I have a USB port in my car for playing music/charging my iPhone 5. This issue was happening randomly on my old 4S as well, but is much more prevalent and immediate with the new Waze app update.
If I have my phone plugged into the USB adapter, as soon as I open Waze it crashes. I've uninstalled the app, restarted the phone, reinstalled the app, restarted the phone again, and even with my settings wiped, the issue still occurs.
The issue does NOT occur if the phone isn't plugged in. If I plug the phone in after setting my destination, it will continue to work... as long as I don't change to another app or pull down notification center. Otherwise it will crash again.
I've sent numerous crash reports from the app to Waze and was wondering if there was any other ideas/suggestions out there to solve this issue, as it seems to be getting worse with each new app software update.
