On a regular iPhone 13, the layout will be fine in both portrait and landscape mode. The only remark / suggestion I have is to increase the font size from the distance indicator (e.g. 200m , 300m) to the next action (turn, left, runabout etc.).
When this FONT is bigger, it would be perfect in my opinion, probably it is possible to manually adjust the font size, or increase it 'fixed'
Goed punt. Ook de reden dat ik momenteel twijfel tussen een “normaal” en groter model iPhone. Zelf instellen zou top zijn.
Yes yes yes!
Here's one I made earlier as an example:
Make the distance number the same size as the road number and the time.
The thing that matters is the number. The units (m / yd) can stay small since they can be inferred - thus saving a little space.
And the associated thread:

I was testing the Navigation app last month in the alps (with here and there rougher asphalt roads).
I the had difficulties in reading the EXIT NUMBER in the traffic circle symbol).
I find the font size much too small.
I suspect typical MRA users are slightly more - er - 'mature' than the average bikers, and thus don't have such sharp eyes.
I look forward to a feature like the Zoom++ where I can pump up the font sizes all round. 
@richtea999, don't hold your breath... Self setting of fontsize causes all kinds of layout problems. From text not fitting in designated space to overlapping buttons and tiles. There are already uncountable screensize, resolution and aspect combinations as it is. In the end we all want a decent view on the map too 
I agree totally with the point about the font size in the next turn box. It is way too small, especially for those spectacle wearers among us. It should take no more than 1/3 second to see exactly how far I have to go to my next turn but the font is way too small.
Glance down, peer, squint - look at the road for heaven's sake!!! Try again...but of course the distance has changed so even though I got an idea of the numbers the last time, now I am starting again. And I should be watching where I am riding. And then suddenly I'm on it and going too fast.
The road description and number at the top is almost irrelevant to me, the most important thing is which way do I turn and in what distance. That, for me (and everyone I ride with) is the single most important piece of information on the screen and it should be the largest piece of information and the most easily seen and understood.
