When the vehicle is started, the GPS location or vehicle direction indicated on the MMI navigation map does not match the vehicle?s actual location or direction of travel for a long period of time (often as long as 10 minutes). The issue occurs in open sky, with no large buildings obstructing the sky view. The issue is intermittent, but it can occur for long periods of time during a single day. The issue may or may not resolve itself. When the issue occurs, the GPS navigation system satellite reception shows 0 satellites. Due to the infrequency of the issue, this might not be verifiable. (To view the number of satellites being received, go to Nav >> Route >> Select Current Position (first item in list) and scroll up). A DTC related to the GPS antenna or MMI system may be or may not be present. If the sky view is blocked because the vehicle is in a parking structure, below ground, or next to large buildings, it is normal for the GPS location or vehicle direction indicated on the MMI navigation map to not match the vehicle?s actual location or direction of travel. The blocked sky view prevents the vehicle from receiving satellites, and the system may be temporarily lost (for example, the system may show the wrong location on the map screen) until four satellites can be received. This behavior can last for several minutes even in clear sky view when the vehicle exiting a parking structure or underground structure. The MMI can take up to 5-10 minutes to sufficiently get a 3D-GPS fix once the vehicle has clear view of the sky. This is a normal condition, and is not related to the condition described above. Replacing the MMI main unit, replacing the GPS antenna, or updating the MMI software will not change this behavior. A potential antenna hardware failure can affect some model year 2014 - 2015 vehicles.
