Lately my nav has been going wonky again. It's showing me being where I'm not even close to. Is there a way to reset the nav. There is no disc to pull, shutting off doesn't seem to do anything, nor does shutting off the truck for up to half an hour. I even checked to see if maybe I didn't have any satellites working for me and I had 2.

I know I should bring it to the dealer, I will at the next oil change, but until then is there any type of reset, maybe by pushing a combination of buttons on the head unit?

 

A full Reset requires that you pull the Battery Cable (I'd suggest pulling the fuse first), and waiting about a minute before restoring power.
You gotta remember that the whole damn truck is a network of little computers, and the Off button in front of you rarely is as "Off" as one would think...

 

Yep, disconnect the negative battery cable. I'd wait longer than a minute though. Maybe 5 to be safe.

My parents were able to correct a wonky RER in their WK Grand Cherokee by doing this. Keep us posted!
