What should I do? Is my best bet the dealer? If you have any direction, it would be much appreciated.

 

Did you do any mods recently, such as upgrading audio?

 

If you upgraded your stereo's head unit lately, I agree that would be the first place to check and make sure you didn't pull any wires or cut anything wrong. Many new head units aren't compatible with our navigation systems, but this issue can be worked around carefully. However, if this isn't the case, I would recommend checking all the components to make sure nothing is loose or broken. Let us know what happens.

These are the exploded diagrams, hope it helps.

So I checked the cables and connections and nothing changed. Then I was driving the car for another day and everything started to work. No problems with it at all now. Crazy, but awesome. Thanks everyone for the input. It truly is appreciated.

 

Hm, strange but I'm glad your problem worked itself out

 

Yeah-good thing. Fixing the navigation can be costly....
