Great work m8. Wasn't able to test it while driving but I have one thing to ask:
I display some FD data in RR like next turn and next street. It all works really nice but once I arrived at my destination and continue driving or I cancel the route the FD does not update this data any more. So I still have something like "Turn left" and "Abbey Road"
on my screen. Can you make FD update those variables or whatever you wanna call them so nothing is displayed?
