The navigation on my 16 C7 has stopped working. I have the X through the GPS icon.
From what I have found so far it appears it may be the communications interface module. As I have no competent dealers in my area any troubleshooting help would be greatly appreciated. If it should be this module, can this be replaced without a dealer tool?
The issue may be due to the antenna becoming disconnected. Check the antenna connection behind the rear-view mirror panels.
