that's why we have spoken commands with street names - one doesn't have to look at the screen - but, the screen does help when one gets a zoom pic version coming up to a major freeway turn off.
spoken english - any country, any language - doesn't matter about funny names -- if you can understand turn left in 40 metres and then turn left now ---------- you are ok.
if one can't understand that - one probably shouldn't be driving anyway
nothing worse that two people in a car - one with a map upside down and both yelling at each other.
