Signal dies. No data. No GPS etc.
Go to locations and disable the 'allow google apps' or whatever (not on CM at the moment to look)
Then start navigation and see if it helps.
I had the issue on 4.1 and this helped, just had to disable it everytime I wanted to use navigation, and re-enable it so google now would work..
Not sure if it still works, but worth a shot.
