Does anyone else have Navigon working after their iOS5 upgrade? Mine seems to crash instantly on launch (screen fades out, then right back to the homescreen).
It turns out that I had to give my phone ANOTHER reset (Home + power button reboot), and then Navigon launched again. Just closing it in the app launcher did not fix this. You'd think that with the 9-million reboots of upgrading this wouldn't be necessary.
