Hey everyone! I upgraded my 12 charger with the larger touch screen that has Satellite and Navigation. Unfortunately after doing so the Navigation tab doesn't show up and my temps are in Celsius. I took it to my local stealership (Autonation) and asked them to update the computer, but they just looked at me funny and said that they couldn't do that. Is there a way that I can update it myself? Or maybe try a different shop that can update it? I love the upgrade just annoyed that not everything is exactly right.
