I've had this problem a handful of times since I purchased my car. It persists as I drive, which makes me think it's not a GPS lock issue. Here's what I notice:
- Google map car location is a few miles away from actual location
- While driving, google map arrow is moving in a completely different direction - therefore as I drive, the discrepancy becomes larger
- Turn by turn navigation map is stuck at my origin point
- Reset dash and center console has no effect
- Resolves spontaneously within 24h
I've pointed out the problem to the SC twice when the car was in for service. Also sent them photos of the map with simultaneous screenshots from my iPhone showing the discrepancy. Each time they come back with "tested, working correctly." However the problem is real yet intermittent. They updated my software thinking this will solve the issue; did not work the first time, let's see if it recurs after the latest software update.
