Galaxy S3 Bug: Navigation app crashes when clicking "Start" Summary: Route navigation crashes on starting of route finding.

This is an intermittent bug. It only started happening recently - I think it coincides with when on a desktop browser I volunteered to start using the new version of Google Maps. (I wanted to use the new traffic monitoring feature). I didn't realise it would propagate my choices to my phone as well. 

Is there any fix? E.g. 


How can I configure the navigation app on my phone to use only the more stable mainstream navigation app?  
How can I configure my Google account to revert to the mainstream version of Google Maps, for all devices?
Are there any third party apps which have route navigation similar in quality to that of Google's?


Thanks
After you enter the starting point and destination, the app gives you the possible routes. On that screen the best route has a start navigation option; selecting this causes the app to crash. Instead select the route you prefer and then hit the start arrow at the bottom right corner. Works for me.
