. I do not know if your wives are the same in U.S. but I often had difficulty understanding his actions (right - no, other right - stooooop - too late ....). I bought a pair of walkie talkie and now we have no problem to understand us. (For safety, when I don't hear talk I stop immediately)
