I called support about this three days ago. The navigation in the car shows the car in the wrong location. I drive 35 miles one way to work. It was drifting off a week ago after a software update (also after having the windows tinted). Support got it working but it did the same thing yesterday. Today it is stuck in one position. Anyone else experience this issue? They said after it started working again if it did the same thing again I would have to have the GPS recieved replaced. They stated it is having trouble finding the satalites. They quoted me $1,300 to replace it along with them having to replace the back window so I'd have to go back and get that tinted again.
