The rounding off to 5 is my doing. Editing icons with speed of 20-150 at increment of 5 is painful enough, so I added logic to round up to nearest 5 increment. Maybe I should round down to be safe, LOL! But you're right about using audio for info instead of looking at GPS unit while driving and get into accident. The large icons with number are nice if you want to browse around. To be honest, I never seen so many alerts in such small area. I'll try rebuilding with original navitel icons tomorrow. Fixing to go to sleep now.
Edit: As promised, here is a build with original Navitel icons and Cyclop icons of similar size. Tell me how it's working for you and post some screenshots.
