  1. When I start using my navigation system, this message pops up all the time and I don't know why. It says "Nav SD Card Message. Once initialized, this Nav card can only be used for navigation in this vehicle." Then you would press the CONFIRM button and everything starts to work. But why do I see this all the time when using the navigation system?
