I've been using Nokia drive in the uk for a while, and really do love so much of what the program offers, but i'm a little puzzled about a few things, and I was wondering if anyone can help me out?

1 - the situation with traffic. Do routes ETA's take into account traffic when calculating, and if so does it dynamically update if a jam up occurs ahead of you? (In UK)

2 - sometimes I'm driving and its says 'route recalculation' for no reason I can fathom. What is happening there?

3 - My commute live tile seems to have stopped updating with morning traffic info - worked a few times, now the live tile does nothing

if anyone has the answers I would be very grateful to hear from you!

thanks in advance
