Nav Screen Keeps crashing
HI there i have a 2016 DS4 crossback, all of a sudden my car's nav screen keeps crashing and rebooting itself. some days the problems goes and have full functionality without issues, but the majority of the time it constantly keeps crashing. I have tried the mapping update, disconnecting the battery for a while to maybe reset the system but no luck yet. any ideas how to fix this situation myself if possible will help. Spoken to DS and been told will cost around £170 for someone just to look at the problem and would like to avoid paying for something i hope is an easy fix.
