Hi [Minh_Nguyen]…
THANKS… MUCH… for your prompt and Very helpful reply. !!!
I was also very impressed with your knowledge and technical skills being able to replicate my issue using different navigation engines. I had no idea that was possible. There is much about GPS navigation I simply take for granite.
The name of the GPS App I use is called: Magic Earth. It seems intuitive to use and I find its user interface friendly. One button takes you to a menu for “HISTORY”, “HOME”, “Favorites” etc. Maps are all offline so no active data required. And ETA projections seem fairly accurate and nicely presented visually on screen.
Initially I got involved with OSM to just add posted Speed Limits which is a feature I like most using GPS. Then one thing led to another, driving more inquiry. 
The community here is always so friendly and knowledgeable. Your reply in particular gave insights on more than what I had asked for.
Thanks much for the broader explanation.
May all your navigating be safe and efficient…
