Binnacle… google it! It’s the housing for a ships compass or the instrument cluster on a car (or motorbike). Yeah, I’d look at the giant map but as it constantly zooms out it’s less than useful. In Europe we have lots of smaller streets and roads/junctions within metres of each other (a metre is a unit of measurement!)… the ‘supplementary map’ as you call it is covered in text and the main map is showing me a map from a couple of miles up! Both then are rather useless. My point was… a bilingual binnacle map text is totally useless, especially if you don’t understand one of those languages!
I don't need to google binnacle. I've driven in Boston, NYC, etc... in a Tesla and also driven BMW's in London, Wales, Greece, Italy, Spain, etc... so I'm familiar with what you're talking about. I don't have this issue. I can control the level of zoom on my "main screen" and I've never had multiple languages stacked on top of each other. I don't know what that's all about, but sorry you're having issues. GOOD LUCK!
