My GPS stopped working. The navigation system thinks I'm 100 miles from my actual location, and there is a red bar through the letters "GPS." Owners manual reveals no fuse for GPS. Thoughts?

 

red bar means no gps signal.
Could be your antennae.

 

As mentioned above, it is most likely the antenna, but it could be a number of other factors, including: a bad module, electronic interference, or even something as simple as the weather blocking the signal.

I had this happen to me on my old LR4 during a horrific storm, and after it passed, the fault went away and my navigation system worked properly.

 

Came back all by itself. I did nothing, save for a quick slow down to avoid hitting someone who pulled out in front of me.
