Thanks to Pure Maps my XA2 h4113 serves as navigating device now and i have some observations.
(Sorry for spitting them here and not doing proper issues to Git)

1. The current speed is displayed halfed on xa2. Going 40 shows 20 Km/h and so on.

2. The road signs showing the next exit are very nice already, bravo.
2a. Only the german translation for "exit" is hilariously wrong atm. Currently "Beenden XX" means "Quit XX". "Exit XX from current Road" would be "Ausfahrt XX".
2b. But the exit/ausfahrt numbers are not commonly used here anyway. Many (early&mixed) signs are even missing them.
Propably leading to confusion when the first info we give on the sign is not there in real world?
I propose to move the first line "Exit XX" to the bottom of the sign below the actual destination city names.
2c. Also the word "Ausfahrt" is never written out on german signs. It is indicated by a white number with white circle around it on the bottom of the sign as the word Ausfahrt is very clunky and long i guess. So no need to give away screen estate for a word even german officials do not use imo.
2d. All Caps is not necessary for the city names on the sign. It increases character spacing and does not resemble the real life signs. I would advise to remove allcaps and increase the font weight to compensate for better readability.


3. UX wise, (reflecting my expectations when moving from Waze/Here/Sygic to Pure Maps)
3a. Always center on current position when Pure Maps starts. Currently the map is centered around the last known position and a tap on the top right "center" button is required to move the view to current position. It would be nice if the map view would resemble the actual current position always and as soon as it is known.
3b. The "Follow me" function should not be an option to select but be standard on app start and always on if no route exists or the user does not manually drag or pinch the map. Removing the necessity for that settings option completely.
3b. Colors of the position marker (Blue circles) and the route (blue track) are too similar and sometimes look slightly messed up. Maybe change the position marker to black or something funky, ad some drop shadow to it or use a 3d modeled one as soon as a route is displayed? (I could gladly help with designing one if you explain the constraints)
3c. The "Navigation" menue option/page should contain a list of past destinations, currently you have to tap the "to" field for them.
3d. The "to" field in navigation page should be the search field you get when now taping it.
3e. For the end user it is hard to understand why the search results in navigation and search page differ. When using the search in navigation page (Stadia Maps?) i hardly ever get a result for my (maybe to lax) keywords. The exact keywords in search page (using OpenCage?) however reliably give a matching proposal. Either explain to the user how to use the search or better move to the most reliable search engine allover.

I hope you can make any sense from my explanation, if not i am happy to further elaborate.
And again, it is near unbelievable how sophisticated and generally awesome Pure Maps already is from a tech POV. I now wish you a good hand in finding a sane way to streamline it for the end user and still stay true to your ideas.
