found this on another site it may work for you?
I had exactly same problem, with my q3 from 2013., Fortunately it's managed me to solve this. Actually it's pretty simple, below I can guide you how to get the exact location again. Go to navigation, then tap in to settings, now click on "insert location" which is in the bottom. Then you just enter your currently location, and everything should be alright again. Hopes this guide finds you well.
