OK, I'm using 5.00.20wp and to fix the problem of time/date changed by software: Go to tools--->settings--->display--->color mode, i noticed if i keep (auto) between day and night, it will changes my time/date.
P.S. I use DAY permanently. my time/date has not change since then, just give it a shot.
Edit: is there any way to speed up the way the vehicle moves when navigating.
Thanks in advanced.
