Navigation can be hit and miss for routes to destinations that's not usually visited. Peak hours are the worse. If it says 30 minutes, you have to add in at least 10 to 15 minutes to the journey. When you see icons reports sometimes it's not there. Information lags so much. GPS can get lost too and puts you in the wrong side of the road thus reroute you. Happens when you are on not familiar roads and also brings you so much further and lost time.
