I have made a plugin that shows the next intersection very zoomed. I find it more useful than only the navigation arrows. Up to now it's for personal use and it's not yet part of OSMAnd but if there is a real interest I can take the time to see how to properly integrate it.
Additionally, by clicking in the volume button or the headset button it shows the following navigation instructions. My goal was to use it while hiking, take a look at the phone and with the volume button see the following actions and avoid spending much time looking at the phone. The same on a bike trek (using the headset button).
Here is a screenshot of it. So if there is enough interest and I find the time I can discuss with osmand team on the best way to integrate it.
Best regards
