Not sure if this is in the right section, I own a 2007 Galaxy with the built in Ford touch screen sat nav, I have purchased a 2008 updated disc with update 5.0 and inserted into the cd rom and it says not a map dvd? Is there only 1 type of disc or are there different types, the newer Galaxy has the Sony system in, mine is the Ford one. Any help would be appreciated?
