Did a search but can't find anything

I have a '13 ZL1 with MyLink and Navigation system. It stopped working on me the last month or so. Every time I turn the navigation on, it just stay on one location somewhere very far away from where I am. The is no gps signal I can see. However everything on the MyLink system works. All the buttons, settings, radio, xm, usb, etc.

I am trying to take it to a dealer soon but I want to know before hand that if anyone have experience with his malfunction. I'm hoping someone in this forum can explain what needs to be done. Is this a software fix or a MyLink replacement situation?

Thanks
