Issue with 2010's Lancer Navigation System
 

Hello everyone! I own a 2010 Mitsubishi Lancer and drive it daily to go to my dental clinic, where I work. But I am experiencing some issues with its navigation system. My GPS signal gets lost in the middle of the driving, and sometimes, the navigation symbol just stucks in one place. Restarting the system is not helping me. What should I do now? Hoping for some help.
