I have the Ford Sync system. The maps are from navteq. It loads via the SD slot in the center console. Current version is A5, available on eBay from ~$50 and up. Sync updates are available via download from syncmyride.com. While the initial system release in 2011 was horrible and still in beta mode, the Ford team rewrote the entire application, switched mapping providers, and has been very consistent about their commitment to the Sync system.
