My requirement doesn't take away from your needs in any way because my problem is with the color choices, contrast, etc. A good choice of colors, contrast and font sizes can provide for both needs (which it certainly hasn't all this while). When I go around, I usually don't keep the phone on hand or use any navigational aids (for various reasons, including not letting Google know where I am at what times and dates). There are times when I want to map out a walking route or a driving route and just need to memorize some of the street/road names to know how I'm headed. That also helps me later so that I'm not always dependent on a map that's not in my head. There are also many turns around the world's streets where there are no distinguishing landmarks as such. For people who follow the navigation aid all the time, these things don't matter.
