Is there a way to upgrade the entire sync/nav/MFT system? I have a 2010 Taurus SHO with Nav, and just bought a 2011 MKS with the same nav/sync system. The Nav system on the MKS is customizable, colors, photos, etc. My SHO is stuck on the blue background with orange letters. Is there anyway to update the system on my SHO so it has the same features as the MKS? Could the dealer do this, or am I stuck?
