I am not sure if I should ask but here is my question. I just bought a Garmin 60CSX GPS and I am looking to buy the Garmin TOPO US maps. I have searched the internet for an answer with no luck. Maybe somebody on this site knows the answer if they use the 60CSX with US TOPO maps. What is the difference between the latest TOPO US 100K maps (DVD version) with the black label and the TOPO US 2008 with the blue and white label?
